260 CRANK hp. Not rear wheel. Listen, we have all been around the block, and we would know if you could achieve 300 RWHP w/out heads and cams.

With FULL bolt ons, (minus heads and T/B ONLY) I maxed out at 288 rwhp. That is with one of the best tuners on the east coast tuning my car. There is no WAY you are at 300 rwhp w/out heads/cams. There just isnt enough bolt ons that can get you that high. Either your numbers are crank HP/TQ or something was off.... Trust us. We are not jealous I promise.



but back on topic, get a supercharger for sure. Depending on the pulley size, you cna make whatever numbers you feel comfortable with. I make 408 right now and If just put on the next step up pulley, I will make 450+

You wouldn't make 370 with heads and cams. TO THE WHEELS NOT FLYWHEEL.

find a little vortec, throw a 9psi pully on it. then you'll have 370-400 to THE WHEELS NOT FLYWHEEL.

Your welcome.

i think its 275hp all motor and 25shot of spray..lol = 300rwhp

i had a novi 2000 on my 02 gt and it made 400rwhp & 400rwtq on 10 psi with water/meth injection. the water/meth was the key to making the numbers. I only made 365 rwhp & 375 rwtq without. hope this helps.

Damn dude 300hp on a dyno ?? Thats a factory freak or you have more then you know. Anywho I never seen a 2v or 4v dyno that with out a blower or H/C work but if thats what your mustang is putting down then sweet jesus grats ! I say throw a Procharger on that bad boy and go rape some bowtie boys.

[04 lazer red gt]

i would deffinatly go with the supercharger. jus get it tuned and dynoed right and you will be laying down 400-425rwhp easy. max boost i would say for stock bottom end would be 8 psi. good luck deciding tho

[Mosttasteless]

OP just curious if you know what Compression your engine is at ?? Did not proof read whole thread.

4Vs can put that down all day long with minor bolt ons.

I believe you will be happy with that choice. Assuming you have 4.10s, a lot of guys say you can put on 28" slicks to water down the gear a bit.

N/A with 4.10's you should not be redlining unless you're staying in it way too long. I think earlier you said that it runs 103mph in the 1/4, which is no where close to redline, unless your tach is way off. I just put a Vortech on my car last month and I have 4.10's, and will still be fine in the 1/4 mile. On a 26.1" tire you should be able to hit around 112mph at redline.

Dude get what will make you feel better. Quick HP and room to grow = Supercharger
NA power which is badass in my book -- Heads, cam, manifold, injectors, pump, great tune, & maybe some added compression and you can make so real HP to the wheels on that motor but will cost you prob double what you can get a used charger for.

** Off topic ** I put down 260 / 300 to wheels & I have full bolt ons. Just added a stewart water pump which prob give me 5-6 to wheels so thats 260. Also mild cams suposidly and mild port & the tuner said that my motor pulled strong for what was done so If you are at a legit 300 to the wheels I really wonder where that 40 is comming from B/C I want that! ha. You say car stock 260 but in reality it is like 200 to the wheels & maybe 220 if your lucky so IDK bro. +++

Welcome!

Yeah you should post that Dyno sheet. Would like to see the power curv. What type dyno? My guy had the DynaPack dynos.
