- We did a direct comparison on the new BTR 2 (Redhot cam) vs the old BTR 2 cam that is so popular in the 5th gen camaros, G8s, SS's , Caprices, etc on the dyno to see real world results.
We were VERY surprised by the results! - Auta a dopravní prostředky
Thanks fellas for this awesome video. It was good to hear the the cam itself and info… Gonna LS SWAP my 67 chevelle from a 396 to a LQ4 and was thinking of going with that same came from BTR… it sounds amazing. Thanks again
You're welcome
Now go see the gains at the track! Sheet looks good for sure. Exciting to see all the data and back to back testing.
In the works
This is the cam I went with for my build. GM crate LS3/Holley X max/Holley blk heart exhaust/headers/Tremec Magnum F/QP 9” in an 87 Iroc. I’m thinking of maybe having the heads ported before install. Great video thanks 🙏
Also I was leaning towards a stage 3 but worried about driveability. Can you say how different the stage 2 to the stage 3 is driveability wise? Low end torque, surging etc…
You're welcome
Not much difference, but we aren't huge fans of the 3. Good choice with the redhot
Lee did you ever get your car on the dyno?
@@ericordemann5806 No, I actually ended up buying an LSA supercharger and having the Heads CNC ported, rings gapped, trunion upgrade, LSA pulley/pinned, upgraded the timing chain tensioner and stuck with the same cam since it’s the same as their “Red hot cam” and their PDS stage 2 torque cam. So it’s put me back some. Hopefully by the spring I’ll have it in the car.
BTW
Great work on the G8
Gorgeous car...and sound wicked
Thanks
Glad there was a little idle clip in there. I was curious how it sounded at idle. Debating on doing this in my 13 zl1 that’s full bolt on.
They say it works great with PDS too!
Good stuff brother!!!
😎
Thank you sir
Love to mod my 2017 Chevy SS Sedan LS3; 6 spd Manual...with a Cam, BTR Platinum springs, Trunion upgrade, ARH, etc.
Was looking at BTR Stage II, to keep it fairly streetable (it's a semi daily). My aim is 485 to 500 N/A ??
I'm @ 30K miles now, so the bug has bitten me for sure.
Question: With the EXH Durr around 240 @050" (or over 240 on the new version II)...is piston to valve clearance in danger...all else being stock ?
No. These heads are shaved, no issue. Dont get hung up on a #
So is this the red hot cam or did they revise and replace the existing stage 2?
I have seen many people in forums talking. About the stage 3 even and the specs they had then and the lift and duration were less then and they increased the lift and duration from what I see on the website. So have the stage 3s been revised as well? It’s what I’m planning on for my LS1.
Redhot is the BTR Stage 2v2. Replaced the old BTR 2..
Im a little confused, is this stage 2 v2 or Redhot cam? BTR has both but I’m not sure which one you’re actually using since you mentioned both in the video.
They are the same cam!
Do you think the LS3 S2V2 is too small for a 418 with the right heads? Daily driver & autox, no formal drag, so i dont want lots of overlap. I'm thinking the smaller intake duration with a head that has high CoD could balance out.
Smaller, but OK. Would peak slightly lower
Absolutely love your content! What are the exact mods that have been done to the OrangePeel car?
Thank you!
Btr 2 v2
4dp converter
Ls7 maf
Pacesetter headers
Solo exhaust , mid muffler, solo Js
Eibach suspension, with large sway bars
CTSV brakes front and rear
Vararam intake
Im sure im missing a lot
I have the BTR stage 2 cam, bought it around the beginning of 2020, how do I know if i have the version 1 or 2? My G8 dyno'd 430/400 with VCM intake and 2" long tubes. The converter blips seem to be about standard for these stock G8 torque converters around this hp, right?
Yours is V1.
Our blip was fixed with some trans tweaks. It also has a Circle D converter, not a stock one.
@@nufnuffz28 Gotcha. When I spec'd the cam, I had asked around for opinions on the biggest cam I could run on a stock converter and the majority of responses was the BTR stage 2. Would that still be the case with the V2 or would you want a converter with that cam?
@@andrewroman4982 probably OK with the stock converter as well, but I'd upgrade to at least a 3000 or so stall for best results
I was thinking of this camshaft for my ls1 with fast 102 and trick flow 215 cnc heads @ 10.7 to compression ratio through a t56
Should work OK for that setup!
@@nufnuffz28 i hope so i have a hard time choosing parts . Which would you choose to make more power? More camshaft or more compression?
@@SneakerKidd101 compression at 11.7 on 93
How much were the 823s/5364s milled? And were they cnc'd or hand ported? Also, are the headers 1.75in or 1.875in long tubes? Anywhoz.. An extra 30whp gain at 6500+ rpms with a shop's revised/updated version of their stage 2 cam... That is way more than I was expecting! I bet the G8's owner is happy with those results! I know I would be. I was expecting to see 10-15whp at the most.
. 035. Hand ported by RCR about 10 yeaes ago. 1.75 we think. The V2 BTR cams do very well
Does this car have a catch can on the driver side for the PCV system returning to the valley pan? I see open air breathers for the passenger side fresh air in
This car had no catch cans
What’s a good size of stall for this cam? I’m thinking of going with a ZL1 converter and 3.27 rear end on my g8. Any recommendations?
Zl1 is useless NA... 3400 or so stall...
@@nufnuffz28 welp my bank account isn’t going to like my next purchases lol Thanks for the reply
im really hung up on doing stage 1 or 2 for a daily. any thoughts on the stage 2 cam in a daily stop and go traffic? does it push when stopped?
It will push some, but with a good tune it's not so bad. On a real daily, I'd like to stay with a stage 1 or Little Lunati
It works good with a manual. Can't say on auto.
You briefly mentioned how this cam compares to the stage 3, is this V2 stage 2 better in your opinion? Why?
In our experience the btr 3 doesn't perform even as good as the BTR 2 V1 on 6.0s.
This is a big improvement over both
@@nufnuffz28 What about for 6.2’s?
@@Tanner_Teves same. Btr 3 seems to not perform as well. Hop to the TSP 3 at that point, although the REDHOT number's still show well through an auto!
What cam would you recommend for a c6 ls3 auto with a stock tq converter was looking into the btr stage 2 v2 is there anything else you might recommend?
You guys tested this cam on any manual 6.2 LS3 cars?
Picked this cam up for an 08 manual Ls3 corvette and wondering if I made a good choice.
Yes. Search our channel. White Ss I know of
@nufnuffz28 you guys have alot of videos..link to the video?
@@doom26464 czcams.com/video/fic-Cx9fHpo/video.html
@doom26464 How did it turn out with the redhot on the vet? Whp?
@@paisley2342 car is still in storage waiting as I live in the far north. This late spring will be getting the cam
what kind of torque/stall converter are you running is this too much for a stock stall?
This had a 4dp. Id recimat least 2800 for this to be perfect imo
@@nufnuffz28 thank you sir
Question do you guys prefer BTR 2 over Rick Crawford Dragmaster cam?
RcR stuff works well. Overall its the combo and tune though!
Just bought this cam for my 6.0 LQ9 swapped C10. Can I talk to someone about getting my ECM retuned for this setup?
Sure. Email nufnuffz28@yahoo.com
Bro ik this comment is late but would this cam do well with a highram?
Not bad... but probably more rpm imo
What's the cause of the lifter failure? Which lifters were used when the cam was installed?
They were stock DOD lifters. Very common
@@nufnuffz28 you said they failed twice. I'm assuming that was before the cam change?
@@All_Stock_Garage hmmm. Never after we did the BTR 2... Maybe with the PO. I think it had a little lunati in it when we got it.
I am looking at getting this cam for an LSA blower and was wondering if I can use a ZL1 converter.
It should work, but will need a good tuner for a Zl1 converter to not push
@@nufnuffz28 ok, thanks. I just got with Joe Labruzza from G8only and he confirmed that it should pair well with the ZL1 converter
@@Tax_Mny love Joe, but more important to talk to your Tuner/builder about the direction you want to go. Like I said, make sure the tune is good to not push and you should be OK. A so so tune will make you hate it. There are several cammed LSAs On this channel you can look at. Claytons has a BTR 2 PDS torque cam and he is on a Zl1 converter...
@@nufnuffz28 Thanks for all of the helpful information. BTW happy Thanksgiving to you and yours

