Here is the slip from my second run of the day first one on the bottle, first run of the day was N/A a 14.3 with a slow spinning 2.1 60' time. I then decided to start on the bottle to see if I could beat my best of 13.078 I got in Chicago this year, I ended up with a 12.9 which had a 1.98 60' still kinda slow.

I then got 12.85 and another 12.92 slower 60' so I lost some off the line. I went back on the 10th after fixing a wheel bearing and also decided to get the bottle to the proper pressure... I'm running at 600 typically... Ambient temp, and it should be 900+



number 416 for proof.


Through all these runs the car was weighting in at about 3150-3175 or so.

Once I got my cousins bottle out in the sun to warm up it reached a peak of 950 PSI so I decided to run with it...

All I remember is 1st spinning shifting into second then that breaking free and then just keeping my foot into it, and I'm glad I didn't let up.

Nailed a 12.67@107 Pic of slip

When I changed from my old gen III with a 2.7” pulley over to a gen V my original plan was to start with a 3.0” pulley. However with my new belt wrap system, the 2.7” Pulley was only pulley I could run with the belt I had on hand. I also don’t have a 2.8 or 2.9 pulley to work with.

However I feel the 2.7” pulley maybe too small of a pulley to run with the expectations I am trying to get out of my tune.

I am currently running 11.8 AFR with 17* to 23* timing at WOT on 93 octane. I am seeing around 13.0 to 14.5 PSI at WOT (according to the stock boost gauge).

My goal was to keep the AFR at 11.8+ and have my WOT timing no less than 18*.

However as soon as my car goes into 3rd gear I start to get KR and that is why I had to lower the 3rd gear RPM timing down to 17*. If not, I get KR no matter what. I actually still see blips of KR at WOT, however its normally like 0.2 at the most.

This is the reason why I feel the 2.7 just maybe is too much for my setup on pump gas?

SO do you guys think I should keep the car as-is or get a 2.8” pulley?

Ideally with the 2.8” pulley I will be able to run my constant 11.8 AFR and 18*+ WOT timing.

If anyone has a 2.8” pulley I would like to buy or trade with a 2.55 and 3.0 pulley I have left over.

You can look at my signature below for what mods I am running.

Similarly the MAF readings fell in sync with the injectors. I have no idea why this would happen. My KR was about maybe half a degree to 1 degree, which is nothing because I see worse than that under normal conditions at WOT so I guess I didn't do any damage but I can't figure why the MAF would report LESS air due to the nitrous....

Somebody please help me with this...I can upload my bin or scan upon request. Thanks a lot.]]> Wed, 12 May 2010 16:53:14 -0400 http://www.powrtuner.com/index.php?showtopic=7853 http://www.powrtuner.com/index.php?showtopic=7841 My question is will the series III MAP sensor work with the series II PCM, in the past I have always just used a series II MAP and be done with it but this time the customer wants to retain the smaller series III MAP.

anybody that has maybe rebuilt the motor, did you use a larger ring gap??? if so how large?]]> Thu, 04 Feb 2010 10:39:00 -0500 http://www.powrtuner.com/index.php?showtopic=7781 http://www.powrtuner.com/index.php?showtopic=7773
