340/E85/D1SC/FItech1200 big hp SB guys step inside please!
So I have a few updates
First, I want to thank PACE performance for working with me after receiving TWO defective TSP distributors in a row. Both of them had rotor's mounting base welded on pretty crooked and would wobble a whole lot when spun. After receiving the second one like that, I decided to go MSD and Pace worked with me to get an MSD right out to me instead.
I managed to get a few things done on the car, mainly plumbing and and mocked up the intercooler piping.
I ended up having to go with electric fans for clearance with the piping, but my friend sold me two brand new Derale 2000cfm fans for $125 that should fit right into the existing shroud that my cheap Chinese fans came in.
After all the test fitting, the one thing I didn't account for was the blower pulley being taller than the blower (which probably won't be the case when I run 12psi, but for the current pulley it is). The hood didn't clear, and I used this as an excuse to go for a EV carb hat instead to free up some power. I may cut my existing hood to clear this but for now I'll run hoodless.
I am running into some set backs:
The first, and I hate to even admit this one, but after a long 14 hour day at work I stopped by the garage at night to work on the car and decided on a whim to order a new driveshaft. My friend and I measured TWICE, but somehow in a brain fart moment I must have wrote the wrong number down (actual measurement was 49 13/16 and I wrote down 48 13/16). Needless to say, I had a beautiful $460 cromoly 3.5" driveshaft made that is now an inch too short. The tail shaft is inside the trans by 2 3/8ths of an inch. My driveshaft guy tells me the bushing is 2 1/8th deep so it may be OK. I have super stock leafs so don't know how much movement there will be. I plan to drive it down to him carefully when it's all finished (he is down the block) and have him check it out. Hopefully I don't need a new tube. DOH!
Second POSSIBLE set back is the fuel system. When I switched from an A1000 to the ProTuner 750, it didn't click with me that the 750 flows SIGNIFICANTLY more than the 1000 and that my FPR (automotive 13101) was designed for the 1000. Hopefully that regulator can flow enough to keep up.
I am also a little worried about my mounting of the FPR, something I should have thought about more but it seemed like a good idea at the time. I know the firewall is not NHRA legal, but I only race the car once in a blue moon at track rentals with no tech. Because I needed so much room for it to be mounted with the Y block though, I have a pretty long length of hose running from the Y block to the Fitech (haven't measured but my guess is maybe 25" for one hose and 18" for the other). They both feed into the linkage side ports of the Fitech as I was told by a FItech tech that I couldn't use the built in FITECH FPR side feed. I conveniently found out later he was wrong, apparently you can use any of the 3 feeds as long as you plug the built in FItech FPR outlet to deadhead it.
Now I'm worried about two things, 1) will the length of hose be an issue with controlling fuel pressure accurately and 2) will the FPR being mounted behind the FItech with a small section of the 6AN feed hoses being run parallel with the car cause a potential fuel pressure drop on acceleration.
My friends say I'm paranoid and it wont be an issue with only 700hp or so on E85 while using such a high flowing pump but I'm just worried. If I didn't have some of these parts lying around already, I would have done the whole front end of the fuel system different in retrospect (used a multiple outlet port FPR mounted in front of the FItech to eliminate the Y block and run two 6AN lines back to the two front feeds of the FItech). At this point I doing this would be a major PITA as I am pretty sure I wouldn't have enough feed or return line slack to stretch the FPR up that far forward now.
You may be able to kind of see what I'm talking about in these pics in regards to how it is run.
