How much Hp should I have?

Black87Fox · May 18, 2011

Hey guys, I'm new to the forum and I was wondering how much HP an explorer intake, E-303 cam, edelbrock Performer RPM heads with 1.6 roller rockers, under drive pulleys, amd BBK shorty headers should make? All input is appreciated, Thanks in advance.

without a tune, 250rwhp. Tuned probably 290rwhp.

must be some kind of magic tune to pull 40 hp out of it. I'd guess between 250-280 at the tires. Chassis dyno's are not all created equal

You never know with fuel pressure, timing. It could be running super rich...

I picked up 27rwhp with a tune, and the car was "tuned" two years before.

I read a post a day or so ago that a member was getting 208/270 with the same cam and intake, but I believe he was running P heads and 1.7 rollers. The rest was pretty much identical.

The board concensus was that the numbers were about right.
He was worried they were low.

I just found this in the 'talk' forum:
http://www.stangnet.com/mustang-forums/838230-got-ol-girl-dynod-last-weekend.html

He's got the same stuff as well, and pulled 280/307 while getting it tuned.

So, I figure the 208/270 really is low. ??? I have never had a 5.0 dyno'd, so I just went with the flow.
I believe that post was in the SN95 forum.

I wud say 275 rwhp max. just my opinin.

bgoins · May 18, 2011

Need more details. Throttle body, maf, injectors, trans, midpipe, exhaust, fuel pump? With the right supporting mods u should be looking at around 300rwhp through a manual trans

Black87Fox · May 19, 2011

BBK 65 mm throttle body, 90mm MAF I believe calibrated for 42 pound injectors, green top injectors, t-5 WC tranny, no a/c, flowmaster american thunder back from the headers, not sure of the h pipe and a holly 190 lph fuel pump and a vortech v1 s trim at 10 psi.

Im with you!

Kdubslugga · May 19, 2011

Whoa whoa whoa whoa............It has a blower on it?

Black87Fox · May 19, 2011

Yea, I was just wondering how much hp it would make with/without the Vortech. frankly I'm a bit disappointed with 275 considering how much money and time it cost just to get there, I figured I'd be at least 300. But thanks for all the input guys

bgoins · May 19, 2011

U should hit 300rwhp NA with what u got

Dont get stuck on chassis dyno numbers. If you went to three different dynos on the same day there is a good chance you would get 3 different results. Its more of a safe tool to figure out what the car is or isnt doing well

f8tlfiveo · May 19, 2011

Yeah I agree they vary but he should be in the 350+ range with a blower..I'm making 275hp at the wheels with a gt40p setup with a couple bolt ons.. Somthing isn't right..

Black87Fox · May 19, 2011

Oh, yea I know I'd be in the 300's with the blower, I'm just disappointed that I put a lot of time money and work into the motor just to get 50 extra hp from stock without it. I'd be content with 400-450 to the wheels

bgoins · May 19, 2011

Well, do u have a track nearby or dyno u could take it to?

f8tlfiveo · May 19, 2011

Your really about 75-100 more hp than stock.. 225hp *10%or 15% drivetrain loss puts you at 200 hp or less at the wheels.. So that's not to bad.. I thought you had 275 with the blower..that would have been pretty bad.

You really should be close to the 300rwhp without the blower.

How much Hp should I have?
