I believe its about 20 rwh for every 1psi increase so with no other mods like meth etc. I think you would see about 60 rwh.

 

Do they make smaller pulley's for all the accessories to accommodate for the overdriven crank pulley? It just seems that some thing would be spinning unnecessarily fast given the higher idle with a cam, higher redline, and a 10% increase. I'm just thinking if you are upgrading to an 8 rib anyway why not correct the issue all around... what the hell do I know though.

 

so If I do injectors and put a 2.80" pulley on I should be around 10psi? It will not require meth but would be a good idea? I have a 108.75" belt on now with going from a 3" to 2.8" require me to get a smaller pulley? I have a adjustable idler pulley.
What is the limit on IATs how hot befor I should worry? I dont think I can do meth right now.

 

Just make sure it pulls timing with higher IAT and you have nothing to worry about. I had close to 200 degree IATs at the track here last year just because the ambient temp was so high, but pulled about 10 degrees of timing to account for the heat. Never had an issue. It just makes you slower til you cool back down lol.

 

ok cool

 

Yea mine was the same way.. 80* ambient and some heat soak my IATs hit 165* at the end of the track. mine pulls about 10* at that point also.

 

Mike, are you saying "get rid of the cats" because the meth will ruin them or because the cats are a restriction?

 

Both im sure..
