<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by StolenTeg &raquo;</TD></TR><TR><TD CLASS="quote">less than 320whp</TD></TR></TABLE>

is there a chart somewhere?

 

they could probably handle around 400 whp.

 

i would also guess 400ish

 

370 ish, probabaly ~85% duty cycle

 

general rule is 1hp per 5cc

so each 550 COULD handle 110hp which makes 440hp.....but that is just a rough number

here's a rough guide

310cc 200~220whp
370cc 220~280whp
440cc 280~330whp
550cc 330whp~380whp
660cc 380whp~425whp
720cc 425whp~475whp
880cc 475whp~525whp
980cc 525whp~600whp

 

You can make close to 400 depending on duty cycle and fuel pressure I would not recommend it but it can be done. A good safe range for those is going to be more like 320-350

 

only going for 300ish on a stock gsr block

 

I saw in a magazine one of the Cibernations cars in Miami make like 550+ hp with 310cc injectors and their black box. It was running a weird setup, I belive it also had an fmu. The Type R ran 10's consistently. It was pretty sick. Not saying I would do it but just giving an example. I also have 550 cc for my stock block gsr tryingto get like 330hp.

 

what about 440s my friend is going to use them and he should be making about 275 whp

 

i was run n about 90% duty cycle on rc 550 ccs in a prelude making 335whp

 

go bigger so you dont have to upgrade down the road.
