Well guys, in light of everyone else's threads of tracks opening, tomorrow night's the night for the wednesday drags at Sac Raceway! I'm headed there in hopes of sub-15's with a known good trans. I've heard talk of a project car out there, but I'll leave that for him to post.

Anyone else? Gates open at 4.

I will definitely be down in a few weeks or so, as soon as I get used to the car that I will have after Saturday :)

I don't see no stinking project car........ unless you are talking about a 1981 242t with a 90+b230ft and it will be there tonight I need to see what it runs before i crank up the boost!

well we flogged the frankenvolvo and it is much faster than the time slips show had some minor issues that ended the night early...the water pump started leaking from the rubber gasket where it meets the head ....and the clutch cable is stretched so it needs to be replaced but all in all not to bad ........flogging the car is a good way to find the week points !!!

absolutely no traction and a missed second gear "due to clutch issues" netted a 19.2 second run....noticed the water leaking still went at it hard with a different driver and netted an 18 both times suck but the car has a lot more in it.... second driver came back from his run and said the missed second was not my fault car was shifting bad and the clutch was stinking to high heaven adjusted the clutch cable and found the plastic adjustment sleeve was stripped we were going to run it again until we noticed how bad the water pump was leaking.... better not do any permanent damage so we called it a night for frankenvolvo. the car drives like it will run at least 16's maybe even 15's more tuning time is required

we were talking about how the car was shifting and I think as well as changing the cable I'm going to drain the mtx fluid and put ATF in the m46 just doesn't sound right it hasn't since i started driving the car last weekend.

Gary had a good couple of runs in his wagon but I'll let him tell you what it ran

well I'm disappointed but it was a helluva way to shake the bugs free.:poo:

Ok guys, finally got something SOLID, for the first time in this car. 16PSI with a 16T (thanks Mike). RT of .200 to .450.
First run - 15.33 @ 90.1
Second run - 15.34 @ 89.6
Third run - 15.44 @ 88.3 with a passenger.

Sure beats what I had before, and when the turbo cam goes in things should change a lot. I have a suspicion the VX is a serious limiting factor at this point.

Gary you sure you dont have the VX cam 5 teeth advanced? NO offense but theres no reason at 16psi you shouldn't be running a solid low 14. Either your smugging 1000 lbs of coke in the trunk or something is wrong.

Yup. Cam's mounted right, belt marks are on, timing marks are on, running at 1 degree advanced right now. I should have the turbo cam on in a few weeks and get a time or two then. At least it's staging right, and I can launch it decent (though I'm still getting 2.4 60' times).

When you launch is it spinning the tires?

The consistency looks nice!

Well Im just going to say that the VX in my car went well into the low 13's, and I've seen plenty of others with similar mods that run in the low 14's.

Are you shifting at 4000 rpm? :rofl:

03-08-2007, 01:39 PM
No tire spin at all, shifting at around 5200-5400 each time. I'm letting the trans do the 1-2, I'm shifting the 2-3.

BTW Doug, you were also running a T5 with different ratios if I recall. Any idea what rear-end you had?

I'd try launching a little harder then. As in, holding the brake and getting it to boost MORE before you take off. And shift at 5400(maybe more depending on how your car pulls) out of first, the other gear changes won't make as much of a difference if they're around 5400. I'd try manually shifting, and boosting it (more?) off the line. Were you building up any boost before the launch?
gsellstr
03-08-2007, 02:02 PM
3 different launches, none really made much difference. 1st was at around 10", second at 0, 3rd at around 5-7psi. All netted similar results, with slightly faster 60' but lower top-end for some reason.

Hmm. Odd. Quite odd.

Agreed. Frustrating as well. Everything is stage 0 or stage 1 at least. No difference between stock chips and a 15G at 11psi and chipped with a fresh tranny, Fred's chips, and a 16T at 16psi, other than less pinging.

3.91's. Hold that thing all the way to limiter in each gear manually.

Yeah gary those times really don't sound right at all. I remember Juston Silva ran I think a 15.1 or 15.2 with an open stock downpipe and I think a VX cam. Stock boost and everything. Someone can chime in to the specifics of what he had when he did that run, but I remember it was almost stock. Mike (thelostartof) had very similar mods I think, 3" exhaust 15G and some bigger injectors, and he was in the low 14's. Something's very wrong on the car to be running those times.
gsellstr
03-08-2007, 04:35 PM
As I mentioned, first run before chips, more boost, but with the 3" was 15.2 @ 95. Same driving technique.

If anyone has some suggestions, I'm still open. Please don't suggest the 'stage 0' stuff, as it's already been checked. Exhaust isn't plugged, O2 isn't taken into account at WOT, fuel filter is fresh enough, both pumps are fine, no leaks in the IC, boost is finally stable at 16PSI under WOT clear to 5k+, injectors were cleaned less than 5k back, 2 different FPR's make no difference, plugs are recent as is the cap and rotor, wires (bougi's)are in fair-good shape, brakes aren't dragging, alignment's good.

throw the stock ECU back in it and 2 gallons of 100 octane.

Don't forget to blow on it like a nintendo cartridge first... Maybe throw a game genie in there too and enter the MOPOWER code.

Or throw the stock ECU and 4-bar on and run 12-13psi. I still think it's cam though. It's running out up top really bad.

I think you meant to say ICU there Doug.

Gary, anything's worth a try.
gsellstr
03-09-2007, 03:28 AM
Oh, I actually DID try the stock ICU and the times were .1 slower and it pinged the whole way down the track. Chipped ICU back in and I got the .1 back and no pinging. This was the same day in 3 consecutive runs. Shoulda put that in the previous post as well.

Hopefully you can kinda see why I'm so frickin puzzled by this.
klr142
03-09-2007, 03:43 AM
I see. That sounds pretty dangerous though, as you should in theory reset the computer and do quite a few driving cycles before actually trying to drive hard on the stock ICU. It's more aggressive with the timing, and your ECU is still thinking it's working with the chipped ECU. Gotta give it time to work it out! Still though, what the heck!? Yeah. Puzzled with good reason. Lemme drive it, I'll figure it out... Haha.

You coming out to the meet on Saturday?

Gary I am retarded.

I took the VX cam out and put the K15 in well before I went to the track. I've still seen plenty of cars go 14.0 with it, but might as well go bigger.

If you dont already have one I'd try one of john's dual pattern cams.

I've actually got a brand spankin new IPD Turbo cam sitting on the shelf waiting to go in when I do the HG and other stuff on the top-end (springs, keepers, seals, silencers, breather box, intake gasket, etc.).

I still gotta check what the diff is one of these days as well. 3.31's are probably NOT going to be the best for track stuff, and I'm wondering if that's what I've got.
