My 89 Camaro Project

[Superdave]

I set the limit to 2500 and return at 2450, it worked well as long as the back tires stuck. Once they moved the limiter stopped and i'd just spin.


I think i'm going to pull the converter and have it redone.. 4500 RPM would work well.

Joseph Upson had the same uber-rich issue with his fiero recently running 8F.

i can't remember the exact fix ATM.

i do have the 3 step rev limiter code written out and applied to a BIN, but i need to bench it first.

[Superdave]

no luck today, 2800' DA and a bog off the line kept me in the same range as last time. My best 60' was still a 2.1 on 11" wide ET streets.


I think AE and PE are overlapping, AFR drops to the 9's/10's for a split second and it's taking about 30' to recover. Tried all kinds of stuff but I need to dig deeper into the code to see what's going on.


Using the P/N rev limiter for launching worked out well but i had to drop it to 2500 RPM or else i'd burn the tires.

Nothing broke, didn't overheat, 60 mile round trip + 13 passes.. just a little over 1/2 tank used.



I have some in-car videos that i'll post up soon, there may be some on Youtube as well, not sure yet.

Time to have some fun...





15x3.5 Pro Stars with M/T Frontrunners (20 lbs each), 26x11.5x16 ET-Streets on 16x8 Steel rims. Got a great deal on the setup, only had to drive a little under 2 hours to pick them up.



I also removed the front sway bar per everyone's recommendations and removed the helper bags that were in the rear coils. Adjusted the shifter cable so it should hold 2nd gear like normal now. Also added a pin to the '7730 for fan 2, then wired that into the cluster's un-used "temp" light. light comes on at 200F now and off at 180F. Works good.

Sanded/cleaned all the cluster contacts so i don't have to beat on the dash to see my oil pressure, voltage and fuel level. Also moved the tach to a better spot.


Pretty much ready to go back out on 6/10 for another track rental, just need to address a small clearance problem with my left tailpipe.

Not that I recall...

Could be a few things. Thirdgen has reading material for days all about driveline vibes. Grab 24 Pabts Blue Ribbon and giver.

I doubt there is much of the rear bumper left as is.. lol


When you had the 700R4 in there with the 2.2 flexplate did you have any weird vibrations under load?

[Mars]

I haven't tried it on the track yet, but I removed the inside door crash bars, the bumper frame supports front and rear in my camaro. Likely cut out 150#... The rear bumper support just comes right out, and put the cover back on, looks stock. The front requires some SLIGHT bracing to keep the bumper from being pushed back at high speed, but you can gain enough with just those 3 things. The door feels like a "normal" car door now... not a super heavy Camaro door. I swiss cheesed it a little as well, but nothing major.

[Superdave]

forgot to update this thread.. I switched to manual steering and fixed a bunch of junk over the last month. Had to add a vacuum pump so i'd have brakes, etc...



I got 16 runs in today at the MFBA track rental, DA was pretty high but i managed a best of 13.94 @ 99.4 MPH.



I figured out the trans issue, the shift cable is a little out of adjustment. I was finally able to shift close to 7K. I don't think the 700R4 was happy about that but it held.

At the top of 2nd and through 3rd under load there is a very noticeable vibration. Once i let off it smooths out but it's something that i'm going to have to keep an eye on.

Got a few other things to work on, maybe a bit more weight reduction and i need to finally get my slicks mounted so i can push the 60' times down..2.15 is just pathetic. haha


Tune wise, my 33# injectors are going above 80% duty cycle.. it's time for an upgrade there too.

[Superdave]

lol, i should pimp it out. I need to soup up the power wheels jeep first though.

[Kenova]
