Most Powerful Naturally Aspirated CB7 List

[GunRunner]

Wonderful, and we have our new king! Do you have the machine shop that did the bore in your MRT? That would be a definitely good resource for those who don't want to sleeve or pay the premium for some of the big names.

InlinePro did the bore, and at a reasonable cost. $350 not counting shipping. For a good quality FRM bore/hone it is worth it.

GunRunner, is that car street driven? I'm really wondering if you have emissions numbers for that piston/cam/header combo...

No emissions in North Carolina, unless the car is OBD2.

Not bad, I knew InlinePro specialized in S2000s so I guess H22s would be right up their alley as well since they are both FRM. if I was closer I'd consider shipping up there. It would probably be right around the same price from Florida. But I guess it doesn't hurt to ask. On your adjustments are you aiming for more torque? I was thinking with 230whp+ wtq would be somewhere around 190-210wtq

Making some intake and exhaust changes. I'm happy with my current numbers, but an increase in any area is never a bad thing.

I'm loving the N/A numbers, I need to find a good DYNO shop see how much I'm pushing to the wheels.

Getting mine tuned on April 18th and I'm aiming for 210whp hopefully haha I will post up the results as soon as I get them.

Made 193whp and 134lb-tq on a Dyno Dynamic....disappointed in the numbers =T cams were being a pain and when we were trying to set it between 4.5k-5.5k it would bog down and die. So it had to be set higher but then another disappointment. Maxed out the fuel pump so it was cutting off at 7.4k...If I get a walbro pump I'll be making 200+whp

Great Job to Sequence at #6, hope you get your TQ numbers worked out.

List updated.

sequence, stock h22a4 make those numbers, check your compression and the health of your motor, 134tq is depressing, and you should be well over the 210s on a healthy block

[GhostAccord]

It's the header!...lol

Maybe the tuner?

[drummersteve7]

did you dial the cams in or just install?
I am going with the cam lift is not hitting exactly when you need it to.
Sounds like timing could be way off, did the tuner play with timing at all.
I could see that H22 wanting to push power but if timing is bad tq is low.

Where did you get it tuned?

lmfao thanks a lot =D hopefully they go up soon!

yea going to be checking out my compression soon i was pretty upset with the results but i was also running on a dyno dynamic which usually read lower. if i was on a dynojet i'm pretty sure i'll be hitting 210-220whp easily.

It's the header!...lol

lol it is, the low end is pretty horrible ahahah

Maybe the tuner?

tuner was good we went over as much possibilities as we could. but who knows maybe i'll take it to a different shop after i upgrade my fuel pump

i got it tuned at a shop in minnesota called DB Performance. the cams were dialed in but maybe i might have to check it again and we played around with the timing but it didn't make much of a difference. when we set the vtec to engage at lower rpm's it would bog down and then shoot right up

[drummersteve7]

how does it act without vtec engaged?
did he try that.

most tuners I know will tune without vtec first which is why I ask.

we didnt try that =T vtec was engaging fine though the power jumps up pretty quickly and it's a noticable pull when it engages.

Is it just me, or is drummersteve7 referring to valve timing, whereas sequence is referring to ignition timing? Just for the sake of sequence. Good luck!
