Friend of mine was having a Dyno Day at his shop so I figured I would put the car on the rollers and see what it would do. I do all street tuning so I didn't know what it would make.

Very simple combo. 100% Stock Motor and Trans, Hellion Twin Kit, Fore Fuel System, ID1000's, E85, 100% Built and Tuned by me.



Here is the car.

The engine

The Dyno Sheet

Graph is wastegate spring only, 9 psi, then 10-10.5 psi. Very conservative timing and stopped the pull early at 6800 RPM's.

And a video of the dyno from last night. My wife was a little excited at the end. LOL

Thanks. It has a Lethal 3" O/R Stainless X Pipe and Magnaflow Competition 3" Stainless Cat Back. I also have 3" Stainless Steel Dynomax Race Bullet's where the resonators are.

Did the race bullets tone it down a lot? Do you have a before and after?

I don't have any before and after videos, but with the 3" over axle pipes, there was a drone that was present and I didn't care for it at all. The race bullets were perfect and toned it down to exactly what I hoped it would sound like.

Ok cool I will have to pick up a set for the v6 then. Accelerating at 2,000-2,500 interior is LOUD. Not much if any drone though.

what size are the front rims? I kinda like that look and also seems practical vs. the 4.5 inch rims. and wat tires did u opt for both front and rear?

thing looks badass. TQ seems to be a little low. any reason for that?

Awesome stuff. Nice work!
Thank you.

You will love the sound. Tones it down just a bit and sounds much smoother.

Very Nice!

What's it run at the track?
Haven't had it out in a few years. Tried on 20" street tires on 6 psi and only managed a 2.0 60 ft and went 11.3 @ 130 MPH. I am going to put a converter and 2 step in and go back and turn it up some next year. I would like to get it to 9.90 range. Shouldn't be too difficult.

Yeah, great combo!

The front rims are 17X7 with 225/55/17's. They are only a few lbs heavier than the 4.5 and I feel much safer on them. The rear I now have the Mickey Thompson ET/SS 275/60/15's.

I have a very soft tune up in the car now. I am trying to keep the stock motor alive until I build a new motor. I could easily add a bunch more timing in it with the E85, but it already makes enough for my goals so no reason to kill it. When I put the new motor in it will get a more aggressive tune.

hope you have opg and timing gear/balancer
I have an ATI dampner on the car and shift at 6700. No OPG's until I build a new motor.

yea I'm in the market for some new wheels and I think I'm gonna sacrifice the little extra weight myself for the safety and drivability of the bigger rims/tire combo up front thanx
