Only ran a couple of times tonight.

My brand new PI spragless convertor is already broken. :mad: I only had 30 miles and 4 4wd launches on it. :shrug:


7.35 @ 94 1.66 60ft

7.4 @ 96 1.80 60ft.

Right after the last pass the truck wouldnt build any boost will sitting still.



Still a hell of alot of fuel left over.....I think i might have to add another stage.

I'll have it right for next weekend!

Thanks Greg!

If i could of gotten my 60ft down some down on my last pass.... i might of seen a 7.1 -7.2 which would probably put me somewhere around a 11.2 in the 1/4 mile.

Also bottle pressures were only around 800 psi. I need a bottle heater. Hopefully i will get some more track time soon and keep steeping up the jet sizes.....I have a feeling that the ts 2 stage kit isnt going to be enough.

It's not a "sprag problem", it is a spragless convertor. A sprag is basically a 1 way clutch in the normal style convertor but it has problems when a vehice loses and regains traction. Once damaged it will cause your 60' times to be all over the place.

once it's broken you can't spool up... i've broken way to many converters so believe me i know the feeling.... and i haven't had any good luck with the spragless yet, been through 2 very quickly.... but too, i've talked to a couple people that are running the spragless and are having no issues what so ever..... i think Brian and I are getting a bad batch
