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 *** of myself.

 

What type of porting job do you have?

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.)

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.

 

****, 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
