dyno #'s

[94opalgt]

we bought a 94 vert a month ago and i just got back from the dyno shop, this is what it's got and what it made.

trick flow track heat h/c/i, 76mm c&l meter and pipe, 70mm tb, 24# inj, bbk unequal shorts, off road h, flowmaster cat back, short belt, pullies, autolite 3926's, msd wires. i think thats it.

tuned at Akron Horsepower

301.20rwhp
332.35rwtq

will try to get the graph up soon

 

[94v6GT]

auto or stick?

 

[Black95GTS]

Interesting that your stock cammed combo had only 2 less HP and 10 less RWTRQ then the combo with the TFS cam. So perhaps when myself, Grady, Paul, etc tell people not to swap in OTS cams and save up for a custom we just MAY be on to something.

Could we see the graphs of both that combo and yours next to each other? Grady would also like an excel file of the breakdown per RPM.

well, the heads in my sig were ported, these are not. my graph was lost at the dyno shop when there computer crashed, so i cant have them put both on one sheet. but i will send grady copy's of both and try to get them up here soon.

i am interested to see what this would have made if the heads were ported with a set of long tubes, but i will find that out next year when my car comes back out.

it is a stick car

 

[5spd GT]

Don't expect much with the longtubes as far as peak numbers...

I went with a 306, ported lower done nicely by tmoss and some longtubes...and gained 1.3mph. 13hp between all of that...and I don't attribute that to the longtubes if that gets you thinking

Those numbers equate to about 346hp/382lbft at the crank. I would have expected about 40hp more though so something's not right. Maybe the graph will reveal more but I wonder if valve float is to blame.

Most of the TFS h/c/i kits I've seen on these boards make 300rwhp give or take a few.

If he was at 350 crank hp would that not be about 350 x .85 = 298 which is taking into consideration a 15% stick trans drive train loss.

It seems pretty typical to me

I'm with David on the LT's and shortys being close when you talk peak hp in an application such as this one.

I give up!!! Why in the hell did I pay for someone to put a 347 in mine that only gets 313/346. I could have left the 302 in it and just bolted **** on for that.

Sorry, just a little upset....and don't know enough to change anything...

But it sounds good...hoohoohoo...and the damned thing won't even idle right and is running rich as hell...

I am about at wits end with this whole project if you can't tell. I thought that someone who builds drag machines could build a bad-@$$ed street machine, but obviously I was mistaken.

Sorry all, just whinin'

 

[Pokageek]

I seriously doubt that is a stock cam 302. No way. But if it is then put Grady's on their dyno and watch him get 335rwhp.

As to getting 400HP out of a 302? .. No one hear has done that with a "street" friendly combo..is this for drag racing? 50 more?? 302? Am I missing something?

[edit] As to the 347? Something in your tune is off. You will get that power out of your car, just be patient and take it to a good tuner.

 

[smitty_64]

I don't remember saying anything about getting 400 HP. All I want is the 350 that I should expect out of a 347. Not too much to ask.

And I know Pokageek, but I have been having people tinker with this car for a year now, and that's with two tuners. I don't get it. Grady said cam, and I am to the point of believing that that is the whole problem.

When I downshift, at 2 grand you can definitely feel the car starving for either air or fuel. Then it won't come down to 900 until the car comes to a complete stop. So it's racing when I step on the clutch, and continues to race when I am coming to a stop. Things don't seem right. It's like the car wants to run right, but other things are keeping it from doing it, if that makes any sense.

That aside, I don't believe that 350 rwhp is too much to ask from a 347 considering I could've bought a crate engine that had 500 at the crank.

 

[94opalgt]

smitty64- your car needs re-tuned. whoever is tuning it isn't doing it right thats for sure, and i would be mad too if i were you.

bullit95-why would you expect that much more with unported heads? this is all out of the box stuff here

pookageek- you can doubt it is a stock cam car all you want, my car made just what it said in my sig, with what it says in my sig. it's all in the tune, if you got a tuner that knows what he is doing. which i do. i wouldn't let anyone else tune my car but george, period.

as for 50 more out of a street, not race, 302? i'll let you know late this year or early next year when my car comes back out.

 

[TGgnatsum49]

i agree w/ pokageek here. There is something seriously wrong w/ your tune. w/ the right tune and combo it really isnt hard to get 300+rwhp out of 302 ci's, so i dont see why a 347 w/ a combo as stout as the one your rolling with couldnt make 350+ rwhp. Just some people that live in the same area where a reliable tuner can be found.

 

[blksn955.o]

you say you have the track heat h/c/i , is it just me or does the /c/ stand for cam? and IIRC the trick flow "combos" come with a TFS cam.

I think that is part of the confusion, that and your sig says ported and the ones on your car are not...just kinda confusing.

The stock cam has proven itself to make good power if properly setup...just look at the factory stock guys. If it is the stock cam how was it installed?

I just wanted to point out ... I'm pretty sure those factory stock guys do NOT
run the oem cam.

I think they have to run the oem cam lift specs but they can play around
with the duration and other stuff.

That factory stock stuff can be so misleading

[blksn955.o]

You are correct it is a play on the stock specs. However, IIRC that is a recent change as well within the last 2-3yrs.

I've seen similar combos using the TFS TW heads and Track Heat intake make ~335-340rwhp/335-340rwtq so that's why I thought the HP number was down and questioned whether there might be some valve float. I assumed a drivetrain loss of 13% (the T5 is pretty efficient) so I divided the rwhp/rwtq numbers by 0.87 to get flywheel numbers.
I think the exhaust might be holding him back a bit as well. Long tubes, X-pipe, and straight-through mufflers would have been a better-flowing combination.

the car that made 301 has a cam, the car in my sig had a stock cam. these are two different cars. and i know what the /c/ in h/c/i stands for.

and the stock cam was installed however they install it at ford.

 

[blksn955.o]

It just was not very clear with the sig and thread topic saying 2 diff. things.

either way they are great numbers. Speaks about the ability of the shop and combo.

Do you have any comparo of the two curves? It would be nice to see what one had more area under the curve.

 

[94opalgt]

i e-mailed grady graph's for both cars. maybe he can post them up here, if not, i'm going to have a friend do for me seeing as how i cant figure out how to.

Here are the two pulls in question

This is the Opal pull

This is the Yellow pull
