However, with 600 HP in a 911, I would argue that this type of car would be very difficult to autocross

Another good point, but as sad at its sounds I did watch one of those DE events or autocross I really dont know the different but the silly one that you go around cones:rolleyes: anyway I saw a lot of 911s 928 and other few cars they even had a few 996,993 with all kind of suspension modififations at the end of the day......................the winner was a stock mini cooper:( so you can only imagine how I felt after I witness that.:rolleyes:


I think that Porsche has always balanced power with control and reliability for the street cars.

reliability for the street cars ,I have wonder about this for a long time since I have heard so many stories as an example it appears that the list is endless with problems or bugs that the 911s have suffer thrue the entire life from head studs in one series to valve guide wear in anothers to even the latest must modern cars so the question is in all honestly can we consider them "reliability for the street cars."


:( :)

Juan: the sound from my dual B&B setup without cat's is enough to discourage most. I had a new M3 pull up next to me, rev his engine thinking I was a stock 911. I obliged with a loud deafening throttle blip. When the light changed...he waved me on.
By the way....I applaud your efforts.

Thanks must people dont apreciate it but hey Im use too.;)

BUT NOT to sound like a broken record but we have gone WAY too far in this subject, the subject is not my car or my hp goal or supras the subject is to HELP a Pelican Member to find his 500hp so PLEASE lets help him and move away, heck lets start another thread.;) :)

Ok. I think the most cost effective thing for him to do would be to find a cheap 3.6 EFI turbo motor. He should be able to hit 500hp fairly easily. Another alternative is to go with the 3.3 and do the Carrera intake modification (modify heads to twin plug) with TECIII. With the right cams,3.4 P&C's and exhaust, 500 hp is not that hard to hit. The main problem is finding the engine core at a reasonable cost...that's kind of a crap shoot.

500 hp is not that hard to hit. humm......:(

It seems that a lot of people think that this is a easy task:rolleyes: which could be if you build this things day in and day out,the problem is finding the correct combination that will produce this power and will stay together, lets said as an example Cams...well if you ask 100 people you get 100 different answers,so ok we find x cam and we hit 500hp but on the street or track Im getting kill because no much lower end or too much top end or whatever the reason, so a simple task of choosing a cam can make it or not,thats just an example if you go with choosing a turbo (in my opinion is even worst) but remember this are ONLY my points of view,another thing is do you know how many people claim that they have 500 600 700 hp? you be surprise how many people I have e-mail asking about the dyno sheets 90% of them have no proof of what the car is making,if you drive my car with 300hp and I tell you is 600hp must people be like damm:cool: another example is how many people with 930 cars want 500hp then half way too it they find out that is (according to everyones) impossible with that fuel system then the intake then this and that if half of that people know about that they will never go for that much hp,bottom line be carefull on how you go about building your 500hp engine.;)

Yes easy is a relative statement( I did not say cheap). I think we have a few people on this board that know how to get to the 500hp mark with a few tried and true combinations. I have been collecting my parts for over a year, and am still working on my budget.

You bring a very interesting point since this has to be the most visited Porsche forum, Im wonder how many people out there could post their 500rwhp+ dyno sheets,it be very interseting if we have half a dozen of them:rolleyes: Better yet I will open a poll, I know that when we post anything HP Junkie related A LOT of people look so lets see how long we can keep it before it dies(I said by the end of the nite she will die no more than 2 ) ;)

Most people only have relatively stock cars. Probably 5% go the extra mile. 5% of those 5% go for 500 with twin turbos...

Hey juan, since your a street racer/drag racer you should contact speed force racing. It's owned by a gentleman named tim richards, hey hates track racing but like street and drag stuff. I believe he was featured in poplar mechanics for building a supra that put out 1200 RWHP and like 36psi boost or something. It's sick and he'll take any chance he can get to make a mean 911 if he's got a customer with some cash. No affilition BTW.

building a supra that put out 1200 RWHP and like 36psi boost or something :rolleyes: :rolleyes: :rolleyes: :(

For sure my next project will have to be a supra:(

Do you have a web site for them? no that I have any $ left since I already took a loan on my 401k then a second morgate,BUT I can always use more hp advisors;) I dont need 1200hp but I could use 900rwhp;)

"no that I have any $ left since I already took a loan on my 401k then a second morgate"

I suspect that you may get some financial advice from others on this move, but I for one say it's your money so live it up. 900 HP is insane.

