Really love your videos!! These get me really excited!!!! Thank you can’t wait for more!!!
Thanks! A lot more coming
Wow! Just wow!
I would love it more if this is a manual but I understand everyone has their own choice.
Good work!
Yeah man I’m a manual guy myself
Excellent Job again Erik.
Love these modified corvettes.
Awesome video!
Thanks brother- you’ve got he Mack daddy of them all. Come see me soon I’m ready for round 2…
Man I love your philosophy behind why you build the way you do. I’m in Dallas TX. 2014 z51 manual c7. What would this cost? Partner with anybody in Dallas that would build this way? Not opposed to taking the drive out either but it is 1200 miles
Thank you. After 2 decades in the performance business, I really can say that I prefer a smaller shop. It allows me to really dial in the process and provide better quality and service to the client. That’s why I can offer. I cannot speak for other “larger” shops out there who may not have that kind of operation. We’ve had clients send us vehicles from all over the country because of our business model and the way we do things. I’d be honored to help with your project. Email me for more info. Happy 4th! - Erik

Awesome stuff dude!
Thanks Ian!
Beautiful C7 GS! The after market wheels are fantastic. With the after market lowering bolts, the car has a very aggressive stance. How does the front splitter survive with the front end so low?
Thanks! She does just fine- no issues…just have to be careful!
cant wait to get this done on mine. already got headers and e85. expecting a +250hp gain with the upgraded fuel
Best of luck!
You are gonna need more than that for 250. Cam And ported polished heads E85. Maybe. If you wanna stay all engine
Great job!
Thanks!
Great work in a big sea of corvette mod shops!
Thank you. Agreed....that is why I stay small, stay humble, and stay in my lane.
Your videos are better than Redline Motorsports in Pompano Beach, FL. Why, you ask? Well, because you're more personal and friendly. Their videos are devoid of people and are kind of just cold to be honest.
Glad you’re enjoying the content- we have a lot more coming!
Sick looking Corvette
Thanks a lot
How much power would you expect or have you seen with just the A&A kit and no other mods except maybe intake and an X pipe etc?
~120 rwhp gain on 6 psi and 93 on moderate timing
Gorgeous Vette. 👏👏👏
Thanks a lot, I appreciate that.
Nice Job
Thanks a lot
This video is awesome. It’s not like so many others that just waste time.
Thank you David. Glad you enjoyed it. Take a look at our other videos...you may like those too.
Wow great job and that chop is chopping
Thanks..... Sure is!
Nice!
Thanks!
Beautiful car, but 600 whp seems low to me, I’m not used to the LT1 engines, but a Gen 3 coyote can make way more power with fully stock internals.
Hey thanks for checking out the video. Boost is really low on this at up- the bottom end could use 3-4 more PSI but then we have to add fueling upgrades…the idea here was mild cam, low boost, moderate timing and no fuel system upgrades- and that’s what we built. 700 or so is about what I will push on a sbe LT1 at 11.5- CR.
Great video this is the kinda build I want to do could you give me some specs on the cam
I have a 2014 C7 Stingray A6 A&A kit Ti head unit 3.6 pully. 1 7/8 long tubes catless x pipe stock NPP. Stock heads cam n bottom end. MSD intake manifold Katech 103 mm TB C7ZO6 fuel pump & injectors plus DSX low side pump DSX flex fuel setup plus Alky control water methanol injection running 50/50 blend made 622 whp n 570trq on a very hot day here in Farmington NM. That was a E50 blend of flex fuel and 91 pump. Made just under 600whp on pump 91. 9.5 lbs of boost.
Imagine what it would do with a cam
@@floridahighperformancedon’t cams statistically make cars last less mileage or mo
@@logantrisilla6579 camshafts themselves don’t necessarily affect longevity. It has a lot to do with overall maintenance and other valvetrain components. More aggressive camshafts do put more wear and tear on things like valve springs and valves, which is why those items are always upgraded to handle increase lift, duration and more aggressive ramp rates.
Hey, I'll be getting a 2020 Camaro ZL1 1LE very soon. With the same idea you did with this Corvette what would you recommend for the Camaro? Pump gas is 93 unless I'm travelling I could be stuck with 91. I live Canada.

