ROFL, these guys build motors to race in certain classes. So, can I build a motor that is faster around a track then them? Yep! I don't have to follow the rules of a racing class its a big advantage. Also, I have seen one Jon's customers 968 turbo cars with so much money into it it was rediculous and it didn't impress me in the least in terms of its performance.

But its so based on driver skill more then the car also most of the setup is there own but the car could go faster (in its class). I also think Dave holds many records in his class but its not really the point.

Yea, but not many of our customers run anything faster as its just not logical in a 944T. If they are running in a faster class they are going to be using a different car to get the job done as it makes more sense.

So 951's don't have lag? Any large turbo car has lag its not just the 951. That being said the exhaust on a 951 (crossover) does not help. If you want to make 600whp your going to get lag from a turbo its that simple. That or you could make 600hp without the lag its a choice we can make on our 944 cars and not one you can make on smaller displacement motors. If you try to do what I am doing to say an 4g63 your results would be extremely poor actually it would just surge.

Even the people doing the road racing are building the cars wrong and are missing the point. The 951 is still a lag machine on the track and even with 400whp cars with less HP will run faster times as they don't have the lag to deal with from the turbo. I see 944 turbos get blown away expecially coming in out of tight corners into short straits they just lose all sorts of time. .
And I got on RENN LIST and asked if you can move the turbo and if you can how?
It’s kind of nutty where the turbo is but once you look a little bit deeper and realize that there is no room on the exhaust side unless you do away with your head lights (and even that is still far). But I was hopping to find some one that has come up with a kit for that to do away with some lag. BB turbo + a mount kit right on the headers = less lag.
I have to say this thread is Great.

Three Wheelin'
Just thought I should point out that another ball bearing turbo option is the Precision Turbo SC series lineup. The nice thing about those is they are Garrett based and built mostly off of Garrett components (PTE has a few of their own proprietary wheels). They come in journal bearing and also have the option of a DBB center section for most of their SC series. The nice thing is, the center section is a regular T3 center section and isn't much smaller like the GT series center section. I'm guessing they are using Garrett's new T3/T4R center sections, though I don't know that for sure. One thing's for sure though, they have a much larger selection of wheels than the typical T3/T4R's on the market. They are just a bit cheaper than the GT series, though only by ~$100-300. Because of the standard sized T3 center section and the availability of a 4 bolt T3 exhaust housing, the center section could be installed on the car with basically the same minimal mods required as a LR turbo or various others as most of them use T3 center sections anyways. Also, if you search this forum, there are pictures showing that the Garrett 4 bolt T3 exhaust housings actually have the same turbine outlet bolt pattern as the KKK housings, so the downpipe can bolt right up, though some grinding may be necessary. Definitely not a 100% bolt on, though it's one option.
Strangely enough, a thread on the 930 forum showed that K27 exhaust housings literally have the same inlet and outlet flange shapes and bolt patterns to Garrett T3 exhaust housings, to the point where people have literally just bolted stuff like Gt35r's on to their stock exhaust components. I thought that was interesting, and it made me wonder about installing a full K27 on these cars, not just a K26/27 hybrid. The K27 exhaust side is not massive as some might think, and is comparable to Garrett T3 stuff with housings being closer in size to Garrett .63a/r or .82a/r T3 housings (I forget which).

Its one of the reasons that S2 cars can hand it to a turbo car on a lot of the tight tracks. Also, alot of the 944 turbo cars cannot produce big numbers because the way people build them is pants on head retarded.
I only posted this in response:
You really have to get out more. Making the statement that my motor or similar build was built pants on head retarded is just silly. Please enlighten me on how to do it properly. I will listen. I am an open book both ways.

My next question for him would be what he did to those cars that isn't "pants on head" retarded that Milledge and others apparently don't know how to do on their cars. However, seeing as they are stock odds are that he did nothing. Actually I'm waiting for his explanation for his apparent connection to Steinel - if there is one.

His cars have not been to Steinel for awhile as far as I know we have been doing all the work on them in the last few years at P3 Automotive.
