Ok heres my problem.... Car runs good, but when I need to pass someone, or show off a little my car studders when it reaches about 4,500 RPM. It did it bad for about 2 days, but it kinda cleared up. It was so bad at one point, it wouldn't go over 4,000 RPM. I don't know it just feels like...

has anyone uses the Moroso cold air intake? I was just wondering if it is any good. I looked in to the K&N but I don't like the design, its just a filter with hardware, and its expensive. The Moroso is only $113 and its the whole kit. So if anyone has used it and likes it let me know, or let...

Ok heres my exhaust combo. BBK Long tube headers, BBK X pipe with high flow cats, and 2 chamber flow masters. I just had the X pipe installed, and I am disappointed with the sound. It was louder with the same exhaust, but the stock H pipe. I don't understand. Why do you think its like that?

Ok heres the deal I have a 89 coupe. It runs good, except it surges at idle sometimes (so bad it stalls). I don't know what that is caused by either. It sounds like a vaccum leak, but I can't find it if there is one. But anyway today when I got the emissions done it failed for CO and HC! Im...

I have a stock 5.0, well B303 cam, but thats it as far as the engine goes. And I am wanting to go supercharger, but I don't want to mess anything up. I was wondering what is the most boost you should go with a stock motor. And I can't decide which system to go with. So if any of you have any...

ok i don't know if this is true or not, but i was told by the local ford performance place, that if you only put 4 1/2 quarts of oil instead of 5 you will pick up about 10 horsepower to the wheels. but i don't really know if it is true or not, but if any of you know about this, let me know. thanks

Ok, I am debating on what kind of power adder I want to go with... I am really kinda clueless on what I want to do. But the main question I have is what is the best supercharger to go with?:shrug: I have a stock motor except LT headers and B303 cam. Do the supercharger kits really come with...

ok i am reposting this question, because i didn't get any feedback. OK.... when i first start my car in the morning before work, the transmission slips. It works at first, but the first time i stop and try to drive off it the enging just revs. then after 5 seconds of nothing it engages and it...

ok i have a few problems, so here they are.... I installed a set of BBK LTs and i haven't put in the O2s yet, so thats probably my problem with the engine not wanting to idle when its cold. so thats getting done today. and i have another problem, my tranny is slipping when it is cold too?? i...

a friend of mine has a NOS fuel pump for 5.0 mustangs. he wants $100 bucks for it. But is it really that important to run that pump with nitrous? whats so special about it? and if i decide to go with it is there anything special i need to know about before installing it? what is necessary to...

Whats up guys. I was wondering if putting nitrous on my mustang would be a good or bad thing. I know that nitrous has a bad rep, but i know it is safe if it is done right. My motor is stock except the B303 cam, and i was wondering what shot i should use, and where i should set my timing to...

Smog Pump Delete, Worth It? I was wondering if getting rid of your smog pump is really worth it? Do you really pick up that much power? And will you pass emissions if you don't have it? Is there a kit out there that you can buy, or do you just have to re-route the belt? And what size belt...

Ok i finally got the headers in after a long day! I had trouble eariler today with the shift linkage on the transmission, so i posted a thread, and called some of the local performance shops and summit. Summit and the performance shops said that " no one makes long tubes to fit an AOD...

ok, I got my bbk long tube headers i jacked the motor up, and removed everything needed to complete installation. and i am still having tons of trouble with header clearance. They just won't bolt in. drivers side collector is hitting tranny, and passanger side K-member is in the way. The...

there are a lot of cold air intakes out there.... i was wondering which one you guys think are the best. i heard that the plastic intakes are better because of heat issues. so which one is the best bang for the buck? id like to know how the numbers looked on the dyno too.

Header Help hey guys.... i am in the process of installing a set of bbk lt headers, and i am having a hell of a time doing it! I have heard that you have to grind or remove the k-member to complete the installation, and then i have heard all you need to do is loosen the motor mounts and jack...
