My new drag toy. 93 lx coupe carbed LS1/th400. (pics) by JRracing

9 minute(s) of a 190 minute read

I got it down off the jack stands today. I took it for a little drive and it is running like ****. I put a old set of 7's in it that were pretty gassed up. It is popping and breaking up pretty bad if I get above 3500 rpm's. I think it is really rich or really lean. And my lc-1 is acting stupid. It works fine when I reset it then about 2 minutes later it freezes up. I reset it twice and it has done this. I think it needs a new sensor. This one is 4 years old and has seen a lot or leaded race gas.

A few pics from the other day.

I've been slacking on this thread and posting pics.

Update..

I ran a PB at the Holley LS Fest. After the rain went away on Friday and they got the track ready, we hit it for a few test runs on the 275 radials. The track was great. It was cutting low 1.4's and high 1.3's.
After several 10.0x runs I turned the two step up to 4K and let it eat. It cut a 1.36 60' on it's way to a 9.98@134.

Finally! A 9 sec run on motor. I am happy with that and ready to put some spray to it. I am starting with a 100 shot to get it dialed in and get my license runs done.

I hope to be testing it next week. My goal is to have it ready to spray at the shootout..

Here are a few pics from LS Fest. They are scanned so they don't look the greatest.

A few more from 1320.

Update.

The testing of the nitrous didn't go well. Or not at all I should say.

I have had nothing but problems with my car after the LS fest. The ignition is breaking up at 7K rpm's. I thought the problem was gone at the LS fest with it running a new pb and all. When we get back home the car starts breaking up again like last year.
I never got a chance to spray it before the shootout.

So at the shootout it was still doing it. And really running like ****. On Saturday night I finally got the idea to run a power wire from the batterystraight to the box and put a switch in between. What do yeah know it fixed it. It went 10.44 spinning like crazy. The next day I got put out in the 2nd round of the index racing. I didn't care cause I found my problem haha.

This was only after buying a new box from SCPC on site (thanks guys) and changing the coils, plug wires and plugs. I felt like a dumb ***.

It was the power going to the box the whole time. It was not getting proper voltage at 7000 rpm's and mis firing.
MSD 6010 users please take note!

I chased this problem for over a year and it was as simple as putting a new power wire to the box! Geeez. Makes me wonder why I do this ****... LOL.


So I finally got it figured out and I'm ready to spray..
First I run it on motor a few runs to make sure things are cool. And it was. Went 10.04 first pass then a 10.04 2nd pass. Then I put a set of br8efs plugs in it. It's jetted for about a 100 shot or so. I got the right range of fuel jet in it to start with. I set the fuel psi at 5.5 psi flowing through the noid and the jet being used. I pull 6 deg of timing to be safe, from 36.
I get out there and decide to activate it in second gear by way of wot switch. I left at about 3/4 throttle and then after I hit 2nd gear I put it to the floor. It came on and the tranny went ziiiinnnggg.
I got over against the wall in case it was leaking. I coasted it out for a sec and then I put it in 3rd at it finally picked up. I go drive it around the pits and it does not want to shift at all.
I get home and pull the the big lug(th400) and my buddy took it apart and said the sprag rolled the bearings. Other than that everything looked perfect. The clutches looked great but a few steel disc were glazed a little.
I ordered up the parts and it is back together now.

I started putting it in tonight. It should be finished and off the lift tomorrow night.

I hope we get a few more shots in around here before the cold sets in for the season. I want to get a few hits in the car to see how things feel like the converter and tires.

I'll be pissed if I don't get another shot after that ****!!

12-7 Update.

I got one more hit in after fixing the trans. We went to Edge water in OH on a Friday night in Nov. The dew set in on the track and it was a pedal fest. I was getting side ways at 1000'. So I parked it for the season.


I am already under way with my 2011 tear down and improvements...
The car is a a buddy's place getting Wolfe mini tubs and off set arms. Cutting the 8.8 down and putting Afco doubles and strange pro drag brakes on it. And I picked up a set of M/T ET's in 15x10 and 15x3.5. Right now it has a BFG DR 315 on it but I'm going to switch the tire after I run on it for a few times to see how it does.

I am also moving the motor back as far as it will go. It sits kinda far forward now. 56% frt/ 44% Rr. And putting a tube rear bumper with a chute mount on it. In case I need it lol. And put a automatic shifter in the car.

My goal is to make the car very consistent and safe. I plan on running more index style classes this year alone with bracket racing. And playing with the spray from time to time.


I am finally done with the license bull ****. I have a number and my dues are paid. And my car is certed to 8.50 ET. I'm ready to sit back and enjoy this next season!!

You boys better look out in true street next year at the shootout..

Once I get the car back from the chassis guy I am pulling the motor and taking it to Mike Duke Racing here in Indy. It is getting new rings and bearings. I have two seasons on the motor now and we set the rings up pretty loose when my buddy and I built it. It blows oil out like crazy. And they were cheap *** Hastings moly rings that came with the pistons. I picked them up used but never been in a motor and someone took the diamond rings out of the kit somewhere along the line..

It should be a solid 10.0 car on motor.

The new wheels and tires to replace the drag lites. It is a 325 BFG DR and ET fronts. I will have to put sportsmans on the front for TS racing. I was going to pull the BFG off there and put a 295/55 MT on it but I think I will sit tight and try the BFG's at first to see how they do for myself.. Then pull them off if I do not like them. But I want the car fitted with the widest tire it will ever have on it. Make sense?
