Just wondering how much everyone is spinning their all motor engines??
and what kinds of mods are done!

Thanks

 

Check the dyno thread up top.

 

^ has a good point, but for what its worth i ran my 100% (internally) stock jdm h22 to 8200 for 3 years without issues.

 

h2b 8300 no problems

 

Spun my h2b to 8100 with no issues but i also didnt beat on it a bunch

 

8200 rev limiter h2b

 

always 8700....hit 9500(built motor) on the dyno a few times but it does not make the power i want up top

 

~8300 in racing situations. I just took some measurements with a bore gauge to check for roundness and i just bought a couple micrometers so i can buy some new bearings but when i get some more info, i will post up about it. This certain block saw 8300 quite a few times and the wear patterns on the bearings sure dont show it taking any abuse.

 

And for the h2b peeps, who are running a b16 tranny... on the strip are you guys comming out of 4th gear at the end??

i will have 23x8x13 slicks and i don't know if i'll be ok!! i really don't want to shove it in 5th gear at the track!!

 

Im using a J1 trans. Check out mfactory's web site. They have gear calculators on there.

 

does anyone have stage 2 cams or better and using stock valvetrain by any chance and if so how high much did u spend it.

 

9700 . . . ..

Oh wait that was a mis shift . . . oops . .

8100 on a stock h22
9100 on a 90x102 build. . .

Although most H series builds I see dont make power much past 8500 anyways

 

8500 rpms with the 95mm crank.
same with the new 97mm engine thats going in
racing shift points.
.............
on a daily drive i dont rev past 8000.

 

here are my main bore roundness measurements from the h22a

Main1
0/180* = -.0303"
45/225* = -.0287"
90/270* = -.0276
135/315* = .0291"

Main2
0/180 = -.0298"
45/225 = -.0292"
90/270 = -.0285"
135/315 = -.0294

Main3
0/180 = -.0300"
45/225 = .0291"
90/270 = -.0286"
135/315 = -.0298"

Main4
0/180 = -.0301"
45/225 = -.0291
90/270 = -.0286"
135/315 = -.0299"

Main5
0/180 = -.0300"
45/225 = -.0288"
90/270 = -.0281"
135/315 = -.0294"

I'll do the rod roundness when i get a chance. I bought a couple mics the other day and im waiting for them to come in so i can measure everything for bearings. Back-up blocks ftw

 

what type of arp bolts are u guys using for the h22/f22 crank and rods. B/c i got some arp gsr rod bolts and they cam up short. I only had 4 threads for the lock nut.

 

9000+ on my f20b i feel like it belongs in the h22 conversation.

 

i take my f20b to 8500, type s cams, stock block.

 

Since 2003, (same stock jdm, shaved head, motor I have had in 3 street/strip cars) The limiter has been set @ 8175, I shift one nut hair before the soft limiter hits. But she only makes power til 7700 and some change.

This season I'll be testing out a few 8300 (with like a 8310 rev limit) shifts as I think I can get ~ .30 knocked off my 1/4 with a later shift.

 

stock internal h2b w/ b16 trans-8700rpm all day at the track, crossing traps in 4th around 8500rpm

 

so no one is using upgraded rod bolts to spend these things

 

no you do not need to upgrade your rod bolts.

 

I'm doing 8500 rpm. No need for rod bolts like NAH2B said....I do believe that the H is stronger than we give it credit for.

 

sorry should have said before i mean i'm talking about with f22 crank/rods u guys are still running f22 stock rod bolts and all turning 8000+ rpm.

 

so your trapping 8500 on the strip in 4th?? is that with b16 tranny and 22x8x13 slicks?

 

i was crossing the traps @ 8000 in 4th gear with a CTR trans w/ 4.7fd
