wanted 155mm rifle drilled rods

[Jamo]

On topic pauter can do these s mine are 155mm rifle drilled

[Pat D]

Mine is built with 155 allows for better compression height on the piston

Americans tend to use 159mm strokers
Scandanavians tend to use 155mm strokers

What do you mean by better compression height?

Wouldn't this require more material in the crown and therefore a heavier piston?

[URQguy]

Yeah, what is better about it? We have built a few tall deck 95.5 with 160x20 rods and 29.0mm compression heights, and they have never had ringland failures. I recently windowed a tall deck with a Scat 159x20mm rod failure, but never have I had pistons problems with 29mm compression heights on our 160 rods.

Urq guy, are your rods rifle drilled? What's your thoughts on this? Price?

[diesel des]

Jamo, any contacts for the rods your useing. Did they come direct or through which dealer. I have a feeling they arnt cheep. I can get non drilled 155 rods and good pistons for 850 quid. Very tempted.

Chill
Pays your money take your choice 155mm means you have the same ch as oem pistons
As said there ate two ways of building and mine is done the way of the scandis

They were direct from pauter
No not cheap but rods aren't something you scrimp on

[Pat D]

I don't see the point in saying thats how others build an engine without shedding some supportive info. Why not use rods shorter than 155mm and pistons to suit if they are cheap enough.

I agree with Error404 and JP's advice with the rifle drilling for longevity, and I have gone the same way with mine. As for rod length, you will have less piston side force during the stroke with longer rods which would mean less scuffing and wear on piston rings. If I was to build another stroker, I will choose to go with 160mm rods and 9A pistons, which if I remember correctly have a compression height of 29.5mm. Perfect setup for a stroker IMO.

[Jamo]

Well the point is any stroker is a custom build there is no supportive information for not building it this way or the other
But as typical when people who have gone the 159mm route swear its the best way because of rod ratio when I checked the difference in rod ratio between the two it is not even worth mentioning
155mm scandis say compression height and free revving is better
Pays your money make your own fricking choice
Don't have a go at diesel des asking where he can get these rods ( it seems I'm the only person to have answered his question btw )

[Jamo]

Didn't Aron have 155mm rods for sale a while back? I don't know if they are rifle drilled though

[Error404]

He was going to make some but there was not enough interest IIRC.

Remember on any build everything is a compromise and there is more than one way to skin a cat

[diesel des]

Arons rods wernt drilled. I'm getting some interesting prices so will let you know. Cheers all for the help

[|CL|NIKI]

I got mine for 28 usd for 1. Chinese can manufactured any size /dimension. They are not drilled too. But are strong enaugh.

[andy10v]

Urq guy, are your rods rifle drilled? What's your thoughts on this? Price?

$695 for 160mm

They feature 20mm wrist pins along with riffle drilling for additional cooling to the pin.

What boost and HP wil 9A pistons hold-they are not forged IMO???