Thinking about adding a super charger to my C7 what’s the turn around time and cost approximately. I live near your shop and thinking about upgrading my Grand Sport.
Hi Charles, thanks for being patient. Please email me your info to Sales@flhighperformance.com
Loved the bloopers classic..
My fav part of the video...that's 10% of the actual bloopers I commit LOL!
This is a very good video! I can never understand why some LT1 can make that kind of power on the stock fuel system. I had to get LT4 injectors, LT4 HPFP and a DSX auxiliary fuel pump. All that for similar power gains, did you delete DOD and VVT during this build ?
Thank you very much. We didn’t go overkill on the boost- only 6lbs. Everyone wants that high boost PSI - which means higher fuel demand. It’s a balance. The cam helps too which has a larger fuel lobe on it- which drives the HPFP harder and creates more volume. Yes VVT is deleted as well as AFM. We solely use LME billet timing covers on ALL LT cam swaps- no exception.
@@floridahighperformance from your experience does the 38% fuel lobe shorten the life of the HPFP?
@@85net not if preload is properly set up. Number one killer of HPFPs is improper install height…
@@floridahighperformance awesome, thanks for the knowledge.
I had to upgrade my fuel system as well. I think this particular car made such good gains because heads n cam. More efficient
What are the offsets for the wheels on the car I have a z51 and want a good of a fitment as what you guys have done just not too sure what to order
Thanks for checking the video out. Keep in mind the z51 doesn’t have the wider body like the Z06 and the GS do, so you’re limited on offset. However- get with the right wheel company and usually you can have a nice 3-pc wheel made with aggressive offsets- even on the standard C7 body. Call my friends at Strasse Forged- they made a set of SM5’s a long time ago for my turbo C7. They were concave as hell and beautiful and fitment was spot on!
I just picked up a 2018 Grand Sport 12/26/23!
I want that set up, sounds perfect. Isn’t that car supposed to make 460hp stock though?
Congrats! Yes, 460 is at the crankshaft. We rate power at the wheels, which will always be less.
Very informative, I am in Virginia can you supply parts and support to my local shop? I am retired and budget limiting. Can I cut back on some the parts or work? 2014 C7 Z51 A6 10,000 miles about time to get that A&A kit and a few support parts. Cam Sounds perfect! Head work??? I like headers but saw a 3 inch down pipe to 3 inch mid pipe I thought might work ok enough. Very well done project and video. The perfect setup for my 2014. Dennis in Virginia
Thank you Sir. Email me sales@flhighperformance.COM

When adding these power upgrades do you have to delete the front radiators
We upgraded the engine coolant radiator to a larger Dewitt’s- as well as a larger fan from Dewitt’s specific to the C7. It did require some modification to the A&A charge pipe that routes up through the passenger side of the engine bay to the throttle
Body…mostly trimming.
I decided to delete the cooler that was at the front of the car for the trans, as the vehicle has an aux trans cooler near the rear bumper as well. If I wanted to, I could have kept the cooler and made my own bracket to move it up to gain clearance for the IC, but since this isn’t a strict race car and considering the use, there’s not one single detriment when removing the cooler. The car has been running fine with out a single issue with trans temps….
I have that same Corvette Grand Sport and would love that upgrade. I live in Houston TX. How do I get that and what does it cost?

How do you not have more subscribers? Great video
If you build it they will come...takes time!
Very nice.
Thank you
Are you using stock oil pump or the katech oil pump ?
This engine has a Katech pump.
it would be nice to know how much a build like that costs
Around 20k or so…parts labor tuning
@@floridahighperformance
That's very good compared to most shops
Doesn't the 18 C7 come with the LT4 low side pump from the factory ?
20k for 200 hp? 😭😂 oh nooooo. While b58’s are getting 100-150+ hp on dps and tune.. going for like 2.5K max
I have got a 2015 Z51 stingray. The car in this video would be exactly what I would aspire to have in my car. What would that set me back if you guys do it?
Thank you. Would be happy to talk to you more

Frank I am in Virginia with 2014 Z51 A6 let me know how this proceeds. Dennis
I have a 2015 non-Z51 lLT M7 Stingray with ARH long tubes, Akrapovic exhaust, AFE intake and tuned. It Dyno’d at 437 RWHP and 453 RWTQ. I wouldn’t mind adding a supercharger but I want to be able to keep the AFE intake just because I love the way it looks. Does anyone make a kit that would allow that?
I have made it work with custom fab....
Maybe one day I can get my ‘19 Z06 down there. Only looking for a 750 package.
Change that silly pint sized supercharger first then upgrade fueling
Hey there Noell, please email me at Sales@flhighperformance.com for more on this project!
Will these upgrades work on the 7-speed manual grand sport?
Yes it will
200RWHP IS A VERY NICE GAIN😎‼️
Thank you! With fuel upgrades we could add 2-3 more PSI of boost and E85 and probably pick up another 100 or so…

Does the grand sport c7 have a wider body than the base model c7
Sure does. Same wide body as the c7 Z06
I have a 2015 c7 z51, I don’t want a blower, as my car to is a daily , and the only car I have at this time to use, unfortunately, I want power to , I wanna stay up with the new c8’s, how can I get that same power match , if not more on my c7 z51, auto, I done the the lowering bolts, and General Motors mag ride up grade as far as mods, ( nothing serious ) but just a preference for me, help me get power , what can I do to it to achieve me getting into the 11’s in the 1/4 mile. All stock, I also have the NLP exhaust sys , thank u in advance ,
Ps
Budget is around 2500 or so
Hey how are you. $2500 is a tight budget- 5k would be better. Bolt ons and tuning would be the next step for you…
Cost on the engine work?
How much power can u add without deleting warrant
This package is right at 20k. Warranty usually is voided in some way shape or fashion when adding performance mods...
Was wondering if you could help me with my c7 want to do some work on it
Sure thing sales@flhighperformance.com

Hey I would love to get the custom valve covers from yall.

