We at DC Tech have done 30 to 40 of these modifications and they have to be tig welded to be done right. Typically mig on cast aluminum doesn't work as well as tig because mig has to be run to fast to keep up with the wire that is fed and the heat involved is not great enought to get proper...

That would make sense but it is not the case. I have emailed NHRA for a rules clairification. It is always up to the track to enforce all rules but there must have been some major problem some where for them to do this.

A friend of mine went to our local track (KCIR) in Kansas City for the Friday test and tune and was promptly told that he would not be allowed to use his laptop during his burnout or run as per NHRA rules. As I read the rules, the use of computers are not allowed anymore. The definition of a...

Maybe that is why the pistons are so annoying. I did have the Weisco recomendation sheet and it did say the clearance should be .005. They didn't give a range and they would probably rather have them a little to loose than a little to tight.

I fired the motor in Dec. and have 1300 miles on it now. I probably have 40 to 50 WOT street blasts and 3 passes down the track (18# to 22# of boost). I even took the pan off and checked bearings. They were fine. I have run three compression tests with the last being tonight and they were all...

I recently built my motor with weisco pistons (.020 over). From the first instant the motor was started it had a diesel sound to it. I had a number of people listen to the noise and they all came to the same conclusion. Piston slap. My machinist said he honed the clearance to .0055. This is only...

POSTON has them.

I did the GNttype thing about 4 or 5 years even though I talked to John Craig about the benifits of this work. He told me it wouldn't hurt anything but not to expect much as the stock turbo would only flow so much air. I want to think it helped some as I spent some time in this project. I did...

We at DC Tech make these detent brackets. They are made out of 11 ga. T-304 stainless steel. Let us know if we can be of service. Hours are from 7:00 am to 3:30 pm central time. (816 842 9090) Ed

Julio, We always knew you were the MAN, now everybody else does. Are you ready for some RIBS? See you there, Ed

Actually I was looking for the whole assembly (shaft and rockers). Thanks for the info. Ed

Bill, Thanks for the response but I finally found one at Poston's. It was the last one they had. The manufacture (Federal Mogul) told me that they had zero in inventory and had no plans to produce any. They did say that they did have a limited supply of one of the rockers but the other one had a...

Looking for the HD rocker shaft assembly that turbobuicks use to sell. Anybody have a set (both sides) that they arn't using? Thanks, Ed

The stock turbo, an Eric Marshall chip, and a Razor alky kit and the sky is the limit. If you get an RJC boost controller the spool will be quicker than anything that you can imagine. I ran 25# of boost with the stock turbo and had almost no knock after a lot of tuning (about one year). This is...

I have a similar situation with my new motor. A diesel sound on first start up but after warm up the noise is quiter but never going completely away. Everybody that I have talked to says that the pistons have more clearance that the manufacture requests. I have Wiesco pistons that have a...
