Who do you trust more..
The good Folks @ autometer , or the GM installed factory sensor
Autometer says she is running at 215-220
laptop through the commander software says 195
Damm autometer got me all worried.

I tapped the Coolant sensor for the gauge into the heater core line return I made off the engine. I used Copper pipee and a few 90's to make it , soldered it up and painted it black.. not glamourous , but it works.. I think the copper is really conducting the heat and it's picking up heat off the motor. I trust the computer far more than a gauge.
7 hours til Dyno Time!

finally got a chance to take a test drive. Drives like ass. I hate this damn car. Anybody want a northstar fiero? anyone?  It was making a "whirring" noise too. Probably because it's ready to spin a bearing. I'm going to give it a once-over tomorrow. Maybe the intake gasket is leaking or something. I dont know. I pray it's something simple, because this car is taxing me to death. (Why can't I just DRIVE YOU!!!) |

My 88 3.8 weighed in at 2880 empty fuel, so is 110 lbs heavier. Must be that auto tranny that acounts for the weight change.

My car ate it's 255GPH Walbro Fuel pump. Had it flatbedded back to the dealership where I work and another pump is on it's way. I pulled the intake as well since the starter is starting to be tempermental , so I will have it rebuilt as well , throw my z06 injectors in and head back to the dyno. I think a lot of my fuel problems have been due to a faulty pump all along. I picked up a B&M pressure gauge for the rail and an Earls hi flow filter..Hopefully this recify's my issues...
It's an on-going battle!

I hate to admit this.. I think I killed the pump. In my eager state to ge the car running I slapped a fuel filter on it without reading what was on the side. I looked at the flow arrow and away I went. Upon closer inspection the filter has molded into it ""TO CARB"" IE it's deisgned for a Carb application..which flows the bit 6psi.. not the 43 or so Im tring to jam through it.. I think the puimp just overheated due to the restriction of the filter. The Pump will support 750hp N/A Motors or 450 Forced induction ponies.. it was basically working against itself.
Lesson learned. I will pull the tank and replace the pump thursday afternoon. This will probalby make a big difference @ the DynO!

Delco doesn't have a 255GPH Pump that I know of. The walbro 255gph pump is $50 more than a 89 turbo Ta pump and the same price as a 96 Corvette pump , neither of which flow the same Numbers... it's a no brainer. I got mine from JRP in oakville.
The injectors are being cleaned as we speak. Im going to get a good tune on them , then maybe swap to the z06 injectors I have and see if I can't find a few more ponies. Due to my freeflowing (almost too good) exhaust my car is really drinking back the fuel, thank god for wideband tuning. Im not going into my Dyno numbers yet , but I am putting down more torque than any 5spd N* car I have seen Dyno'd. Most Guys are in the 245-250 range and with a shitty tune I am above that considerably.
Then comes the Nitrous.... 400 @ the wheels is the goal!

You mean LPH? http://www.nolimitmotorsport.com/walbro/255gph would be like a fountain pump... I don't remember what the corvette ac delco's are, but they're probably not that high. I think it's like 150l/hr, which is good for 400hp. They're made to last for the life of the car though, which is good because changing FPs sucks. |

No , it's 255GPH pump as listed by Walbro on their site and used by many!
Well , it's not the pump. I pulled the tank tonight , tested the pump it works fine. Tested both right @ the pump and at the harness connector , both times pump worked fine. The ECM when connected to the laptop says the pump is working fine.
Driving @ 70mph on QEW the car just died... and hasn't lived since.
