what are you 6 speed standard guys running in the quarter and or on the dyno! what all do you have done. and what kinda MPG's are you guys getting

 

1)with the CURRENT mods in my sig i ran a 12.9 1/4. Thats with a stock clutch that is almost gone, and a 3rd gear 4hi 5lb boosted launch. consequently i think that was the run that put my clutch in the status it is in.

2) I hit 602hp @ 3200rpm spraying nos into the intake and maxed out torque on the 1000 lp/ft dyno cause it was mostly used for rotary mazdas and other ricers.

3)and if you care i got 5th place with 64 feet in my first sled pull locally with road tires filled all the way up.

 

thats pretty quick! what company are you gonna use for the clutch upgrade? with the mods you have what mileage are you getting?

thanks for the reply

 

1)Im getting a southbend dual disc with 3600lb plate load.
2)I drive 5 hours almost every weekend, so with the Bully Dog on TOW and me runnin the speed limit... I hand calculated 23.5, with it on crazy larry and me runnin with traffic or better, i hand calculated 17-18. dont trust the overhead BTW.

 

i have ran a 14.3 with the clutch slipping on 33s now i am on 36s and get 18 hand calculated

 

Fastest hand shakers are low 12's. I think 12.2? Also you might want to consider the 3850 on the SBC. I just had mine upgraded to a 3850. Seems almost Identical to the 3600 on the pedal and a little stouter. 3600 is good to around 700hp they say.

 

I was told by Peter my 3250 would hold 650hp w/ no problem, so Id believe the 3600 will be good for more than 700hp. IMO unless you are pulling a sled Id go w/ the 3250 DD

 

The clutches are the same price and theonly thing that changes is the clutch preassure if you go bigger from what I was told. So with that in mind I figured a little extra time on the stair master might be necessary but it will hold a little more. I really dont mind the added pres. on the pedal.

But im sure if thats what Pete told ya its right but im inching closer to 700 and hopfully above I was told by the SBC tech to go to a 3850 and it would handle 50+ hooks to a sled before rebuilding!!

 

I have the SBC 3250. I had the 3600 but had some serious noises, squeals and rattle, and Peter sent me a new 3250 to replace it. The 3250 has been great, less rattle, and only squeals once in a while (3600 squealed all the time, 1st or 2nd gear launches). I ran a 15.1 on 35s with nothing but the Smarty, but wasn't very consistent. The autos run way better numbers.

 

The 3250 is now only a $150 more than the big single

 

Really? Wow Thats good to know. I guess I only thought that Cuz they charged the same to rebuild my 3600 and turn it into a 3850. That makes the 3250 look pretty appealing if your at or below ( and plan to stay there) 650 and dont wanna hook to a sled.

 

Yeah that sucks cause my OFE has been in for awhile now.

 

Im running the 3600DD and love it. My hp goal is in the 650-700 range so i think im alright. I dynoed 468/923 with the Smarty on 9, 5" exhaust and clutch.

 

I read on the TDR that Southbend came out with a lower priced DD. Anyone have info on this?

 

I had a 5 speed Dyno and quarter times in sig on 35's. An average about 19 hand cal. on 37's.
