I want to ask those who use the crankshaft or f22b h23a1,!
my block
Darton mid sleeve
crankshaft f22b
H-beam arp 2000
CP Pistons 89mm
arp main
who uses such a build? tell me what max rpm you use? How many miles? What work was carried out with the crankshaft? both.
USED ​​car will drag

 

You made no mention of the most important part of running high rpm on an engine. The valve train and bearing clearances!

That stroke with OEM clearances is really built for 7200-8000 on a stock H22 valve train. Again a little more about the top end and your clearances will help. I'm only assuming that you are using an H22 head by your user name.

 

I use the h22 head
OEM valves
sk2 valve train
camshafts sk2 pro1
I want to use Taiho bearings, clearances OEM
draw conclusions from the forums, that the crankshaft does not have in terms of reliability, survivability bearings, I was interested in this moment
What better use bearings, clearances, and what is necessary to work with the crankshaft,for reliable operation in the 8000-8500rpm?

 

If you use stock H22 clearances for the bearings and run your SK2 valve train. That should be able to handle your goal of 8000-8500 rpm easy enough.

 

connecting rod and main bearings with adequate oil cooling are doing well at 8500 rpm? then you do or balancing of the crankshaft is optional?

 

8500 rpm with quality bearings and proper clearances will be fine.

When you are changing out rods, pistons and the crank you should always balance the rotating assembly. Balance it according to the RPM that you plan on having the engine run.

 

plan to get 750-800 whp turbocharged 42R, C16 fuel

 

Well that changes everything..... you probably shouldn't be running OEM clearances with boost and that much Hp from an engine. I would imagine that the pistons and bearings will require more clearance than a stock H22 runs.



And this is now a topic/thread that would be better suited in the forced induction forum, not the all motor forum. You will probably be able to find more information in the FI form.

 

piston-cylinder gap I made in accordance with the recommendations of CP Pistons for drag racing 0.1mm
Do you think that the bearing clearance must be different from the OEM recommendations?

 

That is a question best asked of someone who builds forced induction engines. I have my own thoughts on clearances. However, I have never built a boosted engine so they are just that, thoughts.

Sorry I can't be of any more help. Hopefully someone else will chime in and help out!

Cheers

 

Thank you for answers
p.s. you have a best accord cd5

 

Thank you!
