No HP Gain

oldbaldguy · Jul 18, 2007

I have a question. I own a 00GT with a CIA and cat-back. I installed a 75mm TB and Plenum. I haven't noticed any gain. So, do I go with a chip or a hand held tuner. Thanks.

Is this on a dyno, at the track or by the seat of your pant?

By the seat of the pants.

CAI wont do anything. catback will give it a better sound and maybe 5-10 hp. a 75mm TB is overkill for a stock engine but may give some hp. the plenum may give 5-10 hp.

i had full bolt ons and it didnt do much at all. if you have the money to spend just save it to get a s/c.

gears would be a better purchase if you are looking to get more performance

First I do not think there will be a large enough increase to fell. Second for most street driven cars that are not redlined all the time you will notice an increase in torque more than an increase in HP. Note not all mods will increase both.

Plenum and TB together would net 10hp at the most(probably less) on a N/A car.
I changed just the plenum and picked up 4 or 5hp.

Add a centri and you will have a noticeable combo with the new TB and plenum

Thanks for the input. I guess I need to redline this baby more often!. How about a chip or handheld tuner?. I don't drive it everyday so fuel expense isn't a big deal.

4.10 gears then a tuner

What do you want out of the car? Do you want it to be a 300RWHP+ car or what? If so then skip all the worthless bolt ons and just buy a supercharger. If you don't care about that as much then get gears, a tuner, waste your money on bolt ons and get it dyno tuned as well.

I was thinking about doing something similar. I would like to reach 300RWHP n/a because i drive this car daily and want to keep it very reliable. (It's also new to me, which makes me a little timid about SC) I also have a very limited budget ($2000~), are you saying this is an unreasonable goal?

Would you be doing your own labor? 300RWHP on a non Cobra Mustang is a spendy venture. It requires cams, full exhuast (including headers which are the biggest PITA on planet earth to install on our cars) and every other bolt on.

You're looking at $550 for cams, $200 for catback, $200 for midpipe, $500 for headers. The labor/time required to buy and install a supercharger would be MUCH easier than all the time spent doing the above mentioned stuff.

Since you don't seem to know a WHOLE bunch about the cars, I'll elaborate slightly.

Cams are a female dog to do just because our engine bays are crammed to the brim with wires and hoses and crap. There are plenty of how to articles if you search for cam swap or something like that here (the writeup in my sig has links to other writeups that could help you, especially HotMustangs HOW TO for VT Stage 1 cams). It's a 5+ hour job.

Long Tube headers (don't waste time with shorties, and if you live in Cali good luck reaching 300RWHP legally) require you to drop the K-member to install. It is possible to do without dropping the k-member but I'd be wiling to bet you'd be on Americas Most Wanted before you finished the install 3 months later, and if you have big hands don't even try. Dropping the K member entails removing the entire front of your car basically, its a 10+ hour job probably.

Labor on the above mentioned parts would be $2000 alone if you brought it to a shop.

good luck!!

you will spend way more to get 300 N/A power than it would cost you to supercharge it!!

Unfortunately they are correct With the mods in my sig along with the dyno tune I could have bought a supercharger....................live and learn. If ya want to stay all motor stick with it but be prepared to pay out the nose for gains that a supercharger (centri or roots) would blow out of the water

oldbaldguy · Jul 18, 2007

Thanks again. Guess I need to find a cobra.

Kilgore Trout · Jul 18, 2007

4.10 gears, shifter, and a custom tune and you will have a badass Mustang for under $2000 if you DIY

no, you just need a blower or some spray if you really wanna play!

BigDave06 · Jul 18, 2007

Thanks for the input, although its rather discouraging

I wouldnt be paying for any labor btw. I have installed a short throw, 3.90s, and cat back magnaflow exhaust system w/ catted x. I planned on doing under drive pulleys, 70mm TB/Plenum, K&N Intake, VT Stage 1 Cams, and a dyno/handheld tune (need to research more on this before deciding). But i really wanted 300! I guess if i came up short i could always buy some altezzas and a few decals.. Everyone knows those add tons of power

Add exhaust, and yeah

May not be the fastest, but it would still be a fun ride.
