11 at tq peak, 18 at 6k. It spools up about 1000 rpms later on the dyno vs on the street so the timing was actually 13 at tq peak.

Id be happy if i spun a bearing. Atleast the block is salvagable then. If i have a catastrophioc failure and the rod breaks ill have to get alot of ****. Might break teh block might hit the valves. Definatly not pretty.

And you know the #1 cause of rod bearing failure is det. so either way, it can be catastrophic if you spin on. Anyways, again Jeremy, that's some nice #s.

My biggest problem was I kept spinning the ET streets on the dyno.


I highly doubt that was actually a problem,im not bashing your results so don t take this the wrong way,but I would really like to see a car under 1000rwhp spinning the tires on a dyno if it was strapped down correctly.There seems to be a recent out break of cars spinning on the dyno,when I have personally only seen 1 car do it and that was our shop car(speed inc)on a 17"dr,and the fix was to simply tighten down the straps,we havent seen this problem on any other car we have dyno'd including INTMD8's tt lt1 car 850rwhp850tq or my tt mustang 1020rwhp 873rwtq.I think it was more than likley all it was ,was your tires growing and slightly rubbing the car somewhere,that being said you have the first rear mount turbo kit that has actually impressed me congrats

The only car i have seen spining the tires on the dyno and two people had to sit in the back lid was a Twin Turbo Viper that made 1200rwhp+ 1200rwtq+. I dont know the exact numbers because the dyno couldnt read higher than 1200. My friends 900rwhp viper didnt spin the tires on the dyno.

see plenty of lower hp cars do it...my cousins stalled chevelle did it

And btw my rear mount setup went over 700 with 14 psi an a gt70, theres some of us out there who did it right. Zombie keeps raising the bar at the track too.

danimal it is slip, the dyno operator checked the gear ratio and it was quite noticeable and wasn't just tire growth.

I don't believe that the car was strapped down as good as it should have been which is what led to the slip.

It will have to be street wars. I've got an alignment issue with the rear end. Either i've got a bad bushing or one of the tubes is tweaked. The drivers side is 1/4 closer to the front tire than the passanger side is. I guess that explains my slight pull to the right.

My drivers side ET street is junk now due to the alignment

your bottom end wont last much more than a few thousand miles with that much boost. also the cam is not good at all for a turbo motor you could build a lot more boost with a different cam imho. anyway great numbers for the setup!

Dug only spun a bearing because his alky kit malfunctined. I believe it happend when he was handing trent his *** on the F4i. and that 370's gonna be a monster when he gets the bugs out.
