HP Junkies Guesstimate Hp ?
For the SMALL POPULATION of HP JUNKIES on the Board my proyect is 6 quarts of oil from been start my friends and my self are trying to see who will come the closest to the HP at the dyno to be done in a few weeks the final combination was.
Born as a 3.2 3.3 P&C Manhle Pistons Tops and Sides,Rod Bearings all were coated Heads Ported and machined to accept Niro Ring, 3 angle cut+all new valve guides Cylinders Machined for the same 944 Turbo Injectors 2 Parallel Fuel Pumps Fuel line open to 8mm Evo GT 2 Cams New Cam Ramps Tial Waste gate Tial Blow off valve Raceware Rod Bolts and Cylinder head Every nut and bolt removed was reinstalled with a new one Aluminum Pressure Plate(10pnds) Six Puck Custom Clutch Full Bay custom Intercooler Greaddy electronic boost controler EGT Gauge Air in/out of turbo Gauge Turbo TO4B( to be replaced soon as I decide with what) Intake Manifold Ported Racing Valve springs with titanium keepers Custom 3'' Exhaust Custom Chip Maybe I forgot a few things,I have 4 friends to vote for 500hp,one 450hp,my self no clue  who wants to Guess?P.S. Free cookies and Tea for the winner  Regards Juan 3.2 Undercover Soon to be BORN! |

I'm guessing a kabillion. Is that more than a gazillion? Heck I don't know I'm drunk....How pathetic am I. I come home from the bars and the first thing I do is check Pelican...

From what I can tell from your list, you are still running CIS? If so, I'd guess 450 at the crank. Too bad, too, because you've got enough safety margin with the rest of your stuff for 550+.

Ooops. I just saw "custom chip". Depending on the reprogramming of that sucker (DME?), the sky's the limit!

Well your list is impressive but not all of thos things make power.
Tial wastegate and dump-valve don't make any power. Parallel fuel pumps are probably overkill, one 930 pump is probably enough. How much boost are you going to use? What's the static compression? Are you using stock Motoronic ECU? If everything works and you boost around 0.9 bar you should make around 400hp at the wheels. Cheers!

Having dynoed a few similar engines, I may have a good idea.
whats the static compression ratio How much boost are you running? whats type of intake? ( is it a 3.2 adapted for turbo?) what are the dimensions of the intercooler? Im guessing its a motronic EFI with a chip?

The car has Motronic Fuel system is a 88. 3.2 Boost will be set to maximun of 1.25/1.4 on racing Gas
Compression is 7.5.1 Intercooler Full Bay will flow 900 Cfm |

1.4 bar? MY God Man! You are lighting this torch at both ends.
I pedict 500+HP and a lifespan of less than one year.

Good Prediction Rarly L8 ,
but remenber that I had the car for 4 years and had put 10,000 miles on her, I don't get to drive her that much, In August 11&12 they have the imports and we are trying to finish just before that I had to put 500 miles on her before my tunner gives me the green flag to go, maybe I have to drive her up and down I-95 a few times

I'll put in my guess at 360rwhp on pump gas, 400rwhp on race gas...

Hmm...your list doesn't mention dual-plugs anywhere. I don't want to rain on your parade, but those heads aren't so ping-resistant.
1.4 bar boost + single sparkplug = big holes in pistons, sooner than you think! You can always retard ignition until it stops pinging but then you'll loose power instead.

I welcome all opinions and comments but I have done A LOT OF RESEARCH on this and just like they told me in my Turbo Part 1 that it was impossible to turbo with stock internals well we did this time we will go for and time will tell,I recently meet a guy that is running 28PSI of boost,in a 911,I really belive that for some reason the Porsche Population is VERY concervative when it come to HP in A Porsche maybe because evrything is so expensive,but is only a engine.

Well you are running same C/R ratio as 930, and it's well known fact that 930's don't like more than 1.1 bar boost without O-ringing. Dual-plug helps a lot when it comes to knock-resistance, as single spark-plug in 911-heads is located off-center, so flame-front is traversing longer.
I also did a lot of Saab tuning, where we laborated with high boost pressures vs. well-sorted out ignition and porting. And that was 4-valve DOHC design with adaptive knock-control. At some point, more boost just means more heat and more ignition retard (or more holes in pistons), so be careful with boost-increase. I'm just pointing out what might cause problems. Anyway, i'm looking forward to see the results and hopefully learn something from your expiriences. Good luck!

Beep Beep Don't get me wrong! I WELCOME all the advice I LUV you guys! and luv this board, As you can see I have COATED the Piston Tops,Piston Sides and Rod Bearings in anticipation of this HEAT, I saw this components from another car after 3,000 miles of RACING them and I could not belive it they were like new,the 1.4 bar we planning on RACING FUEL ONLY,the last thing we want is BOOM! but we will push the envelope thats for sure
I know theres a lot of interest in this proyects Rarly L8,Nat Champ, Jacks 3.6 etc so IM SURE that some people benefit from some of us that push it just a bit further.

480 RWHP @ .8 bar
520 @1.0 bar 540 @1.2 bar 560 @ 1.4 bar I believe your at the limits of your injectors though.. you may need to get some 80 lb injectors or something to make more power ( Ford Motorsport seems to be the most economical) you have to buy eight, but you have two spares If im close id rather have beer and salsa LOL

G'Day Juan,
At 1.25+ bar, I don't think your cyl->head will seal too well. You really need to flame-ring the heads & liners at those boost levels. Anyway, at 7.5:1 C/R and 1.25bar, my guesstimate is approx 550 flywheel HP and that's providing your turbo will flow that much. It's also dependant on your Intercooler's efficiency at that boost level. So, I reckon it will fall somewhere between 500-550. IMO, a T60-1 should be a nice turbo for that setup  Keep us posted on progress and actual numbers
