That all depends on how much boost one wishes to run. We can adjust the A/F and boost to safe levels after the software is installed. Of course if one wants to run a lot of boost, the fueling will have to be reevaluated. If it is found to be insufficient then of course changes would need to be made the system itself to bring things up to par.

OK,

I would never use a UC...not even for my G35...however, what about a stand alone sustem like The HKS F-Con V-Pro. It is a GOD of tuning in the VQ communnity.

I local builder/tuner here in the Houston area who is very well known in the Supra Community approached me about tuning my GT2 w/ the V-Pro....I called him back...I wanted to have him install some Nitrous on my G35 (which already has the V-Pro) and maybe I would (if I liked his work/service) then be willing to discuss the V-Pro/G35 idea.

He never called me back (something I hate!) so he won't be getting my bussiness, but I am still intrigued w/ the idea of using the V-Pro.

Any opinions?

I guarantee your your duty cycle is over 90%. It is too high. BTDT and those percentages are with the 5 bar. You CAN not run the GT35s on that car with a 38# injector. Cranked up to 5 bar or not. Period.

That is irresponsible to even suggest. A gt35 will move a lot of air. It no longer comes down to boost, it is pure CFM. That turbo is much larger than the K16, K24 and even the GT28.

No, not those. You will need to use a system that can handle many channels. For example, you need a channel to control valve lift, a channel for cam advance, a channel for DBR and so on. I think you get the point. A Motec system handle this and we do it, but the expense to build the harness and tune it is huge as opposed to using a system like what we have in place.

When is a system like that make sense…when building a motor of such into an old chassis or race car.

Thanks, Stephen,

I will stay away from the V-Pro for my Porsche (although they have 32x32 resolution for both fuel and timing maps).

By the way, you ALWAYS return phone calls....

I appreciate your advice.

Thumbs up For the super performing 996TT there is only one place to go.

Suman,

You have a very high performance car and are at a crossroads.
The best bet for you is to call Todd @ Protomotive and discuss your needs.
He uses "real" Garrats GT30's, and 35's (ala Markski, VRAlex and several others), thusly to utilize the Garrats as intended you need custom fab on the header side (ala Proto custom fabbed headers), and custom
exhuast (ala Proto custom exhuast), as well as plumb in water cooling (maybe you already have that). And as long as you are at it why not throw some custom ground cams in the mix and really make it interesting. but most importantly, someone who
not only understands how these turbos work but also understands the fueling, air flow, build specs, etc.
and programming and can DO IT inhouse!

It must be nice to be able to use all that power!!! I'm speaking out of envy as we're in the midst of a bit of speed lock-down here in the South Bay (by SF). I've felt the presence of the special CHP anti-speeding task force. With the lidar they use, there are not many counter-measures but go slow.

Nice to know someone is taking advantage of 680whp and beyond....

You should hear my car... u would not sleep for a few nights... LOL

Dont mess with the car.. u will probably sell it casue too many people got there hands in it and probably will F#CK it up....
run a AX 22 or a driftbox.. see what it does.... if its not enough then another 100 HP will not be either...
doing a gt35 type of turbo will require u doing MAF, fuel system, and tuning... and it means custom....

good luck
makski

Guys,
I was going to start a new thread with this, but it sounds like it might work in here...
I might be able to get a CPU with X50 mapping put into my Turbo. It's like taking the brain from a 2004 TT X50 and putting it directly into my 2001 TT. The only mods I have are an EP exhaust and EVO diverter valves, so the turbos and intercoolers are stock. I would probably gain 75hp from both the X50 and EP...do you think I would have any problems? Do I need to upgrade the turbos and intercoolers with this X50 programming? Has anyone ever done this before?
