Building a car for the mile

[1 fast evo 2]

Mike I wouldn't worry about that clutch not holding the power, they are good for dsm's runing in the 9's in the 1/4 all day.

Notice how the folks on here always come thru in the clutch??!!  (Sorry - the Devil made me type it)

Ok enough threadjacking, back to John's TSI

[Johntsi]

Its all good, my clutch was having trouble on the dyno, wouldn't hold past 35 psi 84X AWHP, put in new discs and floaters.  If it doesn't hold at more power now it will be time for a Tilton.

[Johntsi]

Took the car to the dyno today, found the limits of e85 on my setup.  Car made 832awhp 567tq at 38-39psi and 13* of timing peak.  Air fuel in the mid to high 11s, we will go back and try again on e98 and if needed import.  Should have more room to grow with more octane.  Hitting the track next weekend!



Had I had the e98 that was in it last time it would have crushed the old numbers.  Clutch is holding so I will leave it alone until after next weeks race.

Is it E-98 because of the denatured additive or is it 2% gas?  If 98% why not just use 100% methanol which is cheaper? I realize ethanol it is not as corrosive as methanol and has more heat energy than methanol but since E-98 is not readily available I was interested in your thinking.    TIA   

[Johntsi]

Its e98 because 100% ethanol is consumable as a alcohol.  And ethanol doesn't require as much of a fuel system as methanol, I am at 86% duty cycle on 2150cc injectors right now at 50psi base fuel pressure, on methanol they would have been done long before this.  I may end up back on gas, VP import, it will pull me further back on the duty cycle and have more than enough octane.

Thanks for the information John. Will you make Speed Week this year?

[Johntsi]

1 more lb of boost 1-2* of timing e98, 864whp, ran into a issue should have it fixed and on the dyno again tomorrow.

[RansomT]

Nice!   Looks like a slight issue at the top .....

[Johntsi]

888hp 611tq

[Johntsi]

Went back to the dyno tonight and found a few interesting things, the 1.01 - 1.28 housing swap cost me 150rpmish spool but at the same boost level picked up 50whp. Onto the good stuff, car made 1033hp/658tq STD it made 1021hp 651tq uncorrected and 1007hp 641tq SAE, so no matter what way you slice it.

I left the dyno files on the computer at work so I will post them later. I cannot begin to thank my sponsors enough, Brian and Jason at Wier's automotive for all the help and place to work on the car over the years. Tom and Dave for providing me a hell of a EMS; Marco for all the help and the Manifold; Ron for years of **** talking, support and and hell of a manifold; and finally Chris, Ben and the rest of the guys at national speed for the dyno usage.

So when are you gonna quit "Dyno Racing" and put it on the Track?  8-)

Hope to start testing it at the drag strip next weekend.
