Well I went to dyno my baby today...2001 Type R #220 with 75k miles.....
my mods are:
Type One Racing Testpipe
Type One Racing exhaust
J' Racing Intake
DC JDM 4-1 Header
VAFC
Kenji chipped P28

The numbers were a little low IMO 165 WHP was my best run i was expecting at least 170WHP...

But the strange part if you look at the graph after 3 runs on the dyno i starting losing tons of HP on one of my runs when vtec hit i was only hitting 139WHP which is very odd...the place said my car might be runing a little too hot...but the temp was little above normal...im guessing it was the dynos error...considering my car sounded fine and the air/fuel curves are very good. any feeback is welcome.

 

ouch

 

i just dont understand how i could go from 165whp... and three pulls later only adjusting the vafc barly i goto a 145whp??? anyone got any ideas?

 

Any CEL? How does the car run now?

 

No CEL and car runs fine

 

With similar mods I was making above 170 on a dynojet at about 75 degree temps.

 

for lazy folks...i broke the dyno down a bit the first run i peaked at 165whp at about 7800 rpms...2nd run peaked at 164whp at about 7600rpms...3rd run peaked at 161whp at 7400rpms... after 7400rpms on the 3rd run there is a big dip in WHP (the green line) then to the 4th run i peak at 148whp at about 6400rpms and then HP starts fallin which i have no clue why because we did not touch air/fuel since the 2nd run...after the first 4 runs it is all downhill...lowest peak was run 7 at 137whp which breaks my heart...i immediatly start to think maybe my motor is going...but it sounds so strong the whole way so i dont know what to think...oil was fine...we decide to let the motor sit for 20mins to 30mins and then let her rip for an 8th run... now during the 8th run i make the best midrange power hitting 150 whp at around 6400rpms... so maybe this will give me a good run but no HP starts to fall all the way down to 140whp at about 7300rpms and stayed there till 8grand...i dont know what to think of everything...my air/fuel curves look fine to me any comments?

 

temperature was around mid 50's and raining

 

man, that's not very much.

 

im guessing this has not happend to anyone else?

 

I've had a drastic drop in power after several consecutive runs before too...you have to let the air inside the engine bay cool down for a while first...the drop in power is nothing to worry about in road conditions because your car will be moving and cool air would be going into the engine.

 

aight cool thanx alot man

 

Are you 100% postive about the ecu?...what about your spark plugs and timming?..well not really timming but lets say spark..thats is very odd, check the compression.

Don't mean to bring you down but, those are low numbers for you mods..I hit 171 whp with just aem cai.

 

im not really worried about the 165 being a little low...i realize its a little low...im gonna go back in a few weeks and well see the results...im not too worried because im pulling on 200whp rsx-s the other night

 

traction not good maybe?

 

traction for who?

I think he means on the dyno?

 

Double-check everything .. I was pulling 164whp when my R was totally stock. After checking everything out I found out that I had a blown head gasket ..

 

Dude, you should be making way more than 165 with those mods...something's up.

 

thats what im firguring im gonna check the car out today

dyno is Pampena Motorsports...only AWD on Long island and NY
