I've never posted on this forum before, so I thought this would be a good first...just incase you guys didnt know, we tune Mitsu's. Infact, we've been tuning them for quite sometime with much success. At any rate, we just wanted to let you know we are here for all your parts and tuning needs. On a side note, for anyone that wants to see any "proof" of our ability to make raw power with the 4G63, I'll leave you with these links to this dyno session and graph from about a week ago(they are being temporarily hosted on a few gadsm members websites as our admin has been very slow as of late to update our new site)

For anyone thats interested, the car is using a STOCK fuel system, just walboro 255, a AFPR and 650's (as basic as you can get), STOCK ECU, STOCK throttlebody, stock ignition. The car made 580whp on race gas, detuned. It can and will make more, but were reasonable sure were at the limits of the fuel setup. This car is in full street trim, and is living proof that you dont need to go overkill to get good results. Look for it on the streets, it's out lurking every now and then Now our drag AWD DSM, well look for it at NDRA street tire class...

 

So you guys build drag cars?

 

Nice numbers, full street trim!

 

We can build whatever is asked, from street car, to all out drag. We get requests all the time for different stuff, n the end, it's all about what you want from the car.

 

What was the duty cycle of these 650cc at the 580whp run? That is VERY brave to run 580whp on 650cc, and a Walbro. Both were maxxed out

I'm sure they were. George (Twisted) even admits they are at the limits of the fuel system, but that is still very impressive.

Nice work Twisted

I am a little biased though, there are a few Enthusiasts Auto parts on the FWD and the drag car.

 

Nice numbers twisted. I have seen the car run before the new setup and it was just plain sick. I can't wait to see it run now.

 

When I say fuel system was maxed out, I dont mean the injectors. The injectors were at 90% duty (yes, 70% is where you REALLY wanna be, but its still not at capacity) at the top of the powerband. If you keep the fuel pressure at a reasonable level, the spray pattern on the injectors will not change becuase your are trying to force more fuel out of it. The fuel pump and lines are pretty much maxed out....but not completely. The fuel pressure did not drop at 8k in 4th gear. Contrary to what many believe, you dont need to have the biggest of everything to make good power. We've been running fast times at the track for a long time with basic setups, that make more power than other cars that just slapped on a big turbo and big fuel system and hoped for the best. It's all in your tuning, and how familiar you are with the vehicle and its limits. Like I said, I could have made more, ALOT more, but just didnt wanna push on the rods.
