YS Trim beast is running
Chris (Znines) got the Formula running this morning.
I still have to dyno tune the car early next week before I can take it out and race it...
Recap of the setup:
Vortech YS Trim, concept by Chris Sikora and Bob Kurgan
Griffin air/air frontmount intercooler
9:1 348ci by Speed Inc.
6.0 heads
Kooks 1.875>2.000 step headers
3.5 oval dual exhaust with Flowmaster race mufflers
T400
TCS 5000 stall
Moser 9", 4.11 gears
28 x 10.5 x 15 Hoosier slicks
FAST pcm system by Cartek
Custom blower bracket, alternator bracket, solid adjustable tensioner, ducting, fuel system, initial tuning by Chris and Kurt from SS Racing in Elgin Illinois (www.ssracing.net under construction) with considerable input from Bob Kurgan (NMRA Renegade veteran racer)

Re: YS Trim beast is running
John...how high are you gonna spin the motor? According to my calculations, even with your tire growing to 29 inches at speed, you will be trapping 135mph at 6450rpm with a 4.11 gear.
You will be closer to 6700rpm with 140mph speeds. I would think your combo is capable of these speeds after all the bugs are worked out. Do you plan on staying with the 4.11s? I know Mike Brown runs 3.50s in his 9-inch for this reason. No need to make the motor spin extra high with FI.

Re: YS Trim beast is running
I have a set of 3.50's and a set of 3.70's.
I am also very close to putting 29's on the car.
I'd rather put on some 29's first but I need to dyno it first and see what the converter does too.
The motor is set up to buzz to 7200 rpms.

Re: YS Trim beast is running
Awesome John. Engaged and car running all in a couple of days!! Big congrats!
Question though, would the 29's vs. the 28's affect dyno readings? If you are trying to get a great tune, wouldn't it be better to tune it in a "race ready" configuration rather than change something after the dyno?

Re: YS Trim beast is running
28's and 29's are not that big of a difference.
Keys for me are to dyno with the same gas, same plugs and same exhaust configuration.
I have a set of NGK TR8's to put into the car between now and Tuesday when we are hopefully going to dyno the car. Car already has a bellyfull of VP C16.
