Time to re-power the race car.. New goals 280mph and 2000ish HP
After running 267 mph this year on my original F1x setup, I have decided to re-power and go for the overall Corvette speed record in 2019.
Long block is out and getting upgraded. New billet crank, o-ringed heads, etc.
F1x and belt drive is out and being replaced. Not ordered yet, but I am leaning towards a 106mm single turbo up front. Car will retain the 2 stage direct port just in case!
I am thinking of running the inlet piping thru the front bumper again, air-to-water up front, radiator out back.
Staying with the manual trans for now, but we will see how it takes the power. A few small things to figure out, but it should be a fun winter getting everything put together.
We made it back from the Loring Timing Association's Harvest Event in one piece! Rain on Thursday and a heavy cross wind Saturday limited me to testing and only 3 passes but we got a lot accomplished.
When we arrived the car had zero tuning or testing on the new setup, so I spent some time with the idle and 40mph access road tuning. Once it was drive able we began testing and making small changes. I decided to skip the CO2 boost control in favor of springs only in order to limit the number of variables in the mix (coupled with my lack of experience with turbos in general!). My first guess at spring pressure netted 37 psi and the car was totally un-drive-able on the test track. I backed it down to 13 psi and made a full pass at 252 mph in the 1.5 mile. (boost did creep to 21psi on the top of the pull).
The Big Red Camaro had shown up (all the way from Cali to Maine) and they had the goal to beat our 267 mph track record. Everyone onsite seemed to enjoy the rivalry, and by Friday the Camaro, myself, and Ron Keselowski were all in the 250's.
Saturday morning was a bit windy, but we decided to up the gate springs and make a pass. It was a fairly soft pass, short shifting as the boost rolled in and caused massive tire spin. To my amazement, with a fairly slow 236 mph mile, the car motored to a 269.6 in the 1.5 mile!.. Rivalry over, we had reset our own top speed and the track record yet again. We prepped the car again, but big cross winds and then a rain squall ended the event for us. I also set a new personal record with recorded wheel spin at 230mph on Friday!
The 269 pass was at 18psi, creeping to 26. The car has a TON of speed left in it! I do have a lot of tuning left to do and a few things to change, but I couldn't be happier with the turbo setup.
All other systems worked great.. The rear mounted cooling, new air-to-water, aero, chassis, etc worked great. The new Mantic sintered iron triple disc clutch takes some getting used to, but showed zero slip in the logs. The front bumper was hastily thrown together at the last minute, so that will need some work to clean it up and fix the body gaps.
The lift has been great.. Use it at home and at the track. I dont have room for a traditional lift at home, but I have been able to do everything off the quick-jacks.
Not totally sure.. We dynod it in 2016 when I first put the car together and it spun the tires at 1100 wheel. Lots of small changes since...I am guessing we were 13-1400 at the track this year (without the bottle). (made 35 psi, but it runs a soft tune due to the length of pull.)
My best pass had some belt slip and only made 27psi and only took a 100 shot before the clutch slipped trying to spray the second 200 shot.. Car easily had 270 in it that day
I have considered it (fuel system is still in question).. I am pre-wired for 2 sets of injectors.. My fear is that I would still need the air-to-water to keep IAT's down, at which point I would rather just keep the simplicity and consistency of the C-16.
I am eyeing the area where the mufflers reside for either the radiator ,or a square fuel cell. An off the shelf cell would make fuel pumps and plumbing much easier in the future.
The Fore system I have is rated for 2000.. Not sure if we will try it or not
I have an 8 gallon cell in the back and setting up the fuel line/pump is certainly a bit easier than dealing with OEM tanks.
I'm using a Waterman cable and rear mount pump with M1 and no I/C. But my car is only a drag car - 1/8 & occasionally 1/4 mile. No water in the block. You probably can't do that.

I would imagine I'd need a new block every pass! We make a ton of heat in the last half mile.
