I am in the UK and confirm all that is suggested about Mike at BR, if they dont sell it, they consider it rubbish and they will attempt to put people off and go to them. They also have no issues with personal insults to other companies offering parts and services to Aston Martin customers.
For those of us who have met Rich I would defend his honor to anyone. He's a very bright and humble guy. And he knows quite a about about Aston Martin, particularly the V8 Vantage. Shortly after I got my Aston about four years ago,I purchased some exhaust parts from AP and he came to my house to help me install them. We did a few other minor things that day, but he just asked for a nominal hourly rate and some beers. Really upstanding guy.
in ground school I teach the guys.....start on the third date 😁
sex first then dinner and if it’s still happens you can meet the parents .....this model has always worked very well for me
and if that fails... EP STEP: Enter Autorotation - turn into the wind and hopefully... get to fill out the report...
Oh God. This is so unprofessional. Never pick a fight on the internet. I'm a nobody. I have nothing to lose. You have your entire business. What a moron.
If braking at your first round-about causes brake fade on your DB9 like he says in the video? You should probably stop getting your car serviced at BamfordRose.
This is me on the front straight at Thunderhill with a 100% stock DB9, full brake from 120+ mph for the first left hander. All day long. Again and again and again. No fade.
His math is very wrong. He is comparing gains of reduced compression engines verse high compression versions.
ie, if the stock engine at high compression is 140BHP, then with 8psi boost is 200, he is claiming only 60BHP from boost. Actually dropping the compression ratio reduces the normally aspirated BHP to close to 100HP, making an 8PSI boost gain of 50% in the ball park of reality. You can not include the loss of power due to dropping compression ratio and then factor it towards an engine where no reduction was made.
Bascially 8PSI on an engine at 11:1 should be close to 50% more BHP assuming the fuel and timing are okay. His premise on the gains is very, very wrong. Take the GMR kit at 8PSI on 420BHP 4.7L and you should be north of 600HP. I would prefer to see 5 to 6psi personally.
Also the static compression is not as important as dynamic, again, many, many high compression cars with 5 to 8psi kits on them running fine, especially with water or meth injection.
He wants the kit to not work so strongly. And GMR wants it to work equally as strong. I guess once we get one here to dyno, all will be revealed? As I stated above and on the original youtube video, having not driven the GNR version, I can not comment on the claims, other than to say they are possible. Now whether GMRs tuning is up to snuff, I can not say. But to put out a blanket statement that high compression engines can not handle low boost with proper tuning is just incorrect.

As a self-proclaimed "engine performance engineer" he should know better. This is quite sad and embarrassing. I hope someone reigns him in a bit before he does more damage to their brand.

I actually appreciate his direct, no apologies approach. I like the channel. It's okay to disagree on some things. I can see how it could be off putting to some.
Perfect example is the C7 corvette, 420hp stock. With an Edelbrock SC kit 599HP with the stock 11.5:1 compression ratio. Thousands of corvettes run SC kits at 11.5:1 using meth or water injection.
Dear " Redpants" !!
As you can verify, i have bought some Stuff from you, during the last 2 Years.
Mostly Parts that has the same Origins as other Cars in the Conglomeration of
Ford - Aston - Volvo - Mazda- Jaguar during the 2000...
But also the beautiful Airfilterholders that you have had produced, and which make sense!
When You try to start and sell Superchargers from from GB, and You cannot take the debate with BR: s
Mike in a serious way, I get very annoyed...
In his reply to this " new " thread about supercharging the Aston - Anybody who thinks about doing that, must be
totally insane.... Check the " Second Round " out.... https://www.youtube.com/watch?v=5SiI...

