These guys do all these posts and market themselves, but when it comes to customer service, they are left wanting. Tried to contact them regarding suspension upgrade and still have not heard from them
550HP on the dyno. czcams.com/video/odfD6E-7_TQ/video.html
I have seen several high compression (10:1 to 11:1) cars in our local clubs running 6 to 8psi boost with water or Meth injection. The amount of boost you can run on a boosted motor depends more on the effective/dynamic compression ratio (taking both compression ratio and intake valve closure timing into account) than it does on simply the static compression ratio (swept volume/combustion chamber volume). Having not driven the kit myself, nor put it on a dyno, I can not vouch for the GMR kit, only that many cars with similar compression are boosted with great results.
I have GMR:s original product on my 4,7 MY10. Works brilliantly!
So when ROUSH /Eaton - Kenne Bell Supercharge a 2015 Mustang 5,0 with a compression ratio of 11:01 from 450 hp to 6 - 700 hp - and having done it for years - you are telling us it's not possible.... I think you should reconsider your arguments
Coyote v8 has dual injection system with dominant direct injection and that's why they can run higher compression ratio plus SC, not the case on AM v8 since it's port only my friend.
This has been very eye opening, their website said how they would not sell to other people to DIY fit etc. This matches up with them wanting to do their down tuning to avoid the limp modes, selling to Redpants must be because they have decided to lax that rule and actually sell more than 30 kits.
Someone in the facebook group has put his kit up for sale as he works at Aston Martin works and a customer has had a engine failure (I believe) warranty claim declined because the car has GMR kit
Remember that Lotus supercharge the Toyota V6 in the Evora & Exige by simply bolting it on. Obviously with optimised settings for fuelling etc, but they don't open it up at all. It is just a standard engine as bought from Toyota. The naturally aspirated engine is good for about 275 bhp and the latest supercharged engines are making 430 bhp, all with a manufacturers warranty. It is clearly possible if you have the skills and the knowledge. I am not saying GMR do have the skill but it should certainly be possible.
Praise your own product and stop bashing others - business rule no. 1 even for kids....
Partly true but it's incredibly frustrating watching other businesses make claims that are dubious, have business practices that are completely unethical and yet people fall for it.
I see it all the time in the sector that I work in and it pisses me right off. There's just no point being truthful.
@@Jimbo8012 what is dubious and unethical about GMR Superchargers
@@merstrand1 - If GMR are making wild horsepower claims that are significantly higher than what is achieved in the real world than this is extremely dubious and unethical and potentially breaking the law under the Misrepresentation Act 1967, the
Sale of Goods Act 1979 and the Supply of Goods and Services Act 1982.
Bamford are not only specialist to raise the alarm on some of these wild quoted horsepower figures.
@@Jimbo8012 he is wrong his arguments are wrong - Mustangs 5,0 has a similar high compression ratio 11 to 1 they have been supercharged for years by ROUSH /EATON KENNE BELL - with gains over 200 hp.... With no problems
@@merstrand1 If you had one fitted you would know exactly what is dubious and unethical about the claims made by Graham at GMR. I did and I do.
To be fair and show that results are not always the same, here is a Vanquish S taking a 4.3L SC Vantage. The vantage should have walked him, especially with the early lead. More power and less weight. I had a 928 Motorsports SC on my Euro 928S with 10.4:1 compression at 7psi. No water injection. It was a CIS system so no fancy computer issues though. czcams.com/video/S7bPzKsE7X0/video.html
Another SC vantage. 4.3L @ 9psi, ESX kit. Owner ran stock internals until he hit around 550WHP. He's the forums still. To say you can't SC a Vantage at a reasonable boost level with solid results is just not in line with proven results. Perhaps the one you test drove had other issues? czcams.com/video/eTf5REA0BNY/video.html
Nicely put.
Did you see that supercar program that had Afzal khan and his two sidekicks Ronen and Ronan. They appeared to get some beans out of it but had to uprate the exhaust clutch and brakes think they also had to do a remap. I assume GMR pretty much bolt it on and make some minor tweaks and hand it back????
Your thoughts???
I have seen it.....bunch of backyard mechanics in my opinion, don’t like his work or styl at all
@@gregvos8599 Not sure if you've covered this topic already Speedshift Vs manual would be interested in your thoughts on a video?
Well, the 4.3 really does wake up with fi. The detonation limit is around 10psi with 100 oct(R+M/2) fuel and centrifugal supercharger. Cylinders 4 and 8 are the ones at risk for a few reasons. Of course the engine life is severely limited but no one without a bucket of cash and extreme desire would go done this path. Here is my car 10 years ago:
czcams.com/video/l4c_y2Ku6j8/video.html It’s now had a complete rebuild with strengthened block, fully cross drilled, big intake and inconel exhaust valves, heavier valve springs, c&c’d heads, head bolts, head gasket, custom pistons and rods, double thick top hat liners, exhaust cams advance to zero overlap at boost, 9.5 C:R from trick pistons and a ton more. The electronics is easy after you have reversed the code in ida pro and understand the algorithms and all data table and scalars. I’ve even written a launch control subroutine which can use the cruise control stick.
@@markrodger8540 This is very interesting. As someone who was about to go down this (bolt on) path with his 2007 V8, I am now thinking to do it right is much more involved. Is there a tuning shop (or website) that has the knowledge that you have clearly acquired that could do it right? Secondarily, your Aston in the other video is a beast! Do you mind telling us what it was putting down? Thank you.
sounds like this guy feels threatened by a competitors product.
Great Sheene quote.
Mike - i think it is distasteful to slag off the competition using the tone you have. It is beneath what I thought Bamford Rose stood for. Further, you have done a great job in marketing BR and demonstrating knowledge through quality content. That's driven potential customers your way I am sure. Sadly though the customer experience is then let down in a big way due to BR's unresponsiveness to enquiries. I have emailed once, cakes once and no - one answered, left a voice mail and a request for a callback yet each time, there has been no response. All that work you have put in to making great videos is then let down if the customer can't get hold of you. Victim of your own success perhaps? So I agree with an earlier poster - business rule#1 is don't slag of your competitors, rule #2 is before you generate demand for your product, make sure you are ready to handle that demand.
Called once, not cakes! Doh!
Love the comment, implying that chocolate can be very expensive with no full flavour 😂😂😂😂!
Hi all, I've called BR a few times now - this garage is rich in information and has some sound alternative advice, at reasonable pricing compared to some AM dealerships, - of cause I'm not say any AM Dealerships are bad ..... But you pay you money and have no upgrading choice!
Dyno?
Lucky I never liked supercharged cars, I really dislike all the screaming whining racket.. poor engine
Says it as it is! LoL
Did they ever turn up 😂or was that a stupid question ?
Poor mouse!
Don’t hold back 😂 pS if we had BR is South Africa’ I would have my car BR worked 👍
Lol 😂
