With the timing out of it that could put you at 125 on motor, and spraying after the 60 is worth at least 1 maybe 2 mph. There is 9 mph.

With a 1.44 60ft it should have been a 9 sec pass. Im starting to believe this converter is just to loose

That's a lot to ask from a 4l60. It could be the tranny slipping and not the converter. Who built it?

A buddy of mine built it here in Missouri

Try a set of 28" tires and leaving on n20. I used to run 3.42's with 28x10" slicks and a 150 shot would take the car from 11.30@119mph N/A to 10.30@130mph all day.sounds like your converter needs to be adjusted also but if your not using the n20 in the first 60' then your never going to pickup et and mph like it should.

Ok thanks for the advice

Even though he is not spraying the 1st 60ft his mph should still pick up more than just 2-3 mph. The ET might not be a big difference but the mph should raise up more

When we went out and logged and tuned the car on the street AFR was 12.0-13.1. Of course 13.5-13.1 on the hit since he is supplying fuel off the rail. When Brendon was at the track he was seeing richer AFRs. My suggestion Brendon would to pull the fuel jet down one and we can log and try it again.

I always like 12.5 AVG AFR on N2o.

Few more details.

Right after the 1-2 shift i see a max slip of 2,597 rpms and on the 2-3 2,984 rpms

Right before the 1-2 it was 867 and 750 before the 2-3
1-2 shift at 7,136
2-3 shift at 7,089

i got a 2010 ls3 camaro. cam only spraying i was mph 118 n/a . on a 125shot i was mph 129-131. if that helps u . kinda expect what u might gain. i was on street tires also. r u sure ur got the jet in the right places. like got the n20 jet in the fuel and the fuel in the n20. it happens alot.

also i have stock clutch and it slips like crazy . so i got a progressive and ramped it in over .5 secs and it help it tons. dont slip it softens it just enuff to were my clutch can handle the tq.
might try that or like other say ur converter might be loose. im not a auto guy so i dont want to pretent to tell u anything. u might be getting close on fuel pump aswell if ur h/c/i on a 150. but i would think ur fine but might check that aswell.

Pump should be fine it's a 255. The jets are definitely in the right spot and not mixed up. I always triple check that when I put them in lol

I plan on calling Yank to see what advice they have and see if they think im "blowing through" this converter

Do you still have your free re-stall for that converter?

Other places I recommend a converter from is FTI those guys know their stuff and are very quick in getting it to you.

Coan Racing, Walker is who I deal with and is a very good guy.

I haven't talked or bought anything from Circle D but I have only hear good things about them.

I have had great results with Greg from FTI. My th350 converter is tight for the street and N/A use and really lets loose on the bottle.

Just looked at FTI converters, The look really nice for the money. I will give them a call

I would call FTI and get something custom instead of out of the book.
