alright, i have the greddy kit. It was set stock at 5psi. As of yesterday I bumped it up to 8psi. I have a bbk 255lph fuel pump and using the vafc to street tune it. One, i wanted to know if you guys think this is to much boost to run on stock internals and two does anybody have a chart or anything of where i should add fuel to different rpm ranges. I plan on getting rc 310's, but for right now i just want to make sure she can handle the 8psi. Thanks

I'm running 8.5psi on all stock internals, if that helps any. I do however have a lower CR...@8.6-8.7:1

you are running 8psi with a vafc and your stock injectors?

 

that's my problem, i haven't lowered it at all. I haven't heard any pinging or detonation so i think i'll be safe. I don't plan on taking it up to 8psi unless i go to the track. I try to be nice to her on the street but every now and then i have to open her up.

 

yep, i'm also using a bbk255lph fuel pump and she's just street tuned. I'm gonna get the rc 310's and a fpr, but for now i just have her running alittle rich.

 

Audible detonation is very destructive, but why do you think many people blow up their rings/lands/melt pistons, etc? Maybe its because they never "heard" detonation. You should be doing more than just listening. Check you plugs, watch your EGT (oh I hope you have one!), pay attention to the way the car pulls, smells, feels, etc. On stock injectors you better watch yer ***!

 

well let me ask you then. It's obvious i'm new to the FI area, probably cause i worry so much about blowing things. The car pulls nice and hard, it never has given me a problem since the turbo went on. By smells, what do you mean, what would it smell like if it were rich or lean. And to answer you one question, i don't, it was supposed to be installed today, but greddy didn't ship out till wed. and i should have it this coming wed. I don't plan on pushing into boost or past 5psi on the street. But i'm going to the track tonight and i just want to make sure she is safe. I don't drive her hard, but 8psi is 8psi.

 

I have never heard detonation....what does it sound like?

 

smells: burned oil or oil that is cooked off. i think some one posted that honda uses their injectors at a high duty cycle, like 70%+- that would mean they stay open 70% of the time (i think it is crank rotation?) so with the amount of air you are pushing at 5 psi, i would imagine your injectors are at about 100% duty cycle. i would not boost any more with out larger injectors. i would go on ebay right now and buy some dsm injectors.

 

well i have what i believe to be a set of 450's but they look like ****. The black housing around the tip are broken on some and just cracked on the others. I wanted to send them out to get cleaned and everything. But i was told they were alittle to big and that i would have to lean out fuel alot so i got a little hesitate about putting them in. Do you think 310's would be big enough. And thanks for all you help.

 

Hehe, same here

We can compare times Ok, not really...I'll be in a lighter CRX with a manual tranny

 

i personally dont have my 450's yet, but everyone that is doing the vafc hack that i know of is atleast running 450's or 440's. if they can do it i dont see why you cant.

 

*raises hand*

 

your going to mir tonight? tight, what color is your crx? I'll have a red coupe with the turbo. Stop by and say what's up.

 

Oops, my bad. I'm actually heading up to Cecil. It's closer to where I live. Of course MIR is closer to where I work (Bethesda).

Here's a bunch of pictures of my car if we ever do run into each other...
