Going to the dyno today, any guesses?
I am going to Stage 6 here in town today to get my car dyno'ed.
I am hoping for high 200's at the wheels, but we shall see. I will post pics of the dyno and the slip tomorrow. |
Stock ports? What kind of exhaust? How much boost?
|
I guess 101hp.
|
Im with ya on at least 200. Its a Cartech turbo kit right? Arent those rated at almost 300?
~T.J. |
A T76 on possibly a 12A??!??!? Good Lord!
|
i'd bet you're over 300....I have a Cartech kit on my 13B and Corky Bell himself rated my setup at over 350HP.
|
I would say not more than 200 rwhp, its measurement that matters not rating. What is in the Cartech kit?
|
just for fun i'll guess...i say 284 hp and 208 torque
|
Did you forget to go to the dyno?
where's the numbers? |
Okay boys and girls, can you say "My car is slow"?
186@7000rpms 8lbs. Don't laugh too hard, you might burst a vein. I was very surprised and very embarassed. I was lean (13) at low rpms and okay (11) at high rpms. I am thinking about turning up the boost to about 12-14lbs, rejetting the carb, changing the plugs and trying it again next week. I was in such shock, I left without paying. I will be going back today to make payment for making an ass of myself. |
What type of porting job do you have?
-Error |
186 hp is nothing to sneeze at in a 2500 pound car. You car is probably quite fast indeed.
|
None.
|
Coming from someone who admittedly knows relatively little about turbocharging, your dyno #'s aren't far off from what I expected. On a stock port I'm not surprised with those #'s at all. That said, 186rwhp is probably ~twice what your car had pre-turbo at the wheels. I don't think you did bad at all, certainly nothing to be embarassed over. Cheer up :)
|
Thanks for the post man, I was just hoping for better numbers.
If anything, I am determined to get into the high 200's and I am going to work on it starting today. |
I know the turbo has tremendous potential, but I just installed the air/ fuel meter the night before and really have not tuned the carb perfectly.
The guy down there (Tracy), gave me some advice on jetting, so I will follow that and crank the boost, probably to 14 lbs. Does anyone know what the max boost on a T76 is? |
i wish my car made 186 to the wheels. That's pretty damn good for stock porting and a blow-through system. (Not that i really know much about the stuff) but after tunning properly i wouldnt be suprised if you hit the 200 mark. Not bad for a "bolt-on" job.
|
If you get that thing street ported and tuned right those HP figures will be close to double your previous amount...believe me I know. Good luck man, don't be so hard on yourself.
|
I just installed an MBC, how does this thing work?
Is all the way in full boost or all the way out? |
I think putting more stress on your motor by turning up the boost will hurt in more in the long run with those stock exhaust ports. I don't want to see another first gen on the side of the road. If you want to see a great increase in power with your current setup...get it ported. Even a mild street port will be better then forcing those small exhaust ports to do more work.

The guy I bought the car from said that the motor is ported, and it lops on startup, but I looked at the intake ports and they looked stock.
I am guessing that this guy would have at least the exhaust ports ported running a turbo. |
Phew *wipes sweat off of forehead* I feel much better. :)
I really don't worry much about the intake ports as much as I do the exhaust ports. I'm wondering are you getting an turbo lag and how is your clutch doing? (I didn't read through all the replies so I apologize for coming into this discussion a little late.) -Error |
There is some lag, but this is my first turbo car, so I have nothing to compare it to.
Dual friction clutch is holding up well, it was basically new when I bought the car. Traction is a problem though, keep spinning the tires. |
Shit, I would be happy if I could hit that number with my Weber blow through Im planning at 8 PSI.

186rwhp at 8lbs boost is reasonable with a stockport. Pushing up the boost further without dowelling may not be a good idea. You will also be getting to the stage where driveshaft, diff and clutch modifications should be considered. Without a good intercooler I suggest 9-10 ib should be your max boost with another 2 with a frontmounted IC. In an early response I suggested 200 hp max for your set-up, with a little fine tuning this should be possible.
OK porting will give you more power, but a strip down and port job is an expensive option at this stage |
