Not with 12.7:1 comp. I run 100 oct. But the timing is not advanced anymore than a pump gas setup. 36 degrees.

Just opened the cutout

Was that on Mustang dyno or Dynojet?

 

Can you give the specs of the cam? I always like to know those. If it were my car, I'd probably retard the timing and drive it on the street a lot. Ever hear of Indiana Core, Inc there in Corydon? I bought a 6.0 iron shortblock there for my LS1 turbo project for $350. Got the exhaust manifolds, 2 knock sensors, 2 covers, and balancer all included. Only reason I didn't get the valley cover was cuz he didn't have any or he would have let me have it too.

 

thats some got torque you got there lol i had a pic to describe it but i cant find it. so what she runs at the track

 

BTW, what brand of converter?

 

I know 12.7 was pushing it and didn't figure you were on pump gas, but was hoping to see it. Mine was on a dynojet.

 

What's wrong with pump gas and that compression?

 

PTC 10".

 

Detonation. I guess you can always retard the timing, but that kinda of defeats the point.

 

They really nailed it then. Cam specs secret?

 

Spec are not really secret. I just don't put them out there. Its close to a 236/242. I do drive the car on the street. I drove it to the Dyno

 

Amazingly, I run 12.5 to 1 compression with a DCR of 9.0 to 1 on pump gas all day...I have not noted any extra power raising the timing to 35-36 degree range (checked on dyno and the track)...In fact, 31-32 seems to work very well on my combo. But every combo's different and your VE numbers may be different than my LE 210 AFR's. Also, up here in Washington we only see 80's as the high temp summer months, normally. At the race track Pump 92 seems to carry the same power as race gas for my car (even with the timing jacked to take advantage). Next time I run Juice I'll see if playing with the AFR on race gas "NA" makes any noticeable difference.

 

Jimbob any times with your car, and more details on the setup? You can PM me if you want.

 

Got ya.....PM sent

 

Nice numbers.

 

Nice! A truly streetable solid. I've got a Neal Chance for my LS1 car and I hope it can really deliver the torque multiplication like your setup. on a great setup.

 

I live in Tacoma and go to bremerton to autocross and drag race. I'm going next time they are open. 13.2 @100 in the 1/8, what happened??? Did you just let off?after the 1/16.lol Know anyone around here who will rebuild a t56. I've been driving mine without 5th and 6th for 6 months now!! I just can't find a good deal. I know of t56 rebuilds down in texas, but If I can find cheaper up here, I'd rather do that.
