I just got my 347 dynoed today and was wondering how to get my HP numbers up. without replacing heads/cams/intake

HP 286.8
TQ 506.1
AIR/FUEL 13.4 AVERAGE

I was thinking was to lean it out a little and more advance timing might get me 300.......? Any suggestions?

Now you are using a e-303 cam
And your ported gt-40 with intake?
at what rpms were the numbers made?
shouldnt you be at like >350 horses?

I think you need to find another dyno. Or better yet, run it at the track and see what it does.

Yeah that sounds insanely high with the low amount of RWHP you have. I dynoed at 390rwhp with 375rwtq. Something sounds incorrect there. Was this on a mustang dyno? What fuel pump are you running? Hopefully not stock.

It's not a typo.. he's already got another thread about the dyno numbers.

Please, post up a picture of your dyno graph so we can see why you got 500 ft/lbs.

at this point, i think that adding HCI will gain more HP. I would think that adding some simple edelbrocks, trickflow or a gt40 aluminum head will add more HP. a More aggressive cam will help too.

but heres a question...... if you add parts to make more HP, will you lose tq? will you be OK with losing hp if so?

As suspected, you aren't making 500ft/lbs. First off, remove that POS "super" chip. Then set your timing to 14-16* and see what happens. He should have stayed on it til 5800-6000.

Looks like something wrong with the dyno. I believe the curves should cross at 5250 or so and those aren't even close to looking right for the numbers on there -- the first run is probably closer to accurate as far as numbers go.

Adam, thats because the hp and tq numbers aren't set to the same scale. (both numbers on the same side)

328 tq cant be right...last year my old 302 made 267.0hp and 315 tq before the stroker. And this was a tune shop. There has to be something wrong with the dyno there(carlisle) . Both dynos were ineritia(cant spell it) dynos to.

Well, just look at that graph... There is no way it could have REALLY spiked like that. You probably made what it says on the other run. If not, go to a different dyno.

I agree....Ill have to get to another dyno. After looking at the graph the HP numbers dont make it to what the graph says anyway. and the same for the tq except higher.

The torque line of the first graph does not match the 500lb-ft indicated in the print - the dyno or operator tripped up.
