As for C16 it is a great option for race cars, very specific fuel that likes running lean and loves timing, not for street cars application.

Sam

Yes stations are an issue for but if able to get there a great option, I would think 600 cc may cope on a V6, what are the current dutys (approx for your set up on pump)

1000's may not cost that much more if no headroom on say a 600, I would def consider a bigger injector as an option, but hell I cannot afford the kit, just am interested in the ins and outs for sure.
Understand on the tuning side of the bigger injector with limited tables avaliable for setting up delivery and decent idel etc.

C16 is pretty sweet, I was more interested on dyno numbers rather then DD running, maybe a 1/4 on C16.
meth is a good option but I dont personally like filling the tank and worrying about fail safes.

I can't wait to install one of these! Good job Sam.

Kastley85891 · 03-09-2010, 06:28 PM

^ lucky man , officially jeleous

Vegitto-kun · 03-09-2010, 06:35 PM

If you need more test subjects. (nudge nudge wink wink)

haha.

the owner of the dealership I bought my 370 might be interested in this.

he is a crazy guy

Would you consider using something like a Racelogic Vbox to do a 0-60, 0-100, 80-120 , 1/4 mile times etc for these types of upgrades. I think it would be fab to have these done for some of the turn-key packages you will be doing, so the average joe can get an idea of the improvements in performance these packages will provide.

i think not only from an interest perspective, but from a marketing perspective it might make some sense. I know id love to know!

We get asked those questions all the time and i think you should do it, maybe next time when we 're on the track testing .

Yes Different maps for different stages, supporting mods and octane levels. As for altitude concerns you should have none.. for a simple reaseon

- We are tuning via mass air flow sensors, maf sensor measures the amount of air entering the engine and the ecu adjust accordingly so whether you are at sea level or 5000 feet the ecu will always adjust to reach its air fuel ratio targets .

Sam

So do we lose power in the higher altitudes or does the ecu adjust and we stay the same?

Kastley85891 · 03-09-2010, 11:06 PM

The air at altitude is less dense , so is less powerfull.
Any FI system will have to work harder to meet the same levels of pressure in terms of boost in relation to a sea level vehicle.
The MAF Sam refered to measures the amount of the air passing through the intake/s in a V format, that is directly related to an ECU scaled table that takes that V and performs a look up / calc to see how much air actually is going in, it uses that figure to throw in the correct amount of fuel to meet the fueling targets.
Thats it in a nutshell, but to meet fuel targets accurately there is a lot more then MAF V / air flow alone.

The only system that have been installed and tuned successfully on a VQ37VHR is the HKS f-con v pro and it was done by us .We have tuned a twin turbo g37 with factory ecu to about 600 whp turned around install the stand alone and tuned the car to got the same results with spending a lot more time and effort

The flash is the best option tight now it does make sense to do anything else

Numbers are looking good GTM.

What i meant is that our real world abuse/track testing is more comprehensive then doing burnout and drifting the car in a parking lot.

If you do a little more research about the TUV approval you will get an idea about what we have to do in regards of testing to obtain that certificate .

Carb approval is going well, so far so good .

Z eliminator · 03-10-2010, 08:14 AM

I will assure you that i will post the 1/4 mile times when i get the GTM SC installed on my 370. Im looking forward to a nice 11.7, 1/4 mile time.

Sam any luck with the Torque Converter for my car ?

What kinda trap speeds do you think you'll be hitting?

Gmendez · 03-10-2010, 12:26 PM

Sam, what clutch/PP upgrade are you recommending with this kit?
