Default WooHoo!!! IT IS ALIVE!!!!!

Well, after almost a year with this thing being broken, I finally had the time to get to work on it.

I put the motor & trans in 2 weekends ago and have spent a few hours here & there trying to figure out where everything went again. I pulled the motor in May and sent it to the shop for disection. Needless to say we won't have oil starvation problems again. The new Canton pan should fix that problem for good. Throw in a 80 psi oil pump and I think we have a winner.

The gods must be smiling on me, cause it fire up on the third crank (though it was a bit out of time...it was setting at about 12 degrees) and I think I'll need to send a new data file to Eileen Formato to get the chip tweaked. The siamesed base has changed a few of the A/F settings and the idle was up at 1500 RPM.

I'll clean it up tomorrow and take some pics of the motor for you guys. The entire top-end is flat-black crinkle powder-coated. Looks a lot like the Callaway cars now.

I'm so psyched...can't wait to get it out tomorrow for a spin. Took it to the end of the block & back after a good warm-up and "accidentally" spun the tires after the turn-around. I don't think I lost anything in the rebuild. It feels stronger than before with everything the same....just siamesed the base before they stuck it on the motor.

I'll be back at the dyno to see what I gained in a month or so. Should be interesting....

Its good to here things are getting better. I just finished my latest mods it's great to get out for the first time and everything feels good :D :D :D

Joe, you sent alarm bells ringing for me in one of your earlier posts regarding oil starvation and the enevitable results. :eek: :eek: :eek:

What do you put your failure down to ? auto x or striaght line speed ?

I want to run 11's sooner or later but i am still using the std pan ( mid 12's at the moment i guess with my latest mods )

I have not noticed any drop in pressure on the std gauge during my runs.

What do you think ? Should i be looking for a better pan ?

:cheers:

Mostly I attribute the failure to too much traction. I race with slicks on the car, and I see in excess of 1.4 G's under heavy braking. I just happened to hit a turn at the right speed with the right amount of negative G's and I sucked a big air pocket into the oil pump.

I had a long conversation with a friend who races C4's in SCCA and his opinion was that it was also a problem with the oil pump. Stock pans are fine for stock pumps, but there isn't enough capacity in the pan when you go to a higher volume pump. You end up sucking all the oil into the top-end of the motor before any has made it back down to the pan.

If I were you, I'd put a new pan on it, or at the least an AccuSump to keep pressure there if you do get into trouble. The $400 the pan costs is a drop in the bucket to the $2500 I had to pay to fix the damage. I'll be adding an AccuSump to mine as well for additional insurance.

Glad to hear that it is among the living again. I can only imagine the withdrawls that you were going through.

Does this mean that you are going to drive it to the meeting on Friday?

As long as the weather cooperates with me.

This thing is WAYYY to dangerous to drive in the wet...hard enough to keep the tires planted when it's dry.

I'll see you there...

Mine is going to get mounted off the front cross-brace on the radiator side. I already have to run cooler lines to the radiator anyway, so it just means I'll need to add a "T" fitting into the lines.

If all you are doing is adding an AccuSump, you'll need to ditch the factory "heat exchanger" oil cooler to put an adaptor between the filter and the block.

As promised, here is a photo of the now completed engine bay.

I think it looks a little sinister now...



Does this look like 400 HP? :D

Joe,
YOU CHEATER!! You stole my idea! Haha, looks VERY :cool: One day, if I ever decide to build a new motor for my C4, I'm DEFINETELY going to follow in your footsteps. I like the way your motor LOOKS entirely stock...but when the tires hit the ground...it's quite a performer. :cheers: Let us know what the new #'s are with that siamesed base. :yesnod:
