just got back from a short dyno session. we put down 155whp on a mustang dyno with ihe and some playing around with crome. i read the dynojet reads about 20% more than the mustang but i was just wondering what the stock output (on mustang or dynojet) of this motor is so we can compare before and after. we had almost a perfect 13.3:1 afr from 6-8000rpm. stock afr was in the 10's

 

Did you adjust the A/F with crome or an FPR? I think it is likely to get more into the 160's range on a dynojet. A local tuner got 18whp on a stock GSR

 

afr in crome. we datalogged 2 runs. it was like a special for like 10 bucks a run or something. we had 154 whp on the mustang so is that like 184 on a dynojet? i just want to know what the average stock gsr no bolts on at all puts out so we can see how much power we gained

 

Well, if a stock GSR can get 18 whp from hondata then I would imagine you could get about 25 WHP assuming your engine runs good. I can testify that GSR's are capable of 145 whp on a stock motor with Hondata. I know crome is the ****, so I think you are very close to what you should be at. With the right conditions, a good tuner, and more dyno time I think you'd be able to get about 160-165

 

so that is 165 on the mustang then? my friend and i are tuning it. we havnt touched the ign yet. and i think there is still more room for peak hp. thanks

 

So you can make just as much power if not more than an ITR with a Hondata and an I/H/E on a GSR? That does not sound right but I guess anything is possible

 

well we have spend countless hours datalogging o2 and making our own cold air intake and 2.5" exhaust. we also got the ebay special header w. 2.5" collector. cylinder compression was around 220psi so the motor is in decent shape. if i have time ill post the video we took. i dont have a scanner so i cant copy the dyno graph. this was done on 91 pump gas.

Yes, anything is possible.

 

I just can seem to soak up that a GSR can make up that power diff from the R, the R has a higher redline, better valvetrain, better cams, higher comression, closer ratio tranny (doesnt matter on the dyno) and weights less. Can we agree that a GSR w/ 165 whp wont beat a R with 165 whp at the strip?

 

dont get so tied up on numbers and magazine racing...youll always lose...what if i told you i pulled a 93 trap in an LS with just a transmission swap?? throws a wrench into that magazine racing concept doesnt it...

 

The tranny is really what makes an R an R.

I am not, having owned BOTH cars stock at one time, I can not comprehend how a GSR with an I/H/E could keep up with my R when it was alive, the best time I ever had BONE Stock in my R was a 14.61 @ 98, this was full weight with half tank of gas and a 220lb driver. I have never seen an GSR do something like that with an I/H/E. But hey, who knows... I sware my 9:1 GSR right now non-turbo pulls harder than my R did and I am running an LS tranny

 

give that gsr a type r transmission and watch the r start sweating

Nice sig BTW

 

I bet, I am in the process of searching for a GSR/ITR/B16 gearset for my car, I am tired of shifting out of 2nd gear near 80mph

 

That sucks You are turbo though right? Would shorter gears be optimal for your size turbo?

I would love to do a hybrid B16 3rd, GSR 4th (to keep me in 4th in the traps) and keep my LS 5th and either keep the FD's or swap them. BTW top speed of an LS tranny @ 9k in 5th gear w/ 205/50/15 is 203 mph

 

That would be sick

 

well this is how i see it. looks like gsr's are making 130-135whp stock on a mustang. so well say my friends made 135 on the high end. this is with no intake, or exhaust, chip etc. straight from the factory. with a h/i/e im sure thats good for another 10whp. i would have loved to do a before after but we never got around to it. i might do that with my ls vtec when its done. anyways that about 145who now and im sure we can make 15more whp just from tuning so im aiming at 158-160whp right now. i know there is a little more room for improvment. on our last tuning session before the dyno we could feel it getting a little slower so i think i might have taken out too much fuel. i think its going to make the most power at 12.8-13.0:1. now its at 13.3-13.5:1 according to the logs. so ll have to do it again. we had a 93mph trap. were going to set the rev limiter to 8800 so he wont have to shift to 4th. we might get a 93.5 or even 94mph trap speed . well see

doesnt a b16 tranny have the shortest gears? my friend has the gsr tranny. shorter gears would def be nice

 

Keep us updated. I need a tune like no other but I've got this CEL that won't go away

 

speaking strictly hydro....b16 and type r have similar gearing...the 1st gear of the hydro b16 varies slightly than the type r...but they are all about the same...just type r has lsd

what cel? do you have a gsr?

 

I HAD a GSR... I have a JDM H22 with Hondata and some other stuff. I can't check the CEL until I have a cable for my laptop

According to my local honda expert and many others, all hydro's 1st & 2nd gears are the same
