Well all I can say is good luck to you man and be sure and document everything. I will be interested in following your progress and how the car is doing.

Yeah it will be documented, i am considering leaving my car alone and having a project car for this, which is going to be one of customer cars probably.

Consider this guys, why is that a low end sports car motor like the 4g63 can make close to 800hp without problems with only 2.0 liters while a high end p-can motor cant with .5 more liters? J/k but you know what i mean.

Sure 450whp will reduce the life of the motor. But so will 400, or 350, or 300...

I went drag racing as well as hot lapping (30-40 min sessions) at those boost levels. That's WAY more abusive than day to day street driving.

Food for thought .

The zebra 951 race car that was 700hp. How many track day's did it last before rebuild's?

I would be very interested to know this and lithium it might be beneficial to you as well. We could really see what the limit's of the stock motor are and how long they would last under such harsh condition's.
If you are refering to the Huntley car, no , it never had 700 Hp, that was just clever marketing.

An engine that lasts is in my definition an engine that can handle an endurance race. Or a couple of days on the Nürburgring.
Unfortunatly there is no 30psi turbo engine that can take that... No matter how much rice it gets

Lets be open minded guys lithium is spending his own money and maybe we can all learn something.
Back in the late 1980's people were probably saying the same thing about getting 400hp out of our cars. Things move on! If it all goes **** up its nothing new. If it works out, thats development and we have all learned something! Good Luck Lithium, you can't stop progress!

Well, I'm sure it can be done but at what cost ?
If money is not an issue why not. Maybe lithium
could source for a Norwood builded 968 turbo
engine.

Man some of you guys crack me up... borderline talking out of your asses .

What makes you think an 18psi 360whp 951 WOULD survive the same conditions? Or what makes you think a 28psi 450whp 951 WOULDN'T survive the conditions? Have you guys tried this?

Point is, I pushed my car hard, and it survived. I'm sure you've all see my videos. Hell, in Oct of last year, I ran my car HARD on the track, no cooldowns, lap after lap after lap, track day after track day, trying to blow up my 2.5L motor without success (I had the 2.8L going in so I just went all out). I was unsuccessful in breaking anything. I still have a working 2.5L block sitting here.

I have *PROVEN* reliability at 460whp with a stock block. Who's to say that's the breaking point? Lith is aiming for 500whp, IMO a very realistic goal. Until someone breaks a stock block WITH proper fuel/timing/tuning, we will not know what the limit of our blocks is, and which component is the weakest link. Most of the modded 951 failures are contributed to poor tuning, or poor maintainance, or problems like rod bearings that affect even STOCK 951's.

Rant over .

Rage2, I must agree with you. My race/development car takes all kind of beating (400-450+rwhp) and the internals are all stock.

Well,

All I can say is that I have seen an 3r45ftg engine running at 70psi on street fuel. I also saw f5u62c874k engine running over 100psi of boost on 100 octane race fuel.

In the famous words of Vanilla Ice: "Rice, Rice, baby"

Easiest way to spot a ricer: they spit out engine code. In the ricer world, if you know some stupid numbers, you all all knowledgable.

Lets just put it this way about ricers. I helped one fix his nitrous system becuase he couldn't get the nitrous/fuel ration correct. I somehow "magically" made a #32 jet from his #20. Hmmm. He couldn't figure out how I knew how to do that. I am just witing for the ricers to claim they are running #500 jets. In fact, I have told ricers that I was running a #500 jet and they are so stupid they couldn't even figure it out. There typicalyu comment was "no way you were running a 500 shot". I told them, no, I was running a #500 jet.

Lithium, you know, if you have a #500 nitrous jet, you could make over 1000rwhp (at least for a little bit).

Yes, this is sarcasm. But yet again, a supra is involved. Hmmm. Coincidence or not that these threads seem to be turning into 1100+ hp supras. Hey if you like rice, go get some rice and leave us kraut eaters to our kraut, brats, and beer. I am sure rice and rice beer taste just as good as a nice hearty meal with real beer (note: REAL beer does NOT use rice). And yes, no matter how hard you try, rice will never taste like a nice wuerstchen.

-Dana

Ok, so how much power can we push on a stock block/internals using pump gas 93?

And what do we exactly need? I think I might try this out during winter break.

If someone breaks down exactly what I need I'll give it a shot.

Would a Vitesse stage 2 kit be able to handle that power?
