GTM Performance Engineering VQ45VHR-Our Journey to The 1000 HP and Beyond

#452-LE · 09-14-2010, 05:36 PM

... Going to GA this weekend in the Jeep to unwind a bit. Leaving Thurs. lunchtime-ish. Perhaps we will be towing the bikes down for a few Blood Mountain passes, but we will most definitely hit up the Papadeaux in Alpharetta!!! I accept donations in the form of gift certificates left at the hostess counter. Not to mention, I have a few lady friends at that place called "Tilted Kilt"...

BTW on topic.... Not 1000HP, but I will be shooting for the 500 mark.....soon.

Anytime Slow! The car will hopefully be at the WERA Grand National Finals in the 2nd weekend in October @ Road Atlanta.

Next Summer this car is going to be Insanely sick! haha if I ever sold it it would have to be in the dupont registry or to like r2b2 motors down the street. lol

Hey bullitt,

How many actual miles have you driven in a 370Z? The sense I get is that your car gets worked on more than driven...you're an owner by proxy!

bullitt5897 · 09-18-2010, 10:51 PM

Haha dude I only have 15-16k on the odometer lmao and I had the 2nd fully loaded white z on the east coast!!! The first one got sold out from under me *it was a transfer from another out of state dealer*

VHR with HR head...

1slow370 · 09-20-2010, 10:51 AM

but the vhr head has bigger ports, better cooling, superior low end torque and idle, less hotspots and revised valve area's. Not to mention if you get rid of the vvel the engine can't be throttled without going standalone and/or cable throttles anyway

Q8y_drifter · 09-20-2010, 11:50 AM

If you're pushing for 1000whp then bigger ports, better torque curve, etc. don't matter IMO as that is really designed to push the limits of a factory stock N/A engine.

Better cooling? The HR has no oil overheating issues due to the lack of VVEL and in term of water cooling it's pretty much the same.

Is GTM going to use Osiris?

bullitt5897 · 09-20-2010, 02:45 PM

@ Slow: Sam and I had this conversation of whether to run a motec or not and after our discussions Sam convinced me that he had a better method than the Motec system. Since we are running the HKS F-con Vpro full standalone unit along with Race Logic Traction control system and a few other pieces to bring this system whole.

I am also an Aim Sports dealer and will most likely be installing a AIM Data Acquisition system in the car with possibly a Digital dash in my headliner. that way I can monitor everything from the motor to the suspension and be able to overlay it on to a 3d mapping/google earth overlay of the race tracks that I go to.

1slow370 · 09-21-2010, 02:07 AM

yeah The only thing I'd say on the motec over what you have is the servo output for the vvel otherwise the fcon and the supporting boxes you have can do the rest of it. I was just mulling it over at 4a.m. running through the motec options and when i found the servo control it hit me. There is a way to tune VVEL right now, more accurately there has been ever since the car cam out. Can the FconV be hooked up to control the throttlebodies? If so i think i could still figure out a way to get you vvel lift control ability, it would just require a separate programmable micro controller box. If the FconV can handle the electronic throttlebodies or even a cable swap, this would be great as the price of an FconV would be much more affordable. I'm going to do some research and pile together a list of components.

Edit: as I am going to need to do this for personal reasons to get my twin screw to work anyway. Right now i kind of want to be able to just throw the damn stock ecu right the hell out of my car as there is going to be little to no support for it.

bullitt5897 · 09-21-2010, 09:37 AM

Slow you might want to give Sam a call and discuss with him the options and maybe throw some ideas around. *hint hint* Sam knows wayyyy more than anyone else in the aftermarket about the VVEL system and may be able to shed some light on how he can tune the system... I cannot say for sure if he has cracked the system or not but from all the evidence that I have seen and heard

I would put money on Sam knowing how to tune VVEL

Here is Some teaser pics of the GTR manifold, this was a big undertaken to say the least.

Sam told me how much time and effort went into making this work. I think it will all pay off because I know a bunch of people going to get em' when the production model comes into effect and I am one of those people. Thanks Bullitt for being the test subject.

The thing I like anout these is if the silver is too boring for you, you can customize the color, even polish is possible. Not sure if Sam will offer custom options but the mani. is a work of art no matter how you look at it.

Edit: I would love to see a carbon mani. cover on that bad boy
