I wonder if you'd hit 200 whp on a DynoJet... Mustang dynos are known to be on the low side

We started hitting the max of my stock injectors, so backed off a hair to get it where it is. I want to say we were right at 204 at one point. At the end of the day, its just a number, and I'm real happy with how it runs right now. I'll save the numbers for the Boosted B18C1 motor when I get started on that.

It's very depressing to see that especially for very mild basically bolt on set-ups the stock GSR motor is barely making it above 170 whp.

AFter so much money invested to even have only put up those kind of numbers... very depressing...

Such as my numbers.

94-95 Integra GSR
around 140k Miles
Skunk2 IM
DC Ceramic headers
Denso Iridiums
Straight pipe to a no name straight through exhuast
I believe it has a "chip" in there, thats what I was told from the seller from when I bought it. I never got around to investigating it.
Exedy Clutch
Findaza flywheel, I can't remember what weight, I believe around 12 lbs or there of.

In my hay days of "racing"... it beat alot of cars I didn't expect it to, even a turbocharged sohc civic on a 40 roll(but then agian, it's a sohc right?)

In any case when I finally was able to throw it up on the dyno this was the results.

Don't mind the clear signals, they came on the car when I purchased it and this was 6-7 years ago.

148whp max? Wow... With drive train loss that's barely the stock 170 hp! I was shocked and hopeless.

I think for us NA guys who are going with the mild bolt on are better off buying a b18c5 and just dropping it in and calling it a day.
If you look at your air/fuel ratio it's way too damn rich. It's dipping down into 12's or high 11's afr. That's dipping into Boost afr territory. That's why it runs like ass. Aim for a constant 13 afr @ wot for N/A. That should bring your car about into 160ish whp. Your map on the ecu chip is crap just by looking at your torque curve. It's suppose to be a smooth incline. Your better off running a stock gsr ecu or converting it back to stock if your running a chip gsr ecu. If not get it properly tune cuz I wouldn't run that chip smh...:thumbs_down:
