cutlass · 07-30-2003, 08:02 AM

I need help! I'm looking at a HKS stage 2 cams for my H22A in my Prelude but I know nothing about HKS cams are they any good has anyone own a pair run them?Help Please.

dvs_prelude · 07-30-2003, 08:39 AM

I don't even think HKS makes cams for a prelude or any honda engine... Don't they make parts for turbo cars?
BTW, you should probably start your own thread regarding this subject.

178.5 hp and 141.8 tq

This was from January, before Honda had to replace my motor under warranty (even with my mods listed!) b/c of a spun rod bearing. Same mods except i fixed the "missing" parts in the graph, which were due to old spark plugs (honda dealership didnt change them at 60k service) that were way white b/c of the VAFC settings i was using from NTPOG for over a year. Also replaced the spark plug wires which also could have caused the gaps.

Mods at time of dyno:
AEM CAI
DC Header and Exhaust (got rid of the DTM "dirty" tips though)
Testpipe
ODB-2 Workaround Mod
Aem pullies
VAFC (baseline in graph was with settings from internet NTPOG i think, and the other is after tuning)
My 4th run was the best in terms of power, as it hit 181. something, but the final number dropped a little as i leaned out the final setting all the way the VAFC could go, and as you can see from the fuel/air ratio, it still wasnt enough!

BTW for all you doubters, my X over point is 4500 and as you can see i gained almost 10hp at the cross over from the other 4700 rpm point.

I GUESS thats it! Have a good one!

If you want full size of mine above add ".orig.jpg" to the end of the file name in a web browser window.

THEDREAD · 10-20-2003, 10:10 AM

Mav, what cams are you using and how much did it cost for your bottom end.

Mav97SH · 10-20-2003, 12:39 PM

thedread:

The head is stock apart from whatever is listed...

Bottom end? well the only real upgrade in the bototm end was the pistons which ran me around $250 USD w/o rings. I dont remember the xact $ value of how much the machining was....i do remember that all the machining (milling, valve job, hone/bore) all came to around $500 CDN.

These runs were actually made a few months back.....a lot of people were shocked to see the amount of power put down...as a baseline even. stock cams, no tuning. It was begging for some high lift cams.

Since then i've had to sell the car+motor with it, it was a H22A4 in a 97 SH. Now im looking to build a H22A1 similiarly, but with some cams this time and standalone ecu. I should have results by next summer

THEDREAD · 10-20-2003, 06:16 PM

Cool. Talk about hp on a budget. I'm in the process of sprucing up my 4th Gen. So far, I done bolt ons and suspension. Next is the engine and then body. I'm looking at probably going your route, but with headwork and Jun cams and valve springs. Hopefully, I can touch the 200 barrier

Mav97SH · 10-21-2003, 07:08 AM

actually...that setup alone ran me about $6000 CDN.

1800 of that was labor, the rest was R&R/aftermarket (i.e pistons, clutch etc.)

THEDREAD · 10-21-2003, 11:16 AM

Still not bad......especially considering the CDN $

Last run meaning run number 3 with 146 hp and 148.9 TQ?

prelude2sin · 01-31-2004, 07:57 PM

si4ws- yeah. i think the flapper was not opening completely in the 1st and 2nd run.

One Slow Lude · 02-09-2004, 09:02 PM

the car is:
97 sh

the mods were:
AEM CAI
DC SS Header
Tanabe Racing medalion exhaust
VAFC-tuned (supposedly even though i only gained 1 whp)
yeah i think that is it in the way of performance....

im not happy at all with the number, seems kinda low to me, but oh well.....

The later Dyno had a tq spike, adjusted based on graph. When I get the raw data, i'll post it up.
