What boost do you think is needed to run 310-315rwhp?

See my sig for mods.

I will be going to the rollers soon! I think I am around that figure already, I might be wrong.

Guys?


Thanks...

10 lbs. ....12lbs should give you 335 or so and 14 360 rwhp..

 

yeah, 10 lbs you should easily see 310-320 rwhp

 

Guys are you serious? That much! Or is that on the better side?

Also I am fitting a GTR fuel pump, do I need uprated injectors to run 13psi?

Thanks...

BTW, the hp figure in my sig is quoted at the Flywheel!

I was just looking at your sig to check your mods again - please tell me you have some sort of ecu upgrade......if you don't you engine might not last too long with all those mods. 310 rwhp can easily be attained with a dp, mp or hi-flo, catback, intake, and ecu running 11-12 psi. You have a streetport which usually adds 20-30 rwhp depending on the car. I remember a guy dynoed at 321 rwhp with a dp, catback, intake, streetport at 12 psi - no IC or mp - you should be able to see 310 rwhp at 10-11 psi but you need to have some sort of fuel computer or ecu

 

You seriously need to upgrade your ECU.
Don't put your car on the dyno without upgrading your ECU. Also, don't drive the car hard. You should easily hit 310 RWHP @ 10 psi.

 

the first mod listed is PFC. maybe he is talking about the Apex Power FC.

 

YES! I do have a Power FC ECU!(Hence PFC in my sig). It is in my sig as someone spotted. However, I have changed the wording so it is understood better.

Thanks for your input but...Do I need to uprate the secondarys yet, to run 13psi?

Thanks to all...

The fuel computer at RX7.com says the stock fuel system is maxed out at 380 flywheel hp - so that means at 320-335 rwhp your injectors are running at 100% duty cycle - you want them to stay around 75-80% at full boost to be safe. Usually 1300cc secondaries are plenty for most modded FDs unless you are running more than 15 lbs through a single then 1300cc is fine. With you running at 13 psi with all your mods you should have some injectors - not that you couldn't get away with it as many have done - but it would be smart to have some. Put it this way, I've been running 13-14 psi with all of my mods for a year now with no 1300cc injectors - they are in my sig because they are being put in in less than a month.
