My CHI2K6 Dyno run

[rumptis]

Basically stock 89 Turbo. not sure how much boost I'm running I hope to know soon but here is my dyno run and dyno sheet.

*Sorry for crappy image don't have a scanner handy*

Only thing done to this car has been replacement of the HG, rods and main bearings and all seals. I removed the first 2 Cats and put on a diff air filter and a MBC.

1st Run 238 HP 279 Torque
2nd Run 237 HP 290 Torque

"My Dyno Run"

 

[rumptis]

everybody must be jealous of the big numbers...WOOT!

LOL. Jason, don't forget to mention that it's actually about 15% more than what that reads.

You had 273rwhp and 320ft.lbs.....RAW POWAH RIGHT THERE!!!!!111

I had 307rwhp and somewhere around 360ft.lbs.....

*EDIT*, I keep forgetting that my tranny robs horsepower, so to the crank, I'm probably about like 800hp to the crank.

Was there a wideband available?

I made less than that with my 7M on a dynojet with more mods. I also was so rich it was off the scale, so that might have had something to do with it.

No wideband.

Running "reallly reallllly" rich as you speak and going off the scale, yeah, that might have had something to do with your uhh...horsepower numbers.

Running really rich...did you by chance have a boost leak? :love:

I kinda eliminated the boost leak possibility with hardpipes, silicone couplers and t-clamps. Here are the sheets if you want to look for comparison:

It was a rebuilt 7MGTE .030 over. N/A cams, stock turbo shimmed at 10PSI, HKS downpipe, 3" Catback, Flowmaster 40 Series Muffler.

Feel free to watch the videos as well but they're hosted on my cable connection so kinda slow.

It was later revealed that I had a clogged cat, so that was removed. Both my 7M and 1J are going to the dyno this weekend so I'll see if it's improved.

I'm running stock exhaust as well...just removed the first 2 cats. I might be up close to a bar, I know I'm really close to fuel cut off.

Wish they would have run the wideband I'm not sure why they did not, I'm sure they have one.

I really find it hard to believe it’s off that much if at all, I know people say that but my car doesn't feel as strong as those numbers with 15% more and I have had a car with that much power before.

I wasn't really expecting almost 240 at the wheels, thought I might be close but not that close, I'm really happy with it. I will be putting a boost gauge on sometime this week so I will know what kinds of boost I'm running which may clear things up.

Unless I hear a general consensuses on Mustang Dyno’s I'm sticking to the numbers I have on paper which seem more in line to the seat of the pants feel.

Your HP and Torque don't intersect like they are suppose to at 5200 or whatever it is, deff something wrong there.

Keep us posted I will be interested in seeing what happens.

 

[suprahero]

I had never heard that about the hp and torque intersecting, but mine does it at exactly 5200 rpm.........lol

Not bad numbers for almost stock..................lol


This dyno was done without a boost controller. It spools up alot faster now, since I've installed the apexi avc-r.................lol

I think that was brought up when I first posted the results. Can't remember what the reason was, but we figured it out later.

 

[hottscennessey]

Even with a boost leak, and fuel problems my HP and TQ still intersected at 5.2k RPM as well... weird!

N/A cams

 

[jdub]

Good numbers Jay...you too Hot :icon_bigg

 

[suprahero]

Hott is right on my heels. I think I'm going to go up my boost right now just so he can't catch me..................:biglaugh:

Thanks Jdub.......................lol

Edit: I must have given you rep recently, cause I can't give any to you now..............lol

 

[hottscennessey]

LOL SH, We'll have to meet up and have a show down

Edit: haha likewise SH!

 

[suprahero]

No, I'm much braver when typing over the internet..............:biglaugh:


I'd love to meet a bunch of you guys, but it seems I live a good ways from any of the meets. I think I'm going to talk my wife into going to the Chicago meet next year and just stay up there a few days............lol

I'm not sure why they do but I know they are suppose to...maybe one of the brains on SM can chim in and explain this to us.

Well seat of the pants feel means nothing. :icon_conf I've ridden in a 700rwhp Supra and a 400rwhp Supra...crazy enough, felt damn near the same.
Before I go and try to find the facts, don't you find it sort of weird that Matt's dyno DECREASED when his MKII has went through changes for the POSITIVE? :nono: Hold on, Jason. I'll get the info.

horsepower and torque will always cross at 5250 rpm. it is a mathmatical equation hp = (rpm * torque) / 5250. only time they will not on the graph is if the hp and tq scaling is not the same. i.e. hp is graphed at 500hp while trq is graphed at 450ft/lb.

 

[Nick M]

Post your scan in the turbo sticky.

I had never heard that about the hp and torque intersecting, but mine does it at exactly 5200 rpm.........lol

Horsepower is calculated as follows.

HP= torque x rpm / 5252
