HP Junkies Turbo my 3. 2 to 3.3 Up Date

[juan ruiz]

Ok just to get the Junkies a Fix.
The engine is all apart and were eager to put it together i have a DATE when done with a 3.3 Turbo with similar up grades like mine not the cams or Motronic all eyes picking my car as a winner because of the CSI on the 930 but Will see.. this is how far were are;
Heads are ready,both heads and cylinder are now with a
Nirosist Ring
Intercooler is on the way
Clutch is on the way
Pistons and Rod Bearings are been coated with Zirconium Gold Coat
Raceware Hardware we have
Evo GT 2 Cams been done
The rest is misc Fuel Pumps,Injectors etc,etc the easy staff
The next post will be on FIRST Driving Impression so until them.
HP=

Looks like it's coming along.

As we all know the 3.3t CIS will support up to 450hp. What are your projected numbers? The 930 is probably a heavier car. Tranny is different. It should be a good race.

The proyected numbers in PAPER look very good but it be difficult to guess but if I went from 217hp to 320 hp with the turbo When I was told I should be at 340-360 hp with headers which I never Had so thats - 40hp or so,so with ALL the research done Again on PAPER and cars with similar set up we are looking at
485Hp @ .85 to 1.0 Bar of boost TO 545Hp @1.25 to 1.4,So with 500Hp We be happy but only the Dyno will be the judge.

On the 930 thing even if he is heavier, different gear box, etc
I just want for my own to really see if the 3.2 is better to Modify than a 3.3 again just for my own but if i lose is not big deal im more concern for the other guys but then again WE WILL Run NOS for sure so we are really preparing ourselves(SO WE THINK) I let you know

My God man! 1.4 bar? Are you nuts?

As for the 3.3 vs 3.2 build, I can't really see where either has an advantage. To do what you are doing would require changing cams, P/C, fuel management, etc on BOTH engines. If you're going for 500hp with a 5 spd tranny you shouldn't have any trouble beating up on a modified CIS 930. I think it is obvious that you will have a less reliable setup, but I know this is of no concern.
What are you doing for your tranny? Will the G50 take dragracing abuse?

I want video and photos Smokem!

Rarly L8,
Yes we will start with the G50 Tranny or may have to move to a G50-50 or some other solution,I haven't even start on the reasearch for the tranny any ideas? Anyone?
Maybe some of the other HP Junkies here can help me with this issue,??More concern at this time is that we feel the need for Positraction thats not big deal,neither the axles I have found a source for them. Will see do,Today im going to the Camp so i will ask the boys .

You'd be surprised! Even the 3.2 with an Intercooler & associated plumbing etc, WILL weigh about the same as a 930. My 3.2's rear has just put on an extra 40-50kg's in turbo plumbing and as a result, the rear is squating down much more than the front, so we now have to lower the front and possible raise the rear to balance it all out. I can't lower the front too much because I'm running 18" rims, so there amy be some guard issues. I may have to lower front by 5mm, and raise the back slightly to level out the car.

Anyway, Juan's car will be a blast. 1.4 bar on RACING gas is OK. Wouldn't work on street pump gas. 1.25 MAX on pump gas, and even then, you need the high quality stuff (93CLC) or 98 Octane and EXCEPTIONAL intercooling, BIGGER injectors & higher flow fuel pump(s).

It'll be a last Juan! Keep us posted!

I hate to sound like the voice of reason here, since I'm rarely reasonable in this area, but there is NO WAY on God's Green Earth I would run 1.25 bar on 93 octane pump gas for any length of time more than an eyeblink! Not unless the dough for a rebuild didn't mean anything to me.

However, with the right gas and engine (with the Niresist rings, the right rods and bolts, etc.) I would and have run MORE than 1.4 bar for short periods.

Of course, because of a programming error, I once ran 1.7 bar on 110 octane gas for 30 minutes. An astonishing experience. Chunked a piston, though.

My tires literally melted onto my flares in streaks. I figure I was somewhere over 600hp to the wheels.

GAWD that had to be a fun ride!
And a nice handfull of these probably drifted away in the cloud of smoke.

[Bruce M.]

You are correct, sir.

Nice picture. Never seen one of those in real life.

[WydRyd]

I would have to agree Bruce. Over 1.1bar on Pump gas is just BEGGING for a mechanic to rip you another a.hole in repair bills

I would limit boost to 1.0-1.1 on street gas.

If you have access to race gas, then fine. 1.25 would be safe, however, in certain countries (like Australia), it is illegal to run RaceGas or AvGas in a street vehicle. A fine of up to $125k can be imposed! Aaaarrrggghhhh!!!

That's why people tend to use Octane Boosters to have that little safety margin. I don't think they necessarily BOOST octane by the claimed 7 points or so, but they do help bring octane slightly up on a run of bad fuel. I'd say more like 2 points or so.

There are only 2 or 3 boosters that actually boost octane and even then, NOT by the amount claimed by the vendor. Typically, 2-3 points MAX is the end result. SO, on 98 RON, they usually boost up to approx 100.3 RON.

Having said that, I wouldn't run more boost just because I'm running an Octane Booster. It just gives you a bit more safety margin or peace of mind at the same boost level.

Out of all the tested boosters, Nulon PSO is THE best you can buy. At $20 a bottle (500ml), it aint cheap, BUT it's been lab proven to work. See www.nulon.com.au.

People who import the WRX Sti's from Japan (206kW) version, run this booster in order to match the Japanese 100 Octane requirement for these engines (from a base of 98 Octane). So it does actually BOOST, just not by 7 points on higher grade fuel

So, 1.7 bar eh? That must have been a blast, especially to the wallet

Sorry for the rant...

[WydRyd]

BTW Juan. Did you consider getting your 95mm cylinders bored out to 98mm and recoated in Nikasil?

I'm told this is what Mahle and Ruf do for their 3.4L kits. They are based on a 95mm cylinder and simply bored out and re-coated. The thinner cylinder well is well within acceptable limits I'm told.

EBSRacing or Kevin Roush from GAS Motorsport does this mod and they have not seen any failures in street or race applications.

It might have been a cheaper solution to getting 3.3 P&C's.

You then could have had some 98mm forged pistons made up for your car at whatever C/R you wanted.

Just my 2c worth.

Merv We did consider SO MANY COMBINATIONS thats not even funny so of course the $ is always the problem so I stuck to my game plan, after the DTA Electronics,on the future Headers,Make her twin turbo do the interior, I will be done with her and just drive her,but i will go to the next proyect which im currently doing reasearch but it won't be a P Car, My eyes are on a AUDI,I hear Supras are comming back, or some of that nature (I saw a 1,200 hp street supra) oh boy! some that you can go to 711 and get parts but will see..
