List your PTW clearances

[renogsx]

List your piston to wall clearances, what brand of piston ,fuel ,and power level ,and engine.

I'm running .005 on manley with pump and e 85 hoping for 700awhp at 35 to 40psi on a 2.4 7 bolt.

 

[e85_4g63]

4g63 6 bolt, Wiseco, pump gas, .035 PTW, power level TBA..

I copied this from another thread.

This is for CP pistons

 

[renogsx]

[Sirnixalot]

Wiseco 1400 HD's at 0.035"
sub 450whp power level

What about it?

 

[turboglenn]

'bout a quarter inch

 

[renogsx]

'bout a quarter inch :d

........rofl

 

[ed1380]

Wiseco .020 strokers. .035" ptw.

 

[BogusSVO]

What about it?

there is the image of the factory supplied data sheet.

 

[renogsx]

Ya but what are you running?

 

[BogusSVO]

Ya but what are you running?

It is on the spec sheet.

But if I pulled my engine apart... I would not be shocked to find about .006-.008 PTW clearace after 320K miles No tune, not even a wideband, and boosting 20 on a T3 garrett

I'm running .005 on manley

Should we assume everyone is measuring in inches, and that you in particular are using 4032 alloy pistons?

I would like to see the factory spec sheet posted for all the diffrent pistons used.

That way if a person bout a set of used or open box pistons the info would be here for easy refrance.

you would probably be right . 320k is very impressive is that on the T bird?

Im running 2618 pistons with 9310 pins.

yes it is, she rattles in normal driving, hammer on her a bit, she quites up untill she cools down.

 

[renogsx]

Im assuming its a 2300? I like those motors I can remember reading hot rod when I was in high school the quickest 4 cylinder on the power tour was a guy with a 2300 mustang running 9s or 10s.

I'm trying to open road race, hill climb, road race, street, and drag my car so I'm going to run everything loose to be safe.

CP custom 60 over slugs PTW .0040

 

[VTEC_THIS]

.0045" PTW clearance with Wiseco 1400HD .040 over 8.5:1 stroker pistons. 93 octane fuel (no meth, no E85), 2.3L.

On the spec sheet Wiseco recommends a .0035" minimum PTW clearance with these pistons. I went with a .0045" PTW clearance since Dwayne at Wiseco recommended going with .0040" if you are running 25-30PSI and .0045" if you plan on running 30+PSI.

 

[NHerron]

I have the Wiseco K571M855 (.020 over or 85.5MM) 8.8:1 compression stroker pistons @ .0035" PTW. The ring end gaps are .020" on top and .025" on bottom.

I'm hoping for around 375HP on my Evo3 16G / 91octance + meth cooling by next summer - 6 bolt stroker

 

[caged]

Cp's 9.0:1 4tho clearance top ring 23tho bottom ring 27tho and going for 550whp.

 

[Bo0sTdTsI]

.040 over 10:1 Wisecos. PTW .035 on 91octane.

 

[VETDRMS]

Wiseco 2.4 9.8:1 HD 1400: 0.0045" PTW, ~450auto awhp @ 25psi, going 28-29psi until S256 is tapped then going to S259 billet or bat...

 

[eclipse94turbo]

Im going with a .004 ptw, With a .020 top/.023 second ring. Shooting for 500 hp

 

[dsm's can fly]

.006 weisco HD custom slugs.
E-85 Fuel
made 720HP @ 27 PSI
2.4 6-bolt stroker
8200 rpm

rings gaped to card specs per card (dont forget to add your PTW clearance in the calculation

motor is apart now (rod failure) bores look almost perfect. very little side loading piston skirts still look almost new.
