Darton Sleeves, CP pistons 9:1 and BC H rods. looking for about 600whp

 

So you staying wiseco pistons? What wrist pin are you going with..?

yea i spoke with a really cool at wiseco about what happened and hes gonna build me some custom pistons with some crazy wrist pins, and getting this crazy coating on them, i forget what the coating was called, I may go with their k1 rods too but now sure about that yet

 

Also keep in mind that wiseco and CP use a shorter piston than factory. Stock pistons come out of the hole 0.040. Those do not. If you have them make pistons make sure you take that into consideration when calculating compression height. With a stock size dome lowering the piston 0.040 will lower compression about 2.5-3 points.

At that rate an 11:1 piston will require about a 12ish-cc dome... I'm not a fan of a domed piston under boost. A flat piston works much better.

I'd make it stock compression height (1.181) and flat.. on a 2 liter that will get you right at 10:1.. on a 2.2 a little under 11:1.

Also remember the stock chamber is only 86m. In diameter. Any oversize piston needs a chamfer on it to keep from hitting the head

 

Sounds good. I think I'll probably go with a custom set of Wiseco Pistons(10.0:1), Brian Crower Rods, and Darton Sleeves. Any suggestions on Bearings?? (OEM, ACL, ETC...)

 

Any suggestions on bearings guys?

 

im a fan of the oem bearings with clearances based on whatever hp you are going for. but that is up to the engine builder in my opinion.

 

Use what ever bearing your engine builder likes to use. My engine was built with acl race bearings and my shop warranties the motor not to fail (within limits) so I told them to build the motor with parts so I can make over 900whp.

 

Golden eagle sleeve
89mm CP 9:6.1
BC rods
ACL bearings
ap2 micro polished crank
ARP head studs
OEM HG
Piston to wall clearance 0.42 - reliable 600whp Daily driver/road course engine

 

I don't think .42 ptw would be real reliable.

 

well I am building a Benson block in February so I guess I need to start learning clearances lol looking for 850 hp cp pistons and grp aluminum rods 11.1 comp.
