Been a while since I've been back to this board. Always something else to do. The story about the car is that I did take it to the track and it broke. Towed it home. Once apart, I found that one of the rods had the oiler hole welded in but not re-drilled and that scrapped one of the pistons and toasted the crank and rod...but only that one. The others still looked great! Long story short, we're back together, thanks to some of the good folks here on the list. Cost me a fresh uncut crank, new rod, piston and a set of bearings. I'm ready to play again.
The thing about the alcohol was my misunderstanding about the "high" vs. "lower" boost setting switch. I thought the alcohol didn't come in on the low setting, but found out after a few e-mails between us last year that it does, even on the lower boost settings.
Hey, Larry, I don't think your car has any more than about 300 miles on it since I've had it. Most of that was the drive to the track when it broke.
I'm glad to see you're still hanging out here....might you be considering getting your feet wet again?
Your daughter is almost 4 and might like to help dad with his "fast car". My kids both did at that age.
Great to hear from you!
So, the car is all back and ready to rock!?!?!
I recall you mentioning something about the oiler holes, but that baffles me. I surely didnt modify the rod as such as I bought those rods from a vendor and just installed them. Perhaps someone was trying an experiment? I could perhaps see how the piston might have gotten damaged, but I wonder why the crank got roasted if that hole was welded shut? I would have thought that having that oil hole shut would have increased oil to the bearing rather than the opposite.
Well...who knows.......But, Im sorry you had that problem. I put that car through its paces so many times (in stouter form than I shipped the car to you boost-wise....:) ) and this issue never reared its ugly head.
In any case....yes...you need to keep the alky on all the time. The controller will adjust the flow rate based on boost pressure. Have you changed the dials on the alky controller in the glovebox? If so, be careful before you turn up the boost. There really needs to be alot of alky flowing to support fueling needs of the SC61 turbo. I cant recall with 100% certainty where each of the dials was set, but if memory serves I believe the alky was set to kick on somewhere around 6-8 psi and with the pump set to ramp up as fast as possible with boost. You have to stay ahead of the boost with the alky as this turbo builds boost so fast once it reaches about 10 psi. If you can, take a pic of the dials on the alky controller and send to me and Ill see if they look about where I set them. I **think** the first dial was at around 11-12 oclock and the second dial was fully turned clockwise.
Also, the rising rate FPR will also add gasoline in conjunction with boost. If you want to run high boost, then youll need all the fuel that both systems offer. The gasoline fuel pressure under 30+ psi boost should be 110-120 psi if memory serves and the alky pressure at full boogie will be about 170 psi. But, I ran 35 psi on the street with things set the way they were and fueling was fine. To get 35 psi boost, youll need to swap out the wastegate can arm insert to the shorter one. If you recall amongst all the stuff I sent with the car were a few aluminum bushings of various lengths threaded on both ends. The shorter ones give more maximum boost.
As for my soon to be 4 year daughter and cars....shes all girl! Not sure if Ill mess with cars again soon or not.....Im tempted sometimes, but the time commitment is so much that it makes me shy away as I like to have lots of free time for doing other stuff, family, etc etc. Cars are so much fun to play with....but also so all consuming!
But, I will confess that more than once Ive thought back about selling you the R/T and thinking I should have kept it! But, I know its in the best of hands now. Heck...300 miles in over 3 years means the car has had a nice long vacation.....and should be well rested for some boost :)
