Go over to the alky section on the other board. Razor has a sticky on how to tune his kit. :)

Read everything and then called Julio to discuss. He says my problem is to low a stall converter (2400) with the 5931 turbo. He says I need a 2800-3000 stall converter to better match this turbo. He doubts I can tune around this and also I will cook my tranny if I keep trying to race with this combo. Steve Wood did tell me when I got this turbo I my run into a lag problem....... ...what a suprise, he was right again :rock:

So what is a good 2800 stall converter, where to buy, and what is a fair price?

A converter will help.  What is the elevation of the track you're racing at?  With a TE-44 with a precision .63 on an unopen motor and stock converter running 24 psi and 18' of timing I was farting around without warming up the tires and I was running your ET's but with 116.6 mph as the highest trap speed.  You should be able to pull fuel and add timing to help your 60ft.

Here's some real world info in regard to convertor slip percentage.

When I ran the 1/4 with my SMC setup...my car would run 11.5 at 120 consistently. Turbo is a 6262 with a 16930 AC convertor. Slip rate checks in at 10 percent.

Norbs ran a 70 P Trim with a 2800 Precision multidisc. He ran a low 10 at 134. Slip rate was 3 percent with the convertor locked.

Brandon...who's a local went 11.01 at 123 with a 6131 on pump gas at 20 psi. PTC off the shelf 2800 NL convertor. Slip rate was 8 percent.

My own car is a pig out of the hole with Erics low gear fueling and timing on the default settings. Pull the full 20 percent low gear fuel out of it and add 3.5 degrees low gear timing to it...and all hell breaks loose.

One of my imaginary friends from Canada got a dandy new converter from David H. He sez it works GREAT!

Something like this might work for you. I would find a lopo converter to send in as a core or just pay the $80 as the d5 if you have it can be redone. Or you might ask around at your track to see who does converters local to you. Converter might not be much cheaper but shipping is expensive. Plus if you need it restalled or something the local guy would probably hook you up if you bought it from them.

talked to the local guy about a re-stall, he wanted $300 plus shipping both ways  :rolleyes; Going to keep looking and see what my best off the shelf option is. I gotta believe there is a good 2800 stall option out there that will work for me at a good price. Its not a hard core race car, I just want a better launch but still keep descent drivability as that is 95% of what the car see's.

appreciate all the help  :cheers:
