Eforce.. results of pulley change
I spent the day yesterday doing a few upgrades. We switched to ID850 injectors, 3.25 pulley and modified the fuel line to feed the rails properly from the rear to prevent any possiblilty of starving the last cylinders to get fuel in the stock setup.
Thanks to my man Seth at Federal for many hours spent to get the tuning right with great power and my priority, safety for the motor. We got 619 rwhp and 650 lbs of torque but backed it off a bit in the end to be safe. Idle and driveability are as good as stock. Now if I can figure out the shift points with my 17" tires I should get some great runs at the track this summer!

Its a blast to drive.
Stock cam. Engine has never been opened. I'm pretty sure there is no belt slip because each pull had identical boost line. Its making 12lbs at peak HP and just like my other pulley it pops up a pound just after the power starts falling. I believe this has something to do with the runner design, but I will rarely if every run over 6k. Just no need to.

Well, I was going to get one of these:
but ANY contact with the SC will screw up $1500 worth of air brush work.

Keep in mind that dyno chart is from a dynapak. I'm not sure but I beleive they read a bit higher because of having the rear wheels off. I dont really care about the number, want to see the gains from any changes. This change gave me 45rwhp and 80 lbs torque !!

Nice liner but I am just not into that stuff. I try and keep my car looking as bone stock as possible. Just a thing I have.

Ain't that the truth. A curse maybe. I went to try the car last night but I have to go to my regular track when I get a chance. The place I went is crap with 0 track prep and it was too cold which made things worse. More for the kids to play with there civics.
anyways I really went to do some logs and work on my shift point issue. Still banging the limiter and with a 2.3 60ft, I managed an 11.8 so its coming together. With the 1.7 60ft I was getting on a prepped track I will get to where I want to be.

Those are some great numbers
I've had a 3.25 pulley on the shelf since I installed my blower. If I ever get everything else sorted out I'll put it on, at least for some 1/4 mile passes. Maybe I'll finally make a trip to the dyno as well.
You may find that you have to lower your shift points quite a bit to keep it off the limiter.
How much timing are you running?
