Have an appointment today at 5 PM.

Mods that matter:

Intercooler, top swap, headers, rockers.

16* timing, 11.3 AFR. KR here and there after repeated 100 MPH pulls.

Full list if you guys really care:

- L36 block 80 something thousand miles.
- L67 top swap with unknown miles on the heads. Never checked for flatness, cracks, or anything else. Probably not good.
- Gen III blower with a mildly ported outlet. I know... Gains are found on the inlet, not outlet.
- L67 TB with a mild port, that magically hasn't affected the MAF table much. Did a bad job most likely. Working on another.
- Gen III WBS 2.25" intercooler. Too tall, blower and fuel rail eat the hood yet I'm stock ride height, no spacers.
- Yella Terra 1.9 RR's with L76 springs/LS1 retainers. Great mod. Didn't feel any difference at all. Drives exactly the same.
- Speed daddy headers with a 3" non-high flow cat welded in.
- Magnaflow catback. Its poopy alright.
- Short ram intake with a very oversized air filter. Driver foglight has ducting running into the engine bay right beside the air filter.
- 3.4 ZZP MPS

For those who REALLY care: 180 t-stat, TR6 spark plugs side gapped at 0.045".

How many horsepowers?

273 FWHP!! When I put in my modded 1.9's I didn't notice a difference either but it killed my 2-3* of kr I had.
 
Re: Dyno guessing time.

What was the highest bid Bob? 281.

Alright, 282 Bob.

(For those who are slow it's a Price is Right joke.)

Thanksgiving here was in October.

Can't wait for it to chuck a rod.

Re: Dyno guessing time.

Underwhelming response, underwhelming numbers.

266 WHP at 5800 rpm indicated on the tach as per dyno tech.

Couldn't get the ignition pickup to work.

AFR was 12.5 down to 12.3 by the top of the gear.

Asked the tech, they change their sensor once a month.

So much for this super accurate AEM WB.... :D

It showed 11.4 the entire time.

Based on my logs, 76 mph is 5500 so theres more in it.

If these AFR's are accurate, NO WONDER I KNOCK.

Are you logging your wb afr or actually looking at the gauge? Cause if your logging it may be the formula your using. I have yet to find a formula for my lc-1 thats anywhere close...