As usual, great posts Juan. Keep the HP faith.

I personally feel that the Lexus aluminum V8 would be a fantastic turbo platform. 6 bolt mains, forged everything, etc.. There ya go, I have set the table eat up.

I don't like Crow...anything else on the menu?

My friend those are OLD NEWS,and so the 3 rotor rotarys and the mitsu v6 twin turbo in a galant, and the list is endless......... and by the way Im not here to start a pissing match If you are like one of those other guys that suffer from the MID LIFE CRISIS Please see a doctor...........

Juan, my friend that owns a shop spent some time on the phone this week with a Turbo specialist. The guy does Turbo work for Porsche motorsports. We have had several turbo failures on 600+hp 911's that used k-27 and k-29 hybrids. This fella told us that the limit for those turbos is abou 450 to 500hp (single turbo apps) We have 3.8 turbo that sheared the impeller nut clean off. This fella told us we were over revving the turbo and even with blow off valves the shock to the impeller on closed throttle probably caused the failure.

He recommends K33 or K 36 turbos for high hp Porsche engines.

We road race our cars so I believe the applications for drag racing and road racing will be different. If you set up your engine management to have flatshifting and "staging" you may make some serious hp with these turbos...

First my apologies as we have fail to start another thread and we have hack this one

Tim I THANK YOU very much for your opinion,

if we move to the turbo dept,PLEASE BE AWARE that Im just pointing out what has work for me,I have spend the last 7 months day in and day out looking and researching turbos (just like I did turbo vs supercharger and that was OVER A YEAR) so of course we can go around and around on what turbo we should or we can use, in the 911 world must people swear by this kkk and fantastic because then we get into the match of garrett vs kkk,so must people install this kkk and life is great my hats off,I am walking a different path I swear by garretts so this days you could go into the garrett,kkk,GT you named,since my application appears to be a little different I have NO ONE to ask "hey what can I use to run 1/4 mile" must people will sell you a "basic turbo" to start with, so in my case I have choose to do my OWN R&D on the turbo dept, as we speak I have gone thru 3 turbos with the same set up all of them dyno and Im working on my 4 one very soon,my point is that FOR ME at least is not that easy just to purchse a turbo.

Now if we move to the engine management thats another story all together as Im running the Factory Motronics but this will be replaced soon with some source of mangt system,make no mistake this are all very easy things to do but must of the inf is been keep secret by must tuners,but this is ONLY in the Porsche world if you move to a mazda or supra you have zillion people to help you and by the way this has nothing to do with drag racing a 911,so at the end of the day it all may sound and look easy BUT some of us that are pushing hard to extract as much hp as possible is not that easy....;) Of Couse thats just My opinion;) :)

"and by the way Im not here to start a pissing match If you are like one of those other guys that suffer from the MID LIFE CRISIS Please see a doctor..........."

huh??????????? What did I miss here?

Yup, your friend's turbo specialist is right on the mark. Here is a chart that compares a lot of different turbo types. For those of you such as myself that can't read japaneese the turbos are broken down into the following brands.

There ya go, I have set the table eat up.

but I for one say it's your money so live it up.

When I read staff like this I wonder if the person is been a "smart ass" as I been verbally attack here in many many occasions and thats one of the reason why I dont participate as much as I used too or could like too,been a sensitive person I am I get offended very easy so If you were acting in GOOD FAITH My deepest APOLOGIES as I MAY have misunderstood your point, I was just under the impression that another attack was coming my way, so there you have it no big deal.

So we move on and for all of the fellows that are following this thread I present you this link

www.bobnorwood.com

when the page opens go to the left and "click " on 4000hp

As you will see a 4 CYLINDER 4000HP Engine so if you see this 900rwhp could be a cake:rolleyes: ...........maybe;)
