Only have 100 miles on it so far. Going to put on about 3K before I do anything crazy with it. What do you think the max HP I could get out of this and quarter mile? Any guesses guys?

P.S. Thanks to the fellow trucker who got me up and running on this forum!

 

Looks and sounds good Ken!

 

Nice!!!

I don't see any reason you couldn't pulley that blower down and get 650+hp out of it. With 10-12psi it should be in the 650hp range. That blower is rated at 680hp so it should be able to do it.

If you do that 11's could be there.

Sending you a PM here in a minute also.

 

Very nice Ken. It just took selling your house to light a fire under you to get it finished.

 

Very nice setup. You should have some nice track times!

 

that motor is prety, can't wait to hear what you can do with it.

i like xlr8nss's numbers, really dont know.

 

Just read that you ditched the 2 extra injectors unter the TB. Hope that the extra 4 work out the way that you want them to. Congrats on getting it running again.

Sweet setup. Its really an unsuspecting looking truck. You should get some good kills and **** off some vette owners.

 

what'd you do to fuel that much engine?

 

Hey! You're welcome!
