Different break in tune... I can take it to 6500 rpms now, and it is running a 10.6 afr, not the 10.1 it was on... still only 12 degrees of timing...

car made 670/680... Still SOOO neutered, compared to what it will be....

 

do you have the IRS still? any weight reduction?

 

nice! any video? i have never gotten to run a liter bike before. have a rew runs planned with a buddies R1 once the winter ends. I have run 600's and they are not in the ball park.

 

Got my car weighed at the local track (speedworlddragstrip), and with me in it, it weighed 3650... I weigh 180 so we're looking at a 3470 weight, with a full tank...

Only weight reduction is my PSR Tubular K Member (over 70lbs less than stock) and also my built solid axle is a lot lighter than the original IRS...

 

what tranny? built auto or t-56 or viperspec t-56?

 

Stock t56 with a 26 spline input shaft. Yeah, it's on its way out. Over 600 rwtq at just 3k rpms is not very friendly to our trannies...

 

what makes you think it is on its way out? mine has been holding 820 ftlbs at 4500 rpm with no signs of quiting yet.

 

Twin screw tq hits soo much harder than the turbos do... My tranny is making all kinds of noises right now. and no, it is not low on fluid. it does not grind yet, but i know its going out...

 

ah that sucks. i know mine is just amatter of time too but for now she is hanging in there.

 

nice u def picked up a bunch of HP over ur first tune..cant wait till its goin all out
p.s not to jack ur thread but does someone know how much hp in lets say a 3400lb car would take to hang with a bike..(yes there are variables but just generally) like how much hp for a 600, 750 and 1k..
