DynoCharts: K26-8 with LBE and Guru chips
Just had my car dynoed for the first time. I was interested in what some of the forum members here think about the results, based upon their own modifications.
Here are some of the details: 1988 951 Turbo (M44.51 engine) KKK 26-8 stock Turbo S turbo Lindsey Boost Enhancer set at ~8 psig to improve spool up Stock boost management (Cycling valve, etc.), which peaks at ~15 psig, then tapers off to around 12 psig at redline Guru chips on stock setting The test was done on a Dynapak setup, with three 3rd gear pulls. No changes were made between tests. My wideband AFR gauge was showing 11's, going up to around 12.5 on the high end. Here are the results:   So I guess that the car is making an additional ~25HP more than the stock 247HP at the crank? Any other observations you guys can make here? When do you think I am hitting full boost? They supposedly logged the boost during the pulls, but that is (Obviously) not on the current graphs. I have asked them to send those to me if they have them, we shall see. Cheers, Keith

I dyno around 275 hp / 300 ft-lbs at the wheels with a similar setup (1986 951 with a K26/8 and Guru chips @ 15 PSI), but I've removed the stock CV and have pure mechanical regulation.

Wayne, I can't make it out to PIR this month, but plan to be there for the January event. The PCA event on the 4th was cancelled, so I am going out to INDE next weekend (
 ) for the PCA Instructors training. I am expecting that road course to be awesome!Regarding the pulls, I didn't do them, the owner did them. Wayne also had his done, and was putting out a lot more than I was. I guess that the LR 340HP kit helps! He told me that it was a 4th gear pull, but when I was watching it looked like he was in 3rd. Since they are a tuning shop, they have a lot of experience with modding turbo cars. He indicated that there was some pinging going on with the later pulls, as the car got hotter. The AFR's were in the 11's to max 12.5. What is the highest AFR that you would consider safe for our engines? I was thinking that 12.5 was probably OK, but they were thinking that it should be in the 11's to be safe. Cheers, Keith

I made 307rwhp at 16.7lbs and 325 at 18.34lbs. I am running a LR 340rwhp kit with 60-1 hi-fi. I thought it would make more power though.
From my understanding at WOT AFR should be 11.8-12.2. I think 12.5 may be on the edge of being lean. Last edited by v8killer; 11-16-2010 at 06:32 PM.. |

Wayne, maybe you can put up your dyno charts here as well. What else do you have on your car? I am thinking you have a cat delete, maybe 3" exhaust, MAF, dual port WG?
I am interested to see the differences. BTW, I just got the boost logs. It's interesting to me how much variation there is from pull to pull:

My Lindsey 340 kit has MAF, Mafturburner, Max chip,55lb. injectors,3" exhaust, 60-1 hi-fi turbo and I took off the cat. I don't know about the wastegate.

Thanks Peter. That is what I was looking for.
I think that I might up the gas via the FQS, or probably more effective would be to get an adjustable FPR. @Wayne: Based upon your boost curves, I would say that your have a DP WG, otherwise your boost would have dropped more at the upper end. Cheers, Keith
