Definitely stopping at the 125's... LOL! Apparently fuel becomes an issue with the 150's... so I think we'll just have to make do with the 125's...

What about the fuel? Have to change the fuel pump? What about your drive train, Lideo or MRT say anything about that. Is a girdle in your future? Or did they say it wasn't necessary. The auto absorbs a lot of it.

scrming

Nope... stock fuel pump... although we played around with the fuel jets to get the A/F in the ballpark... Lidio fine tuned the A/F in my tune... Both Lidio and Scott feel the 7.5 is going to hold up for us with automatics!!! You just can punish the rear end like a manual can! LOL!

Scrming, good job on those torque numbers. Are you saying that for us manuels that plan on putting power adders on will have to get 8.5 rear to hold under all that pressure? How much pressure do you think the 7.5 can hold on a stick, and oh can you post a link of a 8.5 rear b/c i'm not certain if you guys are talkn about replacing the whole rear axle or what.

scrming

we're talking the whole rear end when we say 8.8"... we mean differential, axles, etc... I don't know the price but for some reason $1,800 stick in my head... LOL!

As far as how much the 7.5 can take with a manual... I'm not certain... and while Powerhouse busted there 7.5 on a couple of occasions they were VERY ABUSIVE to the poor thing! LOL! They basically had their Nitrous setup to come on a part throttle so they were launching WHILE THEY WERE SPRAYING! LOL! And they were dumping the clutch at 5500+ RPM! Guess we'll need to wait untl one to the manual guys starts pounding on their 7.5! LOL!

Might as well stay with the 7.5" until you break it right?

If it ain't broke, don't fix it.

rygenstormlocke

My thoughts exactly. If I break it, then that means I am pushing some serious power and I'd be more than happy to replace it at that point. LOL.
