ok, i have 89si ef civic , 95 GSR swap, obd1 conversion, and 91 ls tranny , light weight flywheel, and light weight underpully, short home made intake, 450cc DSm injectors from 96+ talon, Hp headers, 2 1/2 catless exhaust, and dry zex kit , jet size .038 "75 shot" stock fuel rail, stock fuel pressur reg, stock fuel pump, pretty much


now i made 159.19 hp to the wheels all motor, tuned and
208.55 hp wit nitrous, 49.36hp gain on"75 shot? " what happend to the 75 hp? at least 60 extra , tuned with the bigger injectors,,or do i have the wrong jet size? the way it was tuned i run 2 chips, 1 chip all motor and when useing nitrous i switch the chip, , the car feels mean alright but i would like the extra gain on the nos ,

 

I think this belong in the Forced Induction forum. But if doesn't, I got this from rywire.com

310cc 200-220whp
440cc 220-325whp
550cc 325whp-380whp
660cc 380whp-425whp
750cc 425whp-475whp
880cc 475whp-525whp
1000cc 525whp-600whp
1600cc 600whp-800whp

 

Nos is kinda silly. Also it sounds like you have a pretty stock engine. what is the head like. Is the head "un-built"? get some good cams and tune again! By the way underpullies are a waste too and mess up your alternator and charging capabilities.

160 whp sounds low for a gsr, i guess not. You need to build it up some more.

My d-series builds have to be really built in the head in order to make a difference. Im sure its that way with most engines.

How is this forced induction?

what? guess again!

 

yea head is stock too , but i was told to get some cams by couple people too so i guess ill be doin that some time soon ,,

 

check out the sig

i made 84whp from a 75 shot.

ITR cams, Full Crower Valvetrain, ITR intake manifold, Edelbrock header, RC 440cc injectors, NX Dry Shot all tuned by Erick on Hondata S300.

Nitrous is...

BTW, this was all done with a catalytic converter, restrictive 2.25" crush bent exhaust to a stock style muffler. MAD NOZZ FTW!!!

Ermm something is wrong, i made 160 hp all motor and 222 hp on 75 wet single shot in B16. In my set up i have some hp loses, with another set up i hope gain some hp more...

160WHP from a USDM GSR is not at all bad. Remember that this motor only puts out 170HP to the crank stock. So this is not at all bad from a motor that just has bolt-ons. As for power when spraying, I can't really comment.

 

nitrous "hp shot" are not always exactly 75hp.

for instance, lower bottle pressure will mean less nitrous oxide and less atomization.

the same equates for your fuel injectors.


here are my calculations based off of 900 psi bottle pressure on a dry kit:

.022 - 18.70whp - 22hp
.026 - 26.31whp - 31hp
.030 - 34.85whp - 41hp
.035 - 46.75whp - 55hp
.039 - 58.65whp - 69hp
.041 - 64.60whp - 76hp
.046 - 81.60whp - 96hp
.076 - 221.85whp - 261hp
.086 - 283.90whp - 334hp

so, your .038 jet should really equal 55.25whp- 65hp (jet) 49.36hp gain is pretty close to what you can expect. what sort of plugs are you running and what is your timing at?

 

i was runing zex plugs, paid $30 for nothing , cause during tuning i fried da **** outa em, and the timing is delt with in the ecu so im not really sure, btw , dude i was lookin for a chart like this thanks so much , ill probaly got with a .046 and retuning to gain that hp, i wasnt really sure wich jet would get me there. i'll be happy if i can get 230 hp , dats it thanks alot guys for the input ,

 

230 will be fun as hell. just hope you have good rubber because you're going to spin like it's cool

just remember to keep the bottle pressure (temperature) up.


900-1000 psi bottle pressure is optimum. do you heat you bottle before runs?


some people use a bottle warmer, others hit it with a torch, i used to drop the tank into a bucket of hot water for about 2 minutes before i head to the track.

bottle warmers and pressure gauges are a nitrous users best friend.
