Just ordered 60lb Injectors + 2.6" Pulley

[BlackSS]

Well I just ordered the flowmatched 60lb intectors and the 2.6" pulley from ZZP. I'm stepping up from 42.5lb injectors and a 2.8" pulley. Think I will notcie much difference? I've seen a few dyno sheets that show the car actually lost power from like 6200 and up. It lost 12.5hp and 12.5tq. The dynos I looked at where on tunetimeperformance.com.

What do you guys think? I'm kinda wishing I didn't order the pulley now but ohwell.

ya going to sell the 42.5's and the pulley, if so how much?

the s/c is creating much much more heat with the smaller pulley and isnt in its efficiency range. so its trying to move all this air and doing a crap job at it so the HP curve tails off, but you still make more power than with the 2.8" and 42lbs

The 2.6", with few exceptions, has the fastest 1/4 mile times.

However, the tuning from a 2.8 and 42's to a 2.6 and 60's is not the same, and is 'harder' to tune the 60's than the 42's...

I wouldn't be suprised to see it loose a TOUCH of top end with the 2.6 though. Nor would I be suprised to learn that the dyno you saw was not a perfect tune either...

Ya I hope I don't loose much up top. That kinda has me scared right now lol. I'll try both pullies and see the difference. Hey Spooner do you have a base tune I could get off you. Somewhere to start off with?

Oh yeah, I have the dual pass end plate and extra cooland resivior too to help with the extra heat.