nice video, does anyone know what wheels those are?
AODHO wheels
How does the BTR 2 v2 compare to the GPI SS3 cam?
470 or so? Seems like an interesting cam spec
Would these numbers be the same or higher on a 5th gen camaro m6?
Higher... but not hugely
Stock converter or aftermarket?
4dp

would this be a great cam for caprice ppv?
Yes, with a converter
@@nufnuffz28 which converter would you recommend. I’m really
Leaning towards this cam.
@@screaming86 depending on usage, somewhere between a 3k and 4400
@@nufnuffz28 I’ve been leaning towards a 3200-3400. The 6l80 stuff is new to me still. I’m used to 60/80e stuff or 350/400’s and manual trans lol
I'm using the stage 2 LS3 cam in my caprice engine I swapped into a GMC canyon and got 452hp with a manual trans.
What stall did yall run
This car has a 4dp
Got cam specs old vs new?
Old Specs: 225/238 .620"/.605" 113+3 New cam 221/24X, .619/.617, 113 LSA
@@nufnuffz28 does that mean the new cam has no advance ? So it’s the same icl and lobe separation

Now my real question I also have a 233/242 629 615 115lsa no advance straight grind I ordered this when I was going to stay n/a. Planned on shifting around 7400 I was told by the guys at tsp straight grind on 115lsa would love high rpm. Now I’ll never know but curious what you think of the “n/a” cam specs.
Love the data ! Very helpful to us all thanks for the awesome videos

It should be straight
Is this the redhot cam or the new btr stage 2 v2 ls3
Both (same cam)
@@nufnuffz28 driveability any different from the old stage 2?
@@peterantonopoulos3373 no. Seems to drive the same as it did.
@@nufnuffz28 thank you for the responses. Much appreciated!
How choppy is the idle on the V2 vs the V1?
Same. Both sound the same depending on the tuning
@@nufnuffz28 cool thanks. My C6 is in the shop right night getting the V1 stage 2. This video makes me wish I had gone with the V2 lol
@@bwill03z76 always next time
@@bwill03z76how do you like the stage 1?
Automatic or manual car?
Automatic
Is that ls3 or ls2 ?
G8s are 6.0 with ls3 topend
So the block is 6.0 and heads 6.2 right?
@@3bood-414 heads aren't set for any ci.... just has to have standard 6.0 or larger bore
It's a L77 basically a 6.0 version of a LS3 I think they did it so they could use DOD. If I'm not mistaken LS3 blocks don't have provisions for DOD.
The G8 GT's came with an alum 6L with rect port heads aka L76 or L77 depending on year. Pretty much an LS2 with afm/dod lifters (but I don't believe ever were VVT motor) with rect port heads such as 823 or 5364.. Not 821s as those are LS3 that came with lightweight intake valves. And cam is pretty much just a 1-bolt 4x version of the 2001-04 LS1 cam. The reason it was only rate at 355-365hp was bc it was de-tuned to run 87 oct gas vs 91-93 premium like the rest of the LS equipped cars (minus the LS4).
