This motor was built after the 3.6TT that went into Stephen Kaspar's famous Monster 930. Here's some info on that motor http://tinyurl.com/yapcf65

The biggest difference between my motor and that motor is that my motor has the turbos on the sides to allow room for optional cats and a muffler.

Hi Keith, a normal built 993tt engine with 8.0:1 compression, K24's and 1.0bar will produce around 450bhp. To get to 520ps (513 "flywheel" BHP) on a 993tt you need special K24/26's, 3.8RS cams, and good programming running a max of 1.1bar!

Stephen is a nice guy, but there is NO way that engine can make that power at that boost level, with that compression ratio and "just" K24's. It must be a typo, i would even question 507bhp!

Johnathon - Is this 450whp?

Seems like a really good deal, no. of miles on the engine?

FWHP Yasin, basically a 993tt with X50 kit running the K24's will net around 450bhp. Remember that's at 8.0:1 compression ratio, this engine is 7.5:1. I love reading about big power engines, but lets get a reality check here, a bit of boat-tailing and some nice valve springs with a set of cams isn't going to spit out 600+ bhp, it's simply silly

Where r u locate and what is the price?

Good luck with the sale Keith, I have no affiliation with the OP.

Less than 100 miles, the motor was finished a while ago by Stephen Kaspar, but the install was never completed locally (I should have had Stephen do the whole thing from the beginning). It's only been driven lightly around town during the initial EFI tuning. It's basically a new motor.

A 3.3 still running CIS, with 7.5:1 compression, SC cams, .9 bar boost, decent intercooler, turbo, and exhaust will make 450 hp, maybe more, at the crank (see Bruce Anderson's Porsche 911 performance handbook, also 930 experts correct me if I missed something on the the classic build).

Now change SC cams to better 993 sport cams, add head work, EFI, more efficient intake, exhaust, turbos, (more efficient everything), change 3.3 to 3.6 liters, change .9 bar to 1.0 bar and I don't see why 607 hp isn't just possible, but unavoidable.

Firstly i never ment to be obnoxious, reading my second post does sound a little that way doesn't it, sorry Keith! I'm happy to be corrected when i am wrong, I'm certainly no expert!
But the engine in question is basically the same as a 993tt engine with slightly lower compression, running a pair of K24's at 1.0bar, is that right? Or is it in fact running hybrid 24's with large (K26?) compressor wheels, and 1.2bar? Because that is what is needed for "less" than that amount of power on the 993tt platform!
I'm sure it's a lovely engine, and worth every penny of it's asking price, but a real 607fwbhp is not possible with what has been listed. That's not speculation it's a fact! Now if Stephen was to pop up and say "hold on a minute, the list above is wrong, it has very special big turbo's and it boosts to 1.3bar at peak torque" or something of a similar vein, then it would all make more sense!
Lincoln, if i've said something to upset you on another thread why not say something on "that" thread? Surely it would be more constructive there?
Keith, the 3.3 on CIS that you mention running 0.9bar and 450bhp, what turbo was on that? A K29 or similar? I don't have Bruce Anderson's book. I didn't post to rubish your engine BTW, but more to highlight what i thought was a typo

J, you haven't upset me directly, it is just that collectively you have been a bit preachy. I apologize for jumping off the handle at you, however, it seems you get rather negative on other people and their horsepower claims or whether or not their car is a Ruf or not. It is well settled fact that air cooled Ruf VIN cars are very valuable, and that everything else mine included are very nice cars with great bits and pieces that will sell for what the market will bare. I would like to delete my earlier post and I humbly ask that you do the same so as not to sully Keith thread and you and I can discuss RWHP and Ruf cars via PM or on another thread.

JBL930

No need to apologise, you are welcome to speak your mind, i clearly do

From what i can gather Lincoln, i have only commented on two Ruf cars, one was Olli's BTR that was advertised as 475BHP and it was still on CIS, I just wanted to point out that was incorrect, which it was. On another thread a chap mentioned his car had a BTR engine, i started my response with "I am no expert, but i thought all BTR's were 5 or 6 speed?" Then he posted some pics showing the Ruf tag, and you pointed out that they did some BTR conversions keeping the 4 speed box, which is great. I, and i am sure others, learned something there. I can't see where i was out of line in either thread? Maybe you are reading what i am posting in a hostile voice and making it sound worse than it is?

I think it's important to point out obvious misinformation, some guy may have bought Olli's BTR thinking he was getting a 475bhp car, i guess prospective buyers should do their own research, but these kind of forums are here to help right? Olli's car was stunning, no doubt about it, whoever bought it is a very lucky bugger, but it was incorrectly advertised and after he did some research he admitted so himself!

The engine for sale here is no doubt a belter, nicely built by a well known pro! But again someone may buy this engine thinking it will "actually" be 600+bhp, when with 1.0bar and K24's is a complete impossibility!
In retrospect i could have tackled it better on this thread, maybe asked "how" 600bhp was achieved with such low boost and K24's! In all honesty i didn't realise it was actually Keith's engine, I just thought it was a random link to a sale, and if i have caused you any inconvenience Keith I appologise! Maybe spend a while on the 993tt forum here on Rennlist and do your own research, you will see for yourself then that the power claims need to be revised. Gladly over there they are pretty good at keeping things in check reality wise.

Dyno sheet would clear everything up.

Olli's car is a veritable beast. I have had the pleasure of driving Olli's car albeit after the Motec EFI transformation. Olli still owns his car, he never had it listed for sale it is now resting quietly in Finland. I don't recall him ever listing his car at 475rwhp on CIS.