PS. I was interested in supercharging my 06 Vantage, but was not impressed by Grahams excuses for not being able
to do a fore and after " Roling Road Comparsion " of my Vehicle.DS.
My Car - Aston Vantage -06 . Partly modified to later look, and changed interior for some Carbon Parts and a better Navigation System..DS.
This was a much more professional presentation from Mike, without the swearing and testosterone of his first one, so that's good, its a presentation that will work better with Aston owners, most of whom will be used to a more measured presentation in their business lives.
So, on the content, considering the BHP of the Rover and Mini using absolute BHP to measure gains doesn't scale across to a 4.3 or 4.7 litre engine. It really needs to be a % power gain, so if you see 47% power gain on a 2-litre engine, then you'd expect around a 47% gain on a 4.7 litre engine. It won't be 64bhp extra, it will be 197 bhp more. Which is around what GMR claim for the power increase on a Vantage.
The Mini engine gave a 40% power increase, so that would be equivalent to 168 bhp on a 4.7L Vantage.
Don't know why the Jag only achieved a 21% increase in power from all that boost, but its quite a long way short of the other two examples that Mike offered.
It will be interesting to see the results from some of the converted cars to settle the discussion
I don't have a GMR blower so I don't actually know how good it is, but as for the math in the video:
Stock Toyota Camry 2GR-FE 3.5L V6: 10.0:1 compression ratio, 236-268 HP depending on year.
Stock 2014 Lotus Evora base 2GR-FE 3.5L V6: 10.0:1 compression ratio (no blower), 276 HP stock.
Stock 2014 Lotus Evora S 2GR-FE 3.5L V6 with non-intercooled blower: 10.0:1 compression ratio, 345 HP stock.
My old 2014 Lotus Evora S 2GR-FE 3.5L V6 with non-intercooled blower: 10.0:1 compression ratio, 430 HP on the stock blower at ~10.5 PSI.
All of those cars had identical short blocks and heads. The Evora's 2GR-FE had different ECU, intake & fueling, and exhaust stock from Lotus. My car did not detonate on 93 RON octane fuel in Florida summer heat, even without an intercooler or water/meth injection, and without the louvered back "glass". Without the pulley, but with the headers/tune/airbox, it was good for 380 HP. Here's a link to what mine had done to it.
There's a newer intercooled setup now - keeping in mind water/meth injection accomplishes the same thing as the intercooler - that nets 490 HP (the newer factory intercooled cars are 430HP stock). BOE has one coming out soon that claims 511 HP at the crank.
Would I personally want to push my Vantage that hard? Hell no. Is it possible to do it safely? Most likely.
The previous version of the kit was running 6.5 psi, if I remember correctly. Changes to the water injection system, intake manifold, and tuning let GMR safely bring it up to 8 psi.

Do you have ship dates for GMR kits heading the USA? Think I want to get on the waiting list.
They're being assembled and prepped now, should start shipping in a week or so.
I stopped taking orders for them when a couple of the component manufacturers shut down due to closures during the pandemic. Once I've confirmed production is resuming, I'll starting taking orders for them again. I seriously hate how long my pre-orders had to wait, and I'm beyond thankful for how extreeeeemely patient they've been, and I don't want to exacerbate the situation even if I'm staring right into the light at the end of the tunnel.
I'm in the guitar business and have had some models take well over a year to come in from Japan, with no pandemic or anything other than typical business as usual, some supplier problems, taking the low bid and getting the poor result and having to change gears, the list of delay reasons can be endless. I never stop taking orders unless my personal backlog of work is out of control, but for future incoming I'll take your 10% deposit and explain that it could be the 6 months they claim or it could be 18 months and I or anybody else in the US has no control over it. Only place your order if you understand and are OK with those parameters. I've had typical parts special orders take over a year to come in. This is typical in international business. Not everybody runs on railroad time, sometimes the clock is right twice a day.
This year? The list of product that won't be available till mid 2021 is staggeringly long, typical stuff that would be 3-4 months. This is directly pandemic related and the fact that everybody that ever wanted to learn how to play guitar decided they should give it a try while they were on lockdown for 4 months, so sales were to the point stock of entry level pieces are about sold out. Unfortunately I only sell high end so while it's been a good year, beginners were spending in that $500 range and not so much in the $2000+ range.
I did enjoy the popcorn I made for the video though!
