List your mods if you want, however no comments, and posts without a DYNO chart will be deleted. Also it's better if they are SAE corrected.

Winton : 1:48.2
Sandown : 1:38.3
Here's mine
Red line (105kW) is with air box removed, lower line (97kW) is stock. H23A 1993. Since then I've done I/H/E so I'm hoping to get it dyno'd again soon
Update:
Just got redyno'd at 103.8 killer wasps. I'm pretty happy with that, a lot of people on the day mentioned that this dyno is a bit more conservative, so perhaps 10-15kW gain from my mods![]()
Engine Mods
Engine KMS - 300,000+kms, since Rebuild approx 20,000kms
Simota air intake with K&N filter
Cat back exhaust with varex muffler
First Run varex closed
Second run varex open
Same engine mods, but have VAFC installed
not sure what happend with the first run - maybe it was not reset.
both runs done with exhaust open

Well, nobody seems to have a chart up....?
It's my first EVER dyno run.
No real mods to the engine. Just an intake and exhaust.

Link to my garage.^^^^
When words fail, VTec speaks!
This is my first run from 2008
1993 JDM H22 Bluetop
Mods included:
K&N Podfilter
DC Headers with 2.5 Inch Exhaust System (with mandrel bends)
Skunk2 Cam Gears
Have not been on a dyno for a while now so no idea what its making today, probably alot less
Power Hammond, Is everything - Jeremy Clarkson
Two plots I can contribute from my 1991 BB1 H22A with ~240k kms (note- automatic gearbox):
First plot:
94.6wkw---Blue line mods (was running way too lean...)
Mods:
CAI- Simota filter
Vision ignition leads
Iridium plugs
PowerPro Euro muffler
Gizzmo CAMFC
111.6wkw---Red line mods= same as blue but with:
D1Spec FPR (no vac fuel press = 44psi)
CAT knocked out
Replaced LMAs with spring type
Modified IAB valves to open at 3.5k rpm
SAFCII- bum tuned by me
AEM UEGO wideband
Second plot
127wkw---Red line mods- same as red line in plot 1 above but with:
Hytech-replica header (also scraped out the carbon build-up from the exhaust ports)
Full 2.5' exhaust (still PowerPro muffler)
Ignition advance reset to stock, fuel pressure increased marginally, removing ~10-24 SAFCII units and using 98 Octane. Datalogged the AEM and did many second gear pulls for tuning, but stock p13 maps are crap.lol.

Been a while, some more dyno plots to throw up for reference. Different prelude to the one above- 1992 BB4 manual with 272k kms.
In 100% stock trim (252k kms):
Power when stock (New Iridium plugs = only change):
159whp @ 6800rpm with ~ 600wnm @ 5400rpm
Current power:
194whp @ 7000rpm with ~ 680wnm @ 5000-6500rpm (note- there was a dyno inbetween stock and the current- IHE + Crome tune only)
Hence, a net gain of 26wkw/35whp following (done on the same dyno, 1.5 years apart):
Custom CAI with Blox velocity stack and filter
70mm Skunk2 T/B- port matched 70mm tapering to 65mm.
Mildly ported P13 intake manifold with two IAB plates- one functional and one without IAB valves and Blox phenolic gasket.
Rosko EGR blockoff plate + EGR delete
Vision ignition leads
D1 Spec FPR (fuel pressure ~53psi no vacuum)
Hytech replica header (no collector mod)
Custom 2.5" exhaust (no cat, 1 resonator, mandrel but in sections welded together)
Exedy OEM clutch (no gain expected)
Aircon delete
SAFCII, AEM UEGO and Crome tuned P72 (Vtec at 4700, unsure of IAB engagement rpm; further tuned using wideband, SAFCII and FPR as extra mods were made).
And 16" BBS RG rims (fitted with no name tyres.lol).
Still more in it, should break 200whp with just boltons without too much trouble.
