Back to the track tonight... some 15psi tuning runs with the new cams. We'll see if I can beat the best 15psi run for the car so far... 12.114 @ 112.34

Good luck!!!
Good luck! :thumb:
Any conclusion on the shift fork pads?
Quiet for a friday night... could got a lotta runs in...
OK, some 15psi runs with the new cams straight up... spun hard in 1st and short shifted 2nd each run.
I was reeling in this Nova...
Me ................. Nova
R/T: .210 ................. .130
60': 1.819 ................. 1.684
330': 5.207 ................. 4.772
1/8ET: 7.941 ................. 7.438
1/8mph: 91.33 ................. 91.99

1/8mph: 91.49
1000'ET: 10.255
1/4ET: 12.223
1/4mph: 117.63 (best mph on 15psi for this setup)
^^^^ looks like a bracket car with way too much mph :D
Played with the cams a little bit...
R/T: .260
60': 1.866 < worse 60' than last run by .059
330': 5.187 < better 330' by .024 so combined about .083 better by this point
1/8ET: 8.558 < DOH! Missed 3rd, hard to stock spinning thu 2nd :o
1/8mph: 66.50
1000'ET: 12.148
1/4ET: 15.723
1/4mph: 60.38
Noticed some smoke from turbo, looks like there is a leak from the oil return line... called it a night.
Shift fork pads seem ok so far.. some trans issue still, dont think its the forks, gotta granny shift 3rd or it wont hit :(
Dude... You know you need an 11.8 for the Quick 8 Bump Spot:eyebrows: Turn up the boost already:p How much air is in those slicks?
LOL.. tuning cams at 15psi then upping the boost... oh, and somewhere finding traction?
Slicks were at 10psi...
less air in the slicks, a switch to lower the boost in 1st or 2nd gear and more boost in 3-5 and youll be golden.
oh yeah and find that shifting issue.
where did you put the brass pads? every shift fork or just some of them?
Brian
Yeah, I'll definitely try lower... they look pretty flat on this heavy car! The slicks are also pretty old too.
This is on 15psi, cant make the boost go lower...
Brass on both the 1-2 and 3-4, plastic on 5th
Every trip to the track is a learning experience, aint' it?. Glad you got her out man! Nice work!
Thanks it was good to get out! I really really want to turn up the boost but need some traction first...
Yes it is... apparently the turbo is not draining too well with 80-100psi oil pressure at startup? Gonna work on drainagle a bit today.
restrictor before turbo?
I really dont like that idea... cuz oil pressure goes down once warm.
I'm going to do some porting in the custom return line fittings first. :thumb:
or don't boost it cold :D
LOL, yeah that too.... but it idles at 90psi cold.
I'm not used to the 2.4L oiling system yet, with the new cams at idle, warm, it throttles between 20psi and 40psi
mine is 60-70 cold (70* ambient) and 30 warmed with 15w-40
In all fairness I haven't been able to beat on it enough to find problems like that due to clutch issues.
Sounds similar...
So far I found that the oil return to the pan is submerged a little when the front of the car is on stands (like it was when I put the new cams in and ran it for a while) and that also means that oil might be standing up against the back of the pan going down the track? I race ported the oil return fittings and will see if that helps, with the car level of course.
Odd thing is it is leaking out between the CHRA and turbine housing, not the exhaust like its should?
JT,
Are you by any chance using the SRT-4 oil pump on your car?
