9.55" crank pulley swap
What kind of HP gains can I expect with an Inovators West balancer w/ 9.55" pulley and Lingenfelter CAI? using an sct x3 93 octane tune.
Thanks in advance. |

I went from 500rwhp to 552rwhp with just the 8.66. "No tune". I have a 9.5 pulley also, but am waiting till spring to install it, and get a tune.

cool, have you driven it yet to "feel" the difference? and are you using the sct x3 tuner ? I went with the x3 and 9.55" pulley with Lingenfelter CAI....so did you get it tuned for 93 or 100+ octane?

Yes, using the sct x3 and....it's a big time difference in how it feels and drives now. If people think the tires suck stock, start modifying your z and you'll see how useless they really are. We only have 91 here so that's what it's tuned for.

well that sould literall be around 590-600hp manual and 560-570 auto that is 13spi with a cold air. I know in testing on a manual they hit 575 with the rotofab intake 8.6 lower pulley on the stock tune with octane. I am pretty sure I have seen lingenfelter cars in the 580-600hp range. they use the 2.55 upper but that is the same overdrive as the 9.55 lower.

Well got her back today.....HOLY S$*%....amazing what a little boost will do. I am now pushing over the stock boost limit and she kicks out quit easily..so not sure exactly what my max boost levels are yet. I had to light them up at a stop light just to get some stick to test it. (3 deg F here tonight) ..but...Can definitely feel the gains. requesting the new 9.55" pulley / CAI tune from Ted tomorrow. I think I am going to run the torco as well. I guess there is a place not far from here that does dyno testing...might look into that some day. Thanks to my friend Danny for hooking me up with a reliable, knowledgeable mechanic...I really didn't mind paying a few bucks to have this done right vs baptism by fire.

Got tune today. Loaded to sct x3. will load it to car in a couple hours. JRE recommended going w/ a 93 octane tune for this set up if not racing . will post later about how it feels and if it was successful.

Success. I'm done....yeah right.... Thats plenty of power.....almost... I was pleasantly surprised by the gains. Very noticeable. I will do some data logging so Ted can fine tune . I did have one weird incident after warming the tires( by warming I mean smoke visible from a qtr mile or so. Hey, it's 10 degrees here so i had no option if I wanted some bite)...anyway....I got a MAF sensor code after my 0-80 run as I was stoping at the stop sign.... and it reduced my power to just enough to crawl home.........had I not had my sct x3 with me to clear the DTC's...It would have been a slow drive home. Once cleared, I ran hard a few more times from 0-100 or so with no codes or problems..not sure what to think of that incident. So to sum it up....8-10%(ballpark guess) power gains are very noticeable! Spring can't come soon enough..
