I go wot at the second last amber, and let out the clutch on the last amber. I have yet to load the newest logs to my computer, but launching this way usually has it at 0-2psi. I'll post a pic if a log tonight.

 

I wonder what it would run if it had a Glide ?

8:90's 9:00's I believe if we can get him to try it, not as fun to drive as stick on street but big numbers.

Lol, never happen

 

here is a pic of boost vrs rpm during the 9.57 run:
#ad

the white is rpm, green is boost. the RED line is when i let out the clutch - 1.8psi, the very first peak on the green boost line is 16.0psi. it averages 16.3psi, but actually goes up to 17 in high gear.
A/F ratio is not on pic, but is 11.4 in first, 2nd and 3rd, but creeps to 11.8 in 4th and 5th!, I better jet it up!

Was this with the w/m?

 

yes, water/meth activated at 4 psi

 

3.73's next?

 

Ya, I'm done for season, so thats 1 of the things i need to do over winter, along with an engine plate, and deal with IAT's, they jumped up huge to the 200+ point on the 16 psi setup,The IAT's measured by the egt sensor on the orriginal dyno sheet may not be that far out to lunch after all??? I think I need bigger nozzles for the w/m, or breakdown and do some kind of intercooler. I really dont want the intercooler, as my car is already a tank at 3510lbs race weight w/ me.

 

Ya I think you've had a great season, time to set back and enjoy your new addition to the family. I'm like you I would'nt put a intercooler on it either just a little more nozzle. Don't disappear on us.

 

no worries, I'm officially a boost addict

 

Thanks for the log.

Can't read the scales though.

I was looking for time to full boost w/ start and full boost rpm.

 

Ya the log view software doesn't have the scale on the graph, only in the data box on the left, and to get specific data you click on a point in time to get all data. Kinda crappy, but it works.
It is at full boost aprox 1 second after launch from 1.8 psi, launch rpm is 4800 on 2 step. Full 16psi boost was hit at 630 during this run.
I don't think that is what your after, as i did not attempt to build boost on start line, just let it leave easy for traction. if loaded hard enough it would build full boost by about 3500 I'm sure. On the street it spools virtually instantly, as long as I don't lug the engine below 3000 when I stand on it.

 

Nice results, esp with a stick. Im putting together my ls2 with as cast l92 heads and a turbo cam right now, so your setup gives me hope, especially because I'm committed to a stick shift as well.

Difference is my car is alread heavy as shit, so once the turbo goes on, Ill be putting an IC on it... Also is fuel injected since the ls2 was stock (05 gto). Plan on putting a s475 on it, but it'll be a little while, Ive got a couple projects going all at the same time.

 

So 3k stall should be fine
Thanks

 

If I ran an auto, I'd have 32-3500 stahl in it.

 

No , you would let PTC tell you what to put in it .

 

Who's ptc, do they make clutches? Lol

 

You wish ! .... LOL

 

nice #s
