I have a built B18A1 LS motor it is a Dart solid deck block eagle crankshaft eagle H-beam rods JE/SRP nitrous pistons at a compression ratio of 9;2-1 ARP head studs cometic head gasket the LS head has been ported and polished ferrea 1mm oversized intake and exhaust valves crower 404 cams crower double valve springs and the performance list goes on!!! my problem is that i am spraying a 175hp shot and when i use the nitrous with a 175hp fuel and nitrous jetting the car falles off in the high rpm of 3rd gear like a really rich condition i have changed the fuel jetting down to like a 150hp fuel jet or even a 125hp fuel jetting and the problem is not as bad but i then i run into the problem of running lean what do i need to do i have a microtech elx10 engine managment and a msd ignition system anyone have a fix for this!!! i also have tried different heat rang spark plugs and it makes no difference the plugs are ngk racing plugs!!!

 

Didn't you already post this?

 

Yes last night but problems and lost everthing you were the one who posted me back last night wright!!! I think you ask me if i have ever dynoed the car !!!!

 

Get rid of your MSD ignition for one. Then 2, your running lean on nos? Are you running a wet shot or a dry shot? If wet, maybe look at getting the car tuned using bigger injectors. Hit a dyno, you will get it tuned to accept the nos shot. You aren't just suppose to nos it without a tune. It's hard on the engine.

 

Oh, and I'm posting again to make a point.

Grammar is your friend. Learn to type using proper sentence formation. Makes it alot easier to read and reply. Also, make your point clear. I almost didn't wanna read it all cause it was just a bunch of words in a row.

 

Sorry!! I have a nitrous express wet system directport and i do have bigger injectors they are rc 310cc the car was tuned for all motor then on nitrous but only like a 100hp of nitrous
