thanks alot,even for a 1.8 it moves perry dam good.just wanna get it to drive alittle better,falls out of vtec unlees i perfect shift a 9350.

sounds like a screaming engine reving out to 9000+rpms, get some pictures of the motor and the cam gears, lets take a peak to better help you get it straigned out. this is in a crx correct? whats done to the car beside the motor?

how much timing advance? why so rich !?!?!?

81mm bore?

i personally think cams are too big for the setup or is bleeding off too much compression, i.e. to lil dynamic compression so mess with the cam gears or get degree specs and degree the motor.

slowcrx954

81.5 the tunner aimed for that afr,he is a nationaly known.lance hes the cam gear pics,i definlty had the readings backwards i belive.


intake

exhaust

siregcivic

looks to me like its +1 intake and +3 exhaust get a better header

Uncle Dave

Tuned on E85 I think I read and I would run a GOOD 4 throttle setup on this engine and make use of the cams and sort out a better set of gear ratio's.

slowcrx954

yes it is tuned on e85,yeah a closer gear set will do wonders,header will really open it up,but motor was build for nos,no point in spending 1200 on a header for max 20 hp,or direct port 150hp for 800.seems like a no brainer to me.

Garrett

I always think the same, but I did a test https://honda-tech.com/forums/all-motor-naturally-aspirated-44/precisionautocanada-com-pro1-vs-pro2-dynotest-2684800/

And pro1 are always better than pro1 on 1.8L+ NA setup

slowcrx954

Thanks for the post guy,so sould I reduce overlap?the cam are degreed in now.also your thread show a stock gsr making more power on pro2,so why wouldnt a ported head and higher compression befeit?

Actually since he's using tuner camgears (1 mark = 2 cam degrees), it's +2 intake and +6 exhaust. Looks like those gears have been in the negative side before. If they were new for this build do a leak down to make sure you didn't have any bent valves.

Garrett

it was a b18cR engine

your setup need a decent header and exhaust system

do a dyno runs with the exhaust disconnect

slowcrx954

yeah its a ebay header,but im deffintly doing a open header run once i get a new dizzy.the whole engine is new,but the cam gears were on my old setup.motor feels great im going to post some runs later on.first 1.8 with a killer midrange,feels better then my b20/vtec.

If that wideband is correct that seems like a lot of fuel for e85. There is an extra volume of fuel in the cylinder due to nature of it. Your currently at approx .81 lambda. What happens to the power if you lean it out to say .89? In other words 13.0 displayed on the wideband?

DDTECH

Those cams aren't too big for that motor...
Those gear settings aren't correct, your using older style gears, Go back to your tuner and start at 0 on the intake and +2 on the exhaust.. your too advanced on your exhaust.. do the math, your taking too much away from your power stroke...
the only reason those cams seem sooooo big for that motor is because they aren't degreed in properly and the gear settings are all flubbed... TRUST ME please.. go back, reset your gears to what i said and re tune.

slowcrx954

the richer it was the more power it had.always a plus for a street driven car.

slowcrx954

thanks for your time all motor,it been a while and im going to redyno the car and play around with the cam gears.results will be posted soon!car has been leaked down,and compression tested.290 across the board,less then 3% leak down.

I have a similar situation as you. I too run the WS2 exhaust simply because I like the quietness it provides which is protection from the police in my area. I spoke with my tuner (james @ speedfactory racing) and next time I tune Im going to do a piggy back system. I will tune w/ the exhaust on AND open header. That way I can run my catback and benefit from a specific tune for the added backpressure but when I go to the track I can switch tunes to the open header to get peak numbers for racing. It will cost a few extra bucks but I will have the best of both worlds.
I will gladly drop 8whp on the street to keep the cops off my back and be able to drive up and down the freeway at 4k without hearing loss.

slowcrx954

i hear that!i dont have much problem with cops in florida,im tuned on neptune so i could easly save a new map switch for the track.i will post results of a new header 3in exhaust and cam tuning.

93egSLEEPER

Right on good luck. The cops in my area are ********. If its shiny it must be loud is their mentality. I got pulled over so the officer could look at my exhaust and hear it unobstructed once. He made me free-rev it and once he figured out it sounded like sex he let me leave. I can't say I dont blame them though, Im tired of fart cans always being obnoxious.

tempsohc

A/F's look rich?

DDTECH

He's gone back and changed it, i'm pretty sure he'll be more happy now..

a starting point should be like i stated above.. hope it all works out, if you need anymore help feel free to pm.

What injectors are you using?
On my setup, which is very similar to yours I use injector dynamics 1000s because the cost isnt much more than rc or similar, and I will never run out of fuel with my setup. The spray patterns are also supposed to be second to none, and they idle great.
My motor is a gsr block and head with itr pistons and a 2 layer head gasket. I run a 68mm throttle body and a port matched sk2 intake manifold.
I also run a vteckidd narrow header which alot of people say its not best for making hp, same with my ws2 exhaust. I went to the dyno with my full exhaust setup, but made a strait pipe for the muffler. So the pipes are still only 60mm.
with s300 and e85 I still managed to get to 210hp, with a blox tuner stg 2 cam also.
There def should be alot more in your setup. Do a comp and leakdown test, re degree the cams and try again.

slowcrx954

comp and leak down are good,im useing injector clinic 1050 cc injectors.well see what happins after a retune.

LHTBill

I actually have a somewhat similar setup. I have an 8hp power drop with VTEC at 5800. After a lot of research, I'm very confident that the problem lies with the WS2 exhaust. While I love the quietness of the exhaust, I'm not so happy with the power output.

Garrett

Invidia Q300 is a 70 mm catback and really quiet, it allow great power up to 220-225 whp without to much back pressure, after that I experiment some power lost
