Lex sent you a pm to give me a call.

 

Thanks for the replys guys. I am planning on putting together quit a serious motor. Hopefully featuring a new full-race.com manifold design for the na guys (That is once my race car is done hopefully sometime this winter) . Im not sure either to get ride of, or keep the distributor. I know the individual coil packs will give a stronger spark than the distributor setup, and lower chances of arching. Any more feed back welcome.-pdang

 

What are the details on the new intake manifold? I may be interested..

Not w/ the AEM ECU.. The sequential ignition is converted to wasted spark, which gives the coils less charging time, thereby decreasing their output. The distributor should be better in this case; the only drawback being that it's IN THE WAY.

 

Sorry man its not an intake mani, its a new design turbo exhaust.
Thanks for the info on the distributor change over.-pdang

 

I'm running the AEM with LS1 coils on an sp63 with a 4" inlet. The LS1 coils don't suffer from the problems of the TT coils packs because each coil has its own igniter. Consequently, the short dwell time isn't a problem in wasted spark. *Plus*, I only use the distributor for crank/cam position. In other words, the distribtor is *not* in the way.

The coils should be good to at *least* the mid 20s in boost. Dave H is running this setup, too, and he's having problems with misfire at high boost. However, he doesn't have the coils ground well, and he's in the process of reworking the grounds. Other TT owners have put big numbers (600+) to the wheels using the LS1 coils; so I'm not at all concerned about the short dwell time.

P.S. I'm currently tuned to 13lbs of boost, and the car pulls *very* hard. I still have 2 rows in the fuel map to tune to get the car up to ~17psi on pump gas. Once that's complete, I'll start tuning with methanol/water injection on pump gas (93 octane). Then we'll see what the coils do at high boost.

 

Damn, thats good to hear. you can get rid of the distributor and use a mk3 cam sensor (part number 19300-42010) Any shots of your setup?-pdang

 

Don't know why I was thinking intake manifold...

 

You're right about the mkiii cam sensor, but I just kept the GE distributor. In fact, I don't even cover the thing.

I started a thread about the initial install. Just search for my posts. I'll post pics once the methanol injection is complete. A couple of CL members have seen it in the Dallas area. Unfortunately, I didn't have it finished at the last CL meet in Dallas.

I went for the total sleeper look. The FMIC (24"x12"x2.75") is *very* difficult to see, and I had the OEM exhaust tips removed and installed on double offset Magnaflows when setting up the exhaust.

It so fooled a modified Porsche following track night in Ennis, that he flashed his hazards when he went by me (my car was completely untuned). When I jammed it into third gear and got on the boost, he could hear the sp63 spool and knew he had his hands full. He barely got around me again but rolled down his window to pull off. When he saw what was under the hood, he was very thankful my car wasn't tuned. At the time I was only running 17lbs of boost on pump gas. He was about 800lbs lighter at 20psi on race gas.

My car actually runs better now at 13psi tuned than it did at 17lbs untuned; it just doesn't pull as hard to red line once full boost is reached

Damn nice....Your in Dallas huh, next time I'm up thier I'll have to hit you up. Im always heading to norwoods to get stuff done on my race car.-pdang

 

AFAIK... The new sc300 aem unit will just be a supra unit with a few different options... Probaly not any different than the supra unit I have working my distributor

 

My question here, is with the fuel injectors.. Why bother with all kinds of resistor packs, and alternative injectors, when there are injector companies out there who can take your used, stock injectors, and modify them for over 600cc capacity? Then you could simply modify the fuel rail to take fuel from both ends of the line, and return from the center, not having to do anything with any other aftermarket stuff?

Or has someone tried this, and it doesn't work?
