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

[QUOTE=bullitt5897;705516]Ok daniel, get this straight my car has been with Sam and several other shops over the past year. My car has 15k miles on it from about 8 months of driving on it. Now I make it clear to those who do work on my cars... You have a dealine that has to be met! I told sam that deadline and he is on schedule my car is also bouncing around from 3 different shops. This is a very realistic build time and what most people don't understand is that if you want your stuff done on time you have to be involved in the build. There are only a few cars that I know of that are at GTM for long periods of time and you know why that is???? Because some other *used to be GTM installer f@cked up the cars and sam has to go back through them and then wait out the legal battles so he can finish his work! I know several guys who have already sent there cars to GTM and had them back in 2 months or less.

Thank you and enjoy history

My car was at GTM long before yours was and has only been worked on by GTM. Same build as yours, built, stroked, tt, fuel system w/ twin pumps, ect...It has been there since November. Maybe I should have set a dead line that had to be met then I would have my car back. There are always issues with any major build so you should consider yourself lucky to have the build going as smooth as it is.

Do u have a problem with my post? I am only stating facts. As with any big build, bolting all the parts on is the easy part. Getting everything to work together and tuned is where the work comes in. I cant even count how many hours Sam has spent on the dyno with my car and its still not done. I wished the op the best of luck with his build and was merely pointing out that deadline or not there is a long way left to go. I find your post telling me to gtfo offensive and unnecessary .

Hey Mike any possibility while you are blowing barriers to the wayside and dropping untold amounts of cash that you could have GTM throwi in a motec M800 series ecu With the advanced functions for traction control and boost over run(wasted spark), Electronic throttle support with the multi throttle box, dual wideband support, an external knock box, Downshift blipping, variable cam timing, and the servo motor control?

Long story short hook up two servo brains to sensors on the back of the vvel sub-assemblies, and run their positive and negative motor wires to the standard DC motors on the sub assemblies. Then wire the motec servo out to the 2 servo brains and you have full vvel control as well as a standalone ecu that could easily handle all engine functions on your motor reliably.

After having talked to uprev i feel they don't ever really want to bring vvel out so the motec with a servo conversion on each head is going to be the way to go. You would need to have the throttles do all the air metering and then have the servo drive on the motec referenced to the rpm for the angle of the vvel system. I'm gonna go make a post in the tuning section this week to give a better explanation or just shoot me a pm but i figured out how to do it.

Edit: so long as you can control the throttle, cam timing, fuel and spark, you could use any kind of box that can create the reference signal for the servo boxes running the vvel motors, the motec just does all of it in one package.

Why wouldn't he just lock the VVEL out? You guys cant tune it, it adds more variables, and it isn't needed for high horsepower. I cant name a single mustang (yes we have variable valve timing too) with 600-800+ horsepower that doesn't have lockouts on the cams. Or at least limiters for that matter.

1slow370 · 09-20-2010, 09:13 AM

VVel is more than timing our cars can control valve lift and no, no mustang in history has ever had that. It is the sole reason our torque curve looks like a flat line, and why we can run a bigger "cam" than a 350z yet idle smooth as glass at 600 rpm. We don't have intake cams

Edit: while working on dreamers car you notice those 2 dc motors sticking out the back of the heads?

also as i just posted it can be tuned you just need the bank

didnt realize it controlled valve lift as well! I stand corrected

Awesome build! I have some OEM R35 parts (R35 OEM FMIC cores, R35 OEM Turbos) for sale if anyone's interested...PM me.
