I agree that dyno #s are just a tool (Need track MPH) but for fun I'm going to PUMP my numbers up.

If I had a T5 that is good for 30hp (See link)

FORD STROKERS DART 363 dyno..finally

Hey, Some of you know that I split my 347 last year, shortly after that I ordered a 363 DART from FORD STROKERS to replace it... WELL WORTH THE WAIT!! Some history... 347 dynoed (to the wheels) 426'ish HP and 416 foot pounds... great motor and put out more power than most people believed...

forums.corral.net

Dyno Jet Thats 12% see post #85.

396 + 30= 426hp (If T5)

426 x 1.12= 477hp (Mustang to dyno jet)

Looks good on paper LOL

Hoping to go to the track today. Number and trap speed I hope to post tonight. Car came in at 3540lb I'm going to guess low and say 11.5 @124mph. Guys this is a guess I didn't look at a Calculator. But Now I'm going to see what one says. 12.0 @ 119mph guess we will see how the mustang dyno did.

. Car came in at 3540lb I'm going to guess low and say 11.5 @124mph.

What the hell did you do to get the car that heavy? That is over 100 lbs heavier than my 08' Bullitt.

Unless your a very big guy, seems like your weight is high. Goodluck, hope it runs as strong as you are hoping for.

 

[Str8ballar]

I have done some street racing and I beat a guy that was running 11.8 @ 119mph so I had an idea. His car is very consistent. But I had changed wire today and pulled my intake off today. All I'm sure of is something wasn't right after it was going dead on me and it never does that and was going lean every now and then so maybe a vac leak bad plug. Not sure what I can tell you is she wasn't 100%. But this was my only chance for at least a month so I took it. Its an hour drive each way and the car drove nice at cruse speed. I had more gas in it today little over 3/4s so I would say car was 3560lb. Car went 12.602 @ 112.44mph with a 2.099 60ft 8.236 @ 89.35 1/8th. I just got my 2 step wired in and it was working but it would grab then fall on its face. Tried 3500 @ 32 deg timing and 3500 @ 28 deg and 4000 @ 32 deg blew the tires at 4000 RPMs. M/Ts S/Ss 315/35 r17. It may have held the 4000k launch if I would have did a little better burn out was in a different lane also. This is all my passes. The calculator I was using had me with a 1.8 60ft and a 12.0714 so with my 60ft They had me a 12.4. No matter what I have some tuning to do I got the logs and hope to try again next month. Maybe I can find this bug and get it out. Going to change plugs tomorrow and see what they tell me..

This to me is the best part. I ran a 12.99 @ 108 in my stock 302 with Gt40 cobra head and cam that was my best ever pass. But the 2 motors aren't even close one was tuned for years and the other is day one lol.

 

[Str8ballar]

So when I was coming off the Launch it was dropping down to 15deg of timing and about 3-4 points lean Through the run. Little tuning and I'm staying with my number. 11.5 @ 124mph (It hasn't done this but I say it will) Just like it sits.

First of all, congrats on taking it to the track. As was mentioned in your other thread, the intake is killing you. Hurting traction on the leave, and rolling over at the top of the tach. You dyno'd a little more than my 363 did n/a, but you ran 5 mph slower - my car isn't much lighter than yours (maybe 100 lbs) - but as others have said, yours is surprisingly heavy. I really don't think you'll get anywhere close to 124mph with that intake. You might pick up as much as 5 with tuning, but that's pushing it in my opinion - more likely you're going to cap out at 115 or so. FWIW, 124 mph is good for solid 10s.

Here's my dyno graph N/A (and I had a miss too - thus the hole in the graph; I didn't get it sorted until after I put the Whipple on - it was a Megasquirt problem):

Video on the dyno n/a:

Here's one of my N/A timeslips:

I'm car number 409. At the time, I was setup for the blower (powerglide, tight converter and I think I still had 3.73 gears in it), so n/a was pretty slow out of the hole, and a pretty boring ride all around, actually:

In my opinion, you'll never hit 120 mph with that intake, even if you take 300 lbs off the car. You also need some skinnies, and perhaps gear it appropriately (don't remember what gears you have). You have all these great parts, and you've topped it off with a lightly polished turd. Keep the GT40 in the garage for re-sale down the road, throw a decent (and appropriate intake) on it - a Box R, even an RPM II, along with the skinnies and you'll have a 10 second ride (after you things sussed out) that's completely streetable and fast. My $.02. But again, you're miles ahead of most - at least you've tried, tested and posted your results. Not many are man enough to do that. My hat's off to you. Hope my info helps.

If you take your weight and 112 mph, run it through a calc and you are making 387 WHP. You are where you are with that intake. It's common for a 363 with same/similar heads to make more like 450-500+ WHP and run 120-125 mph with a more appropriate intake. The flow numbers you were given might lead you to think the intake would supply the engine's full potential. Clearly it does not.

 

[AlexLTDLX]

There's much more to track performance than just dyno numbers and flow numbers - and I'm not referring to chassis/driveline stuff. There's shift recovery and acceleration through the curve too - many people don't take those things into account. That intake is clearly the bottle neck in an otherwise well done combo. FWIW, if you're only running 125mph and making 450 rwhp, unless you weigh over 4,000lbs, something's way off - at 3,450lbs, 450 rwhp will net you mid/low 10's at 129-130 mph. 500 rwhp is plenty to run 9's in a well setup, 3,400 lb car. But I've never seen a pump gas 363 make that kind of power n/a and deliver it on the track. My car's a compromise, and it goes high 9's/140+ mph with 557 rwhp on the dyno at 3,500+ lbs (depending how much ice is on board). I always laugh at the people who claim 600+ rwhp and can't crack mid 10's...

Usain Bolt running track breathing through a coffee straw. Swap that intake man, unlock that engine's potential.

Any plans to run a slick? Lots of time available in that 60'. Should be able to run mid-high 11's on a slick.

 

[Str8ballar]

You have to love the internet I tell you the car was running bad tell you what the data log even said and y'all say swap intake not get it tuned and bet she will do better I've already beat a guy running 11.8s without the 2 step its all a matter of fixing the tune. I have a Trickflow R sitting on the floor. Maybe next year I will put it on just to see how it does but I'm in no rush. Plan is get this bad boy tuned and back to the track make a good pass then put a little Nitrous to her and see how she does. When I'm done playing with the cobra intake I'll put the Trickflow on just for a short time to see how much better it does.

 

[Str8ballar]

Had no problems with traction problem was in the tune. I have a set of slicks on the shelf. As of now no plans to use them.

 

[tmoss]

How many mph do you expect to get from the right tune?

 

[Saleen414]

On the question on the weight. (I have this post on my build)

My 89 Saleen has a Dart Block 363 with 75 lbs of S/C and I/C sitting on top of it. It runs with 15 gallons of ice and water in the back. I still have power windows, all original glass except for rear hatch. All original sheet metal except for the 6" cowl hood that weights 18 lbs. and fiberglass rear hatch. The Plexiglass rear glass and hatch only saved 30 lbs from stock. I normally run 8 gallons of fuel in the tank (1/2 tank) the car has a 10 point cage in it and I weigh 240 lbs. Even with all of that, I would have to add 525 lbs to the car to get to your weight. 525 lbs is another complete small block and then some. Wow.

 

[Str8ballar]

This was the other day its the one the garbage truck uses I can go for free so it maybe wrong guess I could ask how

I have no idea why but it shows the cobra is 200lb heavier from the factory

often they check it

 

[tmoss]

I think those Ford numbers are dry - no fluids in gas tank, cooling, crank case, trans, PS ............
