94 cobra rwhp numbers

I don't know if this is what you're looking for exactly... but, the rule of thumb is generally about a 15% drivetrain loss through a manual tranny and 20% through an automatic.

So if you want to guess that it's 270 hp at the crank, plus 15 crank hp for the CAI & Exhaust, then you could expect the following at the rubbers:

• Manual tranny: (270 hp + 15 hp) * 0.85 rwhp/hp = 242 rwhp
• Automatic tranny: (270 hp + 15 hp) * 0.80 rwhp/hp = 228 rwhp

Maybe somebody can verify these numbers...

Hope that helps. :santa_cool:

 

a 94 cobra puts down 220-230 rwhp.with a cai and full exhaust i think somewhere between 235-245 :dunno: they were underrated for sure. only one way to find out for sure strap that baby in a dyno

 

Stock 94 Cobra over here.
I should dyno it before I start modding it.

 

yup, I did the same with my 99 and im going to have dyno sheets for the pre blower number ( that is with my mods now ) and the final numbers after the blower. I was at 270 and 280 STOCK.

 

if it wasnt for the irs it should be a little higher than that.

 

well with the drive train loss its right at ( or was back when it was stock ) the 320hp and 317tq factory rating. Just about 3hp under to be EXACT, im interested to see exactly where I'm at now, I'm guessing around 310hp and 300-315 or so on the tq. Wont know until I get back to the dyno right before my blower is installed.

 

does the irs take a lot more power than a solid axle or just a couple more hp???

 

im not sure, I have never heard mention about it :dunno:

 

4ci isnt gonna help. the reason people bore their engines is because they have to. if u want power either get a h/c/i (heads, cam , and intake) or get a stroker kit 331ci+ . the HCI or supercharger will help u the best.

 

not really, if any hp is gained its minimal. Unless you have a 306 with some kind of high comp pistons that give more hp, other than that comparing the same motor with one having 4 cubes more is not going to give any thing too you.

 

5.014L versus 4.949L is a difference of 0.065L (65mL).

Assuming you consider a stock 1995 302 @ 240hp = 48hp/L.

Just to give you an idea, a proportional gain would be about 3hp. This is not an accurate way to predict hp, but would give you an IDEA.

thats only with exhaust and timing bumped to 14* degrees

 

those are nice #s for a pretty much stock cobra

 

If your looking to make more power in a pushrod I would defiantly stoke over boring it. I had a stroked a4 347 with an HCI setup I made 310 to the ground with all supporting mods and a tune. I have a buddy with a 306 hci setup all supporting mods and a tune and he made 278. I found increase the stroke on 5.0's really wake them up compaired to a 306 bore. There was a right up awhile back wit MM&FF about this and the stroker kit did produce better numbers. 331 kits seem to be gaining alot of popularity over the 347. But I did mine about 6 years ago. Alot has changed since then. Good luck

 

I made 253hp/294 tq with BBK equal length shorties, BBK o/r X pipe, Mac Pro dumps, ebay CAI, UDPs and 15° timing.

I also had an air fuel ratio that was pegged lean at around 15.5:1

I added an adjustable fuel pressure regulator and messed with a couple values with my old Tweecer, and I hit 276rwhp

 

I heard 94's came with a conserative tune around 240ish HP, and if you tune it with a more aggresive tune, you can get around 270ish?? :dunno:
