Blown 4.6!!!

[GitDat]

ahh.. that explains that insane power My A/F is doesn't get higher than 11.5 on my graph.

Whoa, holy crap.

Word of advice............leave your heads stock with that little 1.7.

 

[DeadLurker]

wow that definitely is lean....at no rpm is it safe.

Yes it was scary. Should've been there when it blew.

Anyway, when I talked to Tim (T&J) he said that a new cam (don't know which one), lower compression pistons, and maybe 10-12 psi should do the trick.

All I want is 450hp at the wheel. Anymore, then I'll probably have to change transmission.

Hew Screwed2V, why do you say that I should stay with stock heads? Just wondering what your thoughts were. Mine was the same, but did you see what the TEA ported heads did? It made 400 at the wheel without the KB.

Let me rephrase. If you get ported heads don't go too far. I have race ported heads on my car from a previous centrifugal combo and we put the 1.7 on the car with the 2 3/8" pulley and it just can't supply the motor with the air it wants. We're only getting 9 psi out of it instead of the 14 psi the pulley is designed to make. The little blower just runs out of steam. Now, a 2.2 on a car with heads like mine would be wicked but I didn't want to wait 'til 2010 on it to come out.

WOW!!! I don't know how I missed this thread! I guess I was away from my computer while at Chicago. Anyway, I'm back home and I'm very sorry for what happen to you motor. That is a scary story! I just oredered the 10 psi pulley on Friday...and after reading your thread I'm seriously re-considering installing the 10 psi pulley.

Safe tune or not, 400+RWHP on a stock bottom end isn't going to last forever.

If I were you I would go with VT or SHM

I think he already made a decision but why shouldn't he go with a T&J motor?

Nothing wrong with a T&J motor, I personally just wouldn't go with one. Jim probably would "forget" a wrench in it or something.

Jim? He's at VT.

Did Tim fix this supposed mistake? If so who really cares, we cant all be perfect as you.

What are you talking about? Use quotes when you direct a post to someone.

 

[neoclasiccl]

Monkie is probably talking about Tim or "Jeff" ?

Jeff is the motor builder and I have watched him build 4 engines and trust me his is the man. He is so anal about checking everything 3 or 4 times during the assembly you can't go wrong with their motors

 

[Monkie]

Oh, Tim...thats who I was thinking of!

Tim is the dyno tuner. the wrench monkies are Andy and Jeff.

 

[GinoGT]

I was talking about 2V engines; no forged crank.

bump..

I know you've already made your decision, but if it doesn't work out, Steen Racing is a lot closer to you and they build a lot of motors. I had mine built there and its solid as a rock. http://www.steenracing.com
