• The site migration is complete! Hopefully everything transferred properly from the multiple decades old software we were using before. If you notice any issues please let me know, thanks! Also, I'm still working on things like chatbox, etc so hopefully those will be working in the next week or two.

Next step?

So currently trying to decide what route I should take. I'm currently on a 3.2 pulley in my gtp with supporting mods like headers intake tune ssic etc.. I'm running 17* at Wot currently and Kr free. My main question is I know my stock injectors are at there max and I plan to upgrade to the next step up. Would I be able to drop a pulley size on an ssic or would I need a stage 2 ic? Just trying to dig a little deep for some information. Right now the car is running 14.4 at the track. We're a full second slower up here in mile high so people don't get confused. Thanks guys you have helped me out a ton! Shoutout to Scotty too!!

with your elevation you might be able to run a 3.1 or a 3.0 maybe. still gonna want injectors tho before hand. 3.2 is about the max for stock injectors.
 
typically a 3.2 is. but being your in thin air, a smaller pulley might fly.

id try tossing more timing at it as is too. i had a local here on a ssic and a 3.2 and got him to 18 kr free. we just stopped adding there cause it felt good. didnt want to push it to far.
 


if it was me, I would push the timing to 20, and if still knock free than try a smaller pulley. and when you drop pulley sizes, pull timing to 15*
 
I will most likely set the timing to start at 19* and see what happens. I still need to get my yella terra 1.8s installed. Trying to hit a very high 13 up here which is a challenge. Not sure if rockers alone will help increase a little power or not.
 
my mods are in my sig, ran a 3.2 im bottom swapped so at 13º wot timing, and got a best of 14.3 at sea level. i say good luck, my hopes were a 13.8, didnt happen lol

im now on a 3.4 and 16 ish wot timing now. kr free. thats as much as it will take, 18 was to much. back to the track i go soon.
 
I usually run 14.4 sometimes 14.5 when its very hot out up here at 6K feet. Not sure why my GTP is doing this well up here. When I had my 3.8 pulley I was doing 16.2 almost stock. I must be doing something right I suppose. Even if it was a 13.99 I would be happy as that's very hard up here. There's another GTP up here that has a 3.1 and a zzp s2 ic and he runs 14 flat all day long. Not sure what kind of timing he runs.
