Title: Test and tune
Post by: larrym on July 23 2015, 08:38:32 PM
So we had a little test and tune made 1 pass on the DRs spun a little leaving at 3 psi bolted on some 9" slicks left at 8 psi dead hooked and left that was fun car has never left that hard what a riot!
Wish they had been recording times here is a shot of me warming up the slicks.

Nice shot!  What did you run?  And what drag radials were you using? :cheers:

Awesome pic!  Wait till the first time you pic up the front tires on a launch.  That's fun and scary

Cool pic. Slicks are the only way to fly. Were you able to record some data?

Not much zero knock and AFR was a little fat
To be honest I was too busy grinning to pay attention.

I record every run. When the two cars ahead of me roll into the water box I fire my car up and have the GAUGE PANEL up on PL. I hit MONITOR. I can see the gauges moving so I know PL is working. When the starter waves me in in I hit RECORD. At the end of the run I turn the corner at the top of the track and stop and save the file. I go back to the trailer and go over it.

I wish I had a mount for my laptop it would be nice to have so would a track!
This is at our local airport and we only have 1 race weekend  :(  with 2 test and tunes.
The closest track is on the main land 4 hours each way with $300.00 in Ferries in the middle.
We do have a short 350' track a couple hours away and I do go to it on occasion.
Its kind of hocky its typically used as an oval for stock cars they have extended the straight away with a hard right at the end plus the left lane is against the wall........

They were not recording times, I missed the first test and tune they did get 60' that day but I was changing a head gasket.....

Larry...just set the laptop on the passenger seat facing you.

And put painters tape on the rear quarters to protect that pretty paint job. :)

I spray cooking oil on the rear quarters. :)

No times???

Isn't that like playing a hockey game without keeping score?

No times until the 8th I will defiantly post them up whe I get them
I'm really looking forward to this year.
The tech guys gave me a rough time about leaving my scan tool on the seat a couple years ago I was adjusting my chip in the staging lanes figured they would do the same with the laptop.

Looks like an add a bit of boost to the launch the TR6 2step is pulling 10 degrees of timing and set at 2900 rpm
I will try to launch at 3100 rpm on race day looks like there is a delay in the TR6 adding the timing back in. I will be adding a couple pounds of boost and a little timing over all too.

Larry...what did the convertor 'flash' to on the line? What were the RPM drops at the shift points?
Title: Re: Test and tune
Post by: larrym on July 25 2015, 09:22:23 PM
The converter is too tight but I don't have the time and budget to have it loosened before the races
It's up against the conveter pretty hard if I don't pull the timing with the 2 step it will push the car thru the beams at 2900 rpm.
It shifts at about 5600 and drops to about 4800.
The TR6 module gives me the ability to work around the converter with the 2 step pulling timing and limiting launch rpm.
Wait for both cars to Stage mash the brake and the gas and let it go when you see the last yellow light.
What it flashed to I'm not sure I was watching the boost gauge to see where it was at.

I pull a whack of low gear fuel and add low gear timing to get it to spool real quick. On PL you can watch the RPM's and MPH simultaneously ...and you can 'see' what the convertor flashes to at launch. 2 weeks ago I'd spool it to 2,000 RPM...and it was 'flashing' to 2,900 RPM.

You're getting a good RPM drop. :)

P.S. I leave Erics high gear timing on his default setting. I never touch it. :)

That's exactly what I do minus the cooking oil.  I save the cooking oil spray for when we go 4 wheeling.  Makes spraying the mud off a bit easier

I'm running a gen2 translator and extender chip I have to pick my timing default is 17-15
I have it set at 21-19 with my alky tune this is conservative I know but I have bumped the compression a little and it seems to like it
I moved my WB and knock gauge to the pillar so I can now see boost and o2s at the same time it could be fat on the launch too alky starts spraying at 5 psi and I was leaving at 8psi
5psi turn on works good on the street to eliminate transitional knock it could be to soon at the track

My buddies use the clear 3m tape for their quarters my paint is shit and I wear the rubber spray like a badge of honor 😋

Post by: Scoobum on July 26 2015, 09:22:50 PM
I had my alky coming on at 12-13 PSI. I'd run the 02's in low/high gear in the 750's...and add 4-6 degrees low gear timing over Erics default setting. High gear timing I left alone.

I'm with you Larry, for what tires cost, they can do double duty.
