So I fixed some plug fouling problems.....
drove to the track (still breaking in motor :P ) Longest drive Ive ever had the car on....by far. About 50 miles.
Get there, Find out my hub spacers dont fit (too big for my tiny 5x100 pattern). So that means no slicks
I call my friend (bansheenut) and have him bring his drag radials. I run them @ 13-14psi.
I had a lot of drama getting the car to the staging lines (vacuum cap blew off on freeway and I didnt notice till I drove into the staging lanes, shifter linkage messed up 2nd time I got into staging but I was able to push it back together :P
Never done a burnout before, but these were drag radials so I wanted to warm them up. I was basically letting off right as they started spinning so I didnt get much of a burnout my first try. 2nd try I did but it didnt help.
I just sat at the line my first run then took off. I really wish I had the right spacers cause I needed my slicks.
1st gear = no traction. so after i hit the limiter I go into 2nd. hit the limiter in 2nd gear (tires spinning)
Ive never really driven this car before so I just automatically shifted into 3rd even though my car is still traveling really slow (no traction in 1st or 2nd = not moving fast yet).
3rd gear bogs bad. I didnt datalog but I think rpms dropped to maybe 2800 rpms which is not helpful for going fast. I do get traction though ....well until the turbo spools again. Not sure if staying in 2nd spinning tires longer would have helped. Like I said, I have no practice racing the car. Rather just run slicks and not worry so much.
RPMS get up to 3200ish and then the party starts again. Hit limiter in 3rd, shift to 4th, zoom.
2nd run was very similar except I almost went into the wall in 3rd gear when the turbo spooled after the same stupid bog.
I forgot my helmet so they let me run 1 more time and then finally made me go home.
Remember I am @ 4400 feet elevation so the car is a lot slower up hear. SRT-4's only trap about 95mph on an excellent run.
I need to find the right spacers and then I think with traction in at least 2nd gear, I wont bog 3rd and my traps should improve a lot(obviously E.T.'s will improve).
A lot of people thought the turbo wasnt spooling (everyone who talked to me, friends, including the track announcer) but it was just that boost in 1st and 2nd gear (obviously I can get boost in 3rd then) was causing me to short shift into 3rd and bog.
Transmission seems to have chewed up a bearing on my drive home so I will have to get my OBX LSD installed in another transmission.
I am not sure if I will race again with just the slicks to see how the Trap speeds improve, or if I will also install my custom intake manifold (short runner huge plenum, tested on my n/a SOHC daily driver Spirit and it was amazing). I really enjoy bench racing and then proving it so I sorta want to try them separately. I think the intake manifold will rock.
This is all on about 5.8psi boost (.4 bar). I lose about 2.2psi of atmosphere up here so my car should behave more like 7.8psi @ sea level.
Notice I pick up 28mph on the top end with only 5.5 psi boost wee. Probably some of that huge increase is the 3rd gear bog. When my spirit was turbocharged I didnt have traction problems and my 1/8th mile trap was 82 on 5.8psi (only picked up 19mph) so my benchracing tells me There is plenty left in this setup without using 35psi boost :P
I really want mid/low 12's on .4 bar (5.8psi) @ high elevation. Flying to see my parents so no sea level passes this year. I think I would pick up 4-5mph down there + my traps would go up just from not bogging 3rd if I had my slicks on.