Do you know what the offsets were on those wheels front & back?
off the Vossen box....front 28 rear 40
Thanks!

+40 on the rear is the most aggressive I’ve seen with the HF5 on a grand sport, most of the ones I’ve seen have been +45
How much would the engine modifications run for on a '17 base stingray?
Around 9500 for a head cam package which includes all parts and labor/tuning. Supercharger not included

What was the cost of that build? I have a 19GS
About 20k all in with the wheels...
what stage is that cam? also is it on stock piston?
Stage 2 NA from GPI. The NA camshafts work fine with centrifugal style superchargers like the A&A kit shown in this video. If it was a top mount supercharger like a Whipple or Magnuson, we would have went with a positive displacement friendly camshaft.
Yes stock bottom end

What’s the cost on the upgrades that got the 200 gain? 🤔
I'm currently trying to build a car like this. This is the question we all really want to know.
20k or so
How much for a 550wheel hp package on this car?
About 10-12k
What would the turn around time be for say a 550 wheel hp package…. What would be done to it?
@@gz4405 we don’t provide guarantees on completion times on performance builds- too many variables which are out of our control- like other vehicles causing delays, parts issues, etc. no reason for I to take more than a few weeks start to finish though- if you’re looking for a ball park. We don’t rush- we take our time with these builds and pay great attention to detail along the way- which takes time.

@@moderngrub1876 it’s a lot of parts and a lot of work- but the gains justify the cost in my opinion and we are barely working that car. It’s got another 100 rwhp in it easy if we add some fueling upgrades.
SO HE WENT IN PLANNING ON SPENDING 6-7K ENDED UP SPENDING 30K
No, he came in expecting to pay about 20k all in, and paid 20k all in. 30k? I wish. Thanks for checking out the video.
What did that run you 20k? Why not just buy the z06? lmao. The LT4 is a better motor
Um, well, I don’t know. Let me goes ask Jimmy LOL! I get your point - believe me- I agree…but my dude had a GS and didn’t want a Z06…different strokes for different folks. Go watch my BAD PUNKN ZL1 video- I’m an LT4 guy all the way!
Depends on what your goal is. The way this kind of centy set up and the roots system on an lt4 make torque is radically different on the curve. IMHO nobody needs 650ft/lbs at the hit in a 3,500lb car with DOT approved street tires etc - chassis can barely handle it - some would say straight up can’t handle it like Pobst - which is why the 06 and R1 are notoriously twitchy. Plus hes getting all the upgraded cooling and etc in that number if I understand it correctly. Not to answer for the shop but on a road course there would likely be a lot of unhappy z06 guys wondering why they spent the money on that and not on this… just sayin. There is a whole lot more to being fast than simple peak hp/tq and 0-60.
Also - as to the lt4 being a better motor outside of the cam drive, which I’m sure is a roller now on the cam upgrade, the vast majority of the improvements between the lt1 and the lt4 are in the heads. Given that this car is now running CNC’d heads and that the AFM has been deleted (thank god) - and I’ll assume given the quality that this shop seems to have that they did all the other bits as well (springs, arms, push rods etc)- these heads are SIGNIFICANTLY better (meaning bullet proof and breathing like crazy) than stock 06 heads. So an extra 15k-20k more for a stock zo6 over a stock GS or 20k for this vs a stock z06 (all the same final number being the point) - this GS is better in almost every way.
Just buy a Z06 and save a few thousand?
You're not wrong...some people don't want a Z06
Nice car, but auto 😢
I am a manual guy myself...but as time goes on, they are harder and harder to find!
What will this build cost, less the wheels.
Less is more fellas. Feel free to NOT stick a Vette emblem anywhere you have enough space for it. Looks tacky. Looks like a Mustang owner also owns this car. You know the type. Dudes that stick chrome on their door handles, window trim, etc. Ghetto ass rats. So, please be classy. Otherwise beautiful car.
To each their own...thanks for checking out the vid!!
So buys a 50k GS spends 25k to make it a base model c7z06 ??? Buy a c7z06 , tune headers e85 and you have the same hp
Maybe he didn't want a Z06? Gotta ask Jimmy my boy.
