needs more tuning it seems.

If ur tuner cant feel it and u can, put it on a dyno.

Re: (93supercoupe)
 

what are u tuned on?

definetly in the tuning...

your tuner probably didnt get the fuel tables right for vtec...
IMO, id be lookin for a new tuner.. this guy doesnt know what hes doing...

did you have a wideband in? or on the dyno? what is the A/F like? around 4500-6000

Re: (Topdawgg)
 

it was tunned with crome an yes on wide band. street tuned

Re: (DrivinVtec)
 

so what is the A/F lookin like in those areas?
you must have been in the car when he was tuning

Re: (Topdawgg)
 

maybe he set VTEC too early. but preludes usually like VTEC set really low

it would totally depend on the setup!!

injectors, spool time/turbo size....
its something that has to be played with

Re: (Topdawgg)
 

this was while back. i dont go in vtec very often. idk

get it on the dyno, or get another wideband in it.... its a tuning problem, id bet money on it

its about to get rebuild with a new bottom end. ill just wont hit vtec in it to be safe.

oh..thanks for the help

Re: (DrivinVtec)
 

get it on the dyno, why rip it apart if theres nothing wrong but just needs better tuning?

Re: (Topdawgg)
 

want more boost. only 7lbs now. looking for 14-20psi

with a good tune, no reason why you couldnt do it on a stock block....

but its not a psi level, its HP that you set your goals at..

Like everyone said, its a tuning issue.

Re: (Topdawgg)

and now has 430whp for 2 years in a row also beat on at the track...
stock h22....11.6 @ 119 mph a couple weeks ago...

Re: (Topdawgg)

i think you are the one that needs a search...

any motor is only as good as the tuning and quality of the turbo setup...

built or not...


what year is your h22? whats stamped on it?

Re: (Topdawgg)
 

It a h22a4 open deck block. The stock piston are the weak part of this motor.
