It's an eagle 94mm crank, 150mm rods (stock rod length), custom spec'd
weisco pistons (similar to the 2.3 stroker pistons but with the wrist
pin moved down 3mm for a compression height of 31.7mm. pistons
were built for 9:1 it also has the ams race balance shaft Eliminator Kit.
tomei 280 cams ams cnc head

rev limit 9,000 done

hurry up and get home so you can get this thing running

 

come on someone has to have an idea.

 

Well are you taking DD rev limit? racing Rev limit? or the rev limit before everything explodes into fine dust?? Safe limit 7800 rpm (i would guess)

 

eagle cranks are known to break, I wouldnt rev it too high.

 

It sounds as though the rod ratio is slightly better than a 2.3 but still worse than a 2.0 so I would give it 8200rpm or so max. If you want to be safe for every day 8k would be conservative enough. If your going for broke and racing it, then 8500 might be an acceptable limit.

 

thanks everyone for the info

 

Since when?

To answer your question the rod stroke ratio is still 1.597 which will be good for low 9k. This combo seems to peak out at 7900 or so anyway with a big turbo (3586 and Magnus) so anymore than that isnt really needed. Look at my build thread in my sig.

thanks john

 

Dyno it, find the peak HP, shift there. Set the rev limit at 8500-9000 RPM. Mine is set at 9k for 4th gear run out at the strip. Thats stock block and head. I shift around 7800-8000 with the Red.

 

Man those are impressive numbers at that elevation11!

 

Thanks
