Took the L to the track for the first time tonight. I've run the stang and the bike before, but hadn't had a chance to run the truck.

Mods are (pervious owner installed): Pro-M 80 mm MAF, JBA shortys and Flowmasters. I raced will full street weight (hitch, spare, and tailgate) on BFG Comp T/A ZR's at around 32 psi. My goal was to see what it ran in full street trim before my chip and pulley come in shortly.

Best time was:
2.05 60'
13.26 1/4
103.76 mph

I need to lower the tire pressure a little to really hook. My 5 runs were 13.30, 13.32, 14.10, 13.29, 13.26 all at 103.xx mph. The 14 was right after they sprayed a fresh layer of traction compound. Traction my ***. I slid straight sideways when I rolled into the throttle. My friend I was running against did the same thing. But we didn't have a choice since we were already in the lane when the decided to hold the start and reapply.

All in all I am impressed with the times. I assume with my PSP chip, 4 lb pulley, and denso's that are on the way I should be safely in the 12's. I ran against another white '99 on my last run who had 4 lber, chip, single blade TB, and boost bypass and he only ran a 13.1 at 106. I hope I pick up more than that.

 

First of all conrats on the times, you have a strong running truck.

I'm curious about the MAF....I had a pro-m 80 that I bought from Swanson a couple of years ago and the damn thing made my truck go nuts. It seems the meter was actually meant for a mustang application according to the serial numbers, and it made the truck thirsty for octane, I had to poor in 100 octane all the time to keep it from rattling. But I got similar numbers at the drag strip to yours.

Does your truck need a lot of octane or is it normal....like I said just curious.

'99 White Lite, those are great times for your mods. WIith your new mods you will most definately be deep into the 12s. Good luck!

 

Congrats on the times!

Congrats.

I'm jealous.

 

Bad as L,

Previous owner did the mod and didn't still have the factory parts or I would have probably switched back. And you are right, it is calibrated for a mustang that has been converted to 24 lb injectors. That's not really a big deal, though. Every MAF sensor has a transfer function from volts to air mass flow. As long as the MAF you put in has a similar transfer function to what came out, it should be alright. The intended application doesn't matter. I THINK that the Pro-M transfer function shows a little bit less air than the factory sensor so that the truck leans out a little bit, and picks up a little power (plus its less restrictive).

I haven't had any drivability issues or pinging that I know of on 93 octane. But I also have never driven an L that still had the stock MAF so I probably wouldn't know what the difference was. Driving home last night I thought I might have heard a little pinging, but the flowmasters are so damn loud its hard to hear if there was any or not. Personally, I don't like to use aftermarket sensors and thought about the 90 mm conversion when I got the pulley and chip. I decided against it for now, but might buy one in the future. I told the tuner that this is the MAF I had, so the chip should correct the readings back to actual airflow anyway. I just hope the combination of the chip and MAF don't mass things up.

 

That may be where my octane problem came from....I was running a chip with the meter. It was fun to drive tho.
