im still running a 1.79 60' and 1/4mile 13.7@94mph at 69* weather im still losing chet loads of topend but i got my meth kit and hoping to drop my iat's alot and get alot more timing. what do u guys think. if at washington state at 60* i ran a 12.79 with stock stall and 26x11 slicks. and with tb stall and 28x11's slicks hoosier my 60' are there just not top end im think im only running 8* of timing

 

o.t.
saw your truck thursday night, couldent miss the sound of the radix, sweet truck.

 

Something is def up... What are your IAT's like?

 

209* and had to pull some timing but i got my meth kit to install so hopefully i should 109-110mph at end of 1/4mile

 

With a 60" like that I would think so.

 

im getting frustrated about my high iat's i remember last year in march here in edinburg i ran a 13.12@102mph 60*s, and in spokane wa, i ran a 12.79@105mph with 55* weahter with the stock stall and et drags 26x10.5x16. an now that i put the tb stall and 28x10.5x15 im running slower. what the hell. i never thought my truck would run slower i mean i never had this problem till now and it sux i dont even feel like racing no more. i know now iat's are higher but before i dont think they were that high but yet never checked either any help. im mean i checked to intercooler pump by removing the cap on the container and it was circulating. and it was full.

 

and all my et 1/4mile times were with the 2.75 pulley

 

Try a MUCH larger heat exchanger, turbogibbs had a great luck with a bigger heat exchanger he was in the mid to high 20s in timing with meth and the large heat exchanger.

 

Your pulley is to small bro. Go back up to a 3.0, and run more timing.

 

u think so with the 3.0 i'll get more timing. will the pcm self adjust to the boost or what. but my thing is that i ran the 2.75 with my 12.79@105. the best i did with the tb stall and 28slicks 13.05@102 in spokane wa at 65* . and here edinburg tx a 13.59@95 at 70. so i dont know if there's something else wrong
