I suspect Mr. Green's is running rather lean (found the sweet spot at around 15:1 AFR at WOT).

BTW, the stock injectors are specifiaed to flow between 290 and 330cc's, not 380. I see one more person say they're 380+ and I'm gonna kill someone.
injectors are the light green top 315 i belive
i been meaning to change that for a while now
afr are around 13.5 its a little on the lean side
my best 1/4 mile was 15.4 at 87 but that was 2years ago
i'm going again this weekend!!

Just get some 245's for the back and launch it @ 4K

I had an N/A and i beat a lighting (95-) buy two or three cars with 245's in the back.. without em you're stuck @ 15 flat at best stock.

Also.. i really don't think a new coil for a n/a is needed, you get that when you're pushing 250+ hp to make any difference. The only thing the car needs is to loosen the flap in the air meter and a replacement K/N air filter as the stock system IS cold air intake. And headers wont do much ether... just get the 2.5 or 2.75 inch exhaust for it. Any more then that you should just save for a 7M-GTE or high compression pistons to get up to about 250hp and with the headers.

I say that because i was thinking about ordering some custom headers from Magnaflow and the guy when i called told me he has hear of it done and on a stock n/a with a 2.5 inch exhaust it makes a small difference and it was not worth it unless i increase head flow.

The only other this i would recommend for a stock head and bottom end is NOS! 60 shot if its old 100 shot if its under 120k miles.

Port and polish will help, if you don't mind tearing it back down. I'm assuming this wasn't done as you only said 3 angle valve job.

Nice numbers for an NA, if you were on a dynojet your HP would be closer to 230 ;).

Don't think so. Check previous posts. Numbers are just not adding up for the mods listed. Maybe with NOS.

Higher compression like he said? Doesn't really matter what you think, his dyno sheet proves it.

Maybe you're used to seeing worn out 7M-GE dynos versus a rebuilt, or great running one?

I know all about seeing low dyno numbers. IIRC last fall I seen an NA put down about 140ish in Louisville... Who was that person? From what I remember he likes to smoke a lil here and there ;)

Higher compression along with a lot of other things. I have 10.5 to 1 compression with a lot more mods and on a rebuilt motor. Couldn't get those nos.
He must have more mods(a lot more) than he has listed. Or a shot of NOS or dyno operator error. Read the post at the bottom of this page about dynos.
I think the guy in Louisville was Fuzz and he stated the picticulars of his dyno run. Check the posts, he had his dyno sheet posted and I had mine posted. Like I said I had mine tuned with a Apexi II and Green dosen't list any tuning tool but FP. The Dyno sheet is there to prove it. 150-160 rwhp for a stock GE is the norm. Show me another dyno sheet with just those mods or close to it with 200 hp just dosen't add up.
He said he's running 13.5 AFR same as mine which is on my dyno sht.

I just don't see what he could gain by being untruthful, usually people want to brag about what they have done to their car.

Not saying he's being untruthful, just saying it's not adding up that's all. Even running extra lean would not make that much difference. And if he's running that lean he won't be running very long.:3d_frown:

Doesn't make a difference what mods he has. He has proven with a dyno sheet what he has, big deal, 200 is 200 no matter how you get there.

And yes, it was fuzz, I already knew it, I was teasing him ;).

Hi guys thanks for the input
The dyno I was using is a very reputable dyno http://www.wallsrodcustom.com/ in the city, however after talking to some of the guys that had their cars dynod there, they said it might be reading too high.
So the plan is to see what kind of 1/4 mile time I get and if I have enoughf money I will dyno it again at http://www.motionperformance.net/html/dyno.html
they have a SuperFlow 845

best 60ft i got was 2.08 i think
i didn't port/polish anything btw

ROFL!!!! Have you even seen AJ's build specs? Oh god, you're killing me!

The originator of this thread is running lower compression than I am! He's got an aftermarket coil, he's running lean as hell, he's apparently using using high impedance injectors with the coil pack for the low impedance injectors still installed (from what I can tell from all his pics anyway).... The only way this guy is making 205RWHP is becuse he's driving on nothing but detonation (which is a great power maker if timed right.... for about a day.) or someone at the dyno didn't want to disappoint him and "tweaked" the initial settings. That or he's done SHIT LOADS more work than he's telling anyone.

What's your point? He got what he got, stop whining about not believing him when he says he has such-and-such mods in his car. Like I said earlier, do what you've got to do to get what power you want.
