should i be making more power??.. Please help!
Last year i made 185whp and about 134 torque with a complete b18c5 with CTR pistons mild bolt ons and a DC JDM 2.5 header and ran a 13.6 in the 1/4mile...
Over the winter i completly rebuilt the motor with a crap load of new parts and only made 17whp more, so 202 whp and 144 torque. not to mention that i run a slower time...13.8.
I just got the car tuned and could not believe the low numbers... not to mention that the tuner(who i will not mention) set vtec at over 7,000rpm because that was the best place according to the graph....
A lot of ppl are telling to get it retuned somwhere else cuz i should be making A LOT more power!!!
Anywhays.. heres the setup. Anyone got a similar setup? how much power and torque and when does ur vtec come on?
Or did i do something wrong like choosing a wrong part??

haha what?? vtec at 7000rpm?? where the hell did he get that idea youre left with no powerband at all get it retuned most definitely theres a place called neetronics in the t.o. area try them i guess...your set up is similar to mine except ill be running a h/f g23 build...you should break at least 210whp with what you have done and what are you tuning with anyway you left that out...?
with all that you should be at or around 220 or 230 if you get it all tuned right.
vtec at 7k? why even have vtec at all. lol.

202whp and 144wtq out of a 1.8l and ur not happy? like d-rob asked, what was ur trap? setting vtec at 7k is irrelevant. if thats were it needs to be engaged for a smooth transition, then there it must stay. p1's in my old 18c1 was set at 6-6200rpm. Toda c's kick in at about the same range (7k). lastly, numbers without a chart is useless. it will reveal alot. i mean, you are n/a, so i'm really suprised how much more power u expected to make thru a 2.25" exhaust and funtional cat? i think the 144wtq is impressive for a 1.8, to say the least. but, why give credit to the 10ft/lbs increase, its all about the hp on ht. the numbers seem about right to me, but, the tq numbers are very good for 87.2mm, trust me. please don't tell me Nick tuned it?
I'm gonna agree with rollo......for the amount of work done on a 1.8L engine that is good power considering you only have a 2.25" header/cat/exhaust/muffler.
big n/a cams will require a higher vtec crossover point but depending on where the torque curve falls off on the low cam it "might" be on the high side.
post up a dyno graph so we can see what is going on.

Anywayzzz... i posted my time slip and dyno graph.. let me know wut u boys think. Also instead of using a wideband in the o2 snesor bung, he stuck a probe in the tail pipe... I think that might be an issue also..
Im gonna get it tunned again soon.

Thats in an eg hatch right? throw a slick on that bitch, and ull be running 13.0 at least, get some track time and that power should put u in the 12's. dont be to disappointed with that power ur running 2.25 exhaust and a cat. i still dont think that vtec issue is right though...
strange, your peak torque is the bump at ~4500 rpm (probably due to intake resonances). after that, it steadily declines until vtec, and then after that, the highest torque you make is around 135 ft/lbs at 7600 rpm. It doesn't seem right that you are making more torque at 4500 than at 7500.
do you know what your A/F ratio is doing?
what car is this in? 100mph trap is decent, but it seems like you should be faster than that. you didn't by any chance to any brake work since you put the motor in?

I agree with Rollo about the 2.25 inch exhaust as well. Anyone with expectations of putting down more than 190whp should be putting a full 2.5 inch system in their modification plans, without question. This is definitley a problem area for you right now.
I feel that the 70mm TB is hurting you as well, it is too large. I'd drop that down to the 64-66mm range, portmatched to the IM intake port, of course....or have the TB 1/2 mm larger than the IM port to speed up flow in the IM plenum and create an anti-reversion effect.

cuz he sucks c*ck, thats why. he completely disrespected Gord Bush and his 30 years of building race engines and i will never reccommend him to anybody. he actually had the nerve to tell me that my old c5 i sold a friend was missing an o ring in the block, and was not making any power on the dyno. 140whp to be exact. i cussed him off and told him obviously vtec isn't working. my boy calls me back half hour later and nick was in the process of removing my boys vafc that was still hooked up. yes, he was attempting to tune with a piggyback still controlling the solenoid. punk bitch. anyway, by looking at that graph, it looks like his crappy tune. i could be wrong though. anyway, the power is good, but that spike at 4500rpm must be intake resonance. actually, other than the 202whp, that tq curve looks like my 81.25mm, 10.6/1 c.r. gsr motor with p1's. 101mph, trap? hmmmm, seems a bit low for a 200whp eg. is it a hatch? how much does it weigh? lastly, i've always believed that 1.8's don't love these huge cams, unless the set up is maxed out. not saying p2's aren't good, but, possibly too big for ur motor...other than the other things that are holding u back (cat, exhaust, possibly the tuning, bad ht advice)

in ur motor. were talking about a different set up here. everything is different. from builder, set up, to tuner, elevation. etc. and d-rob, we both know that s2p2's is not solely, the reason for ur coupe to trap 104ish...come on. u have some other parts in there that are quality and proven also. not just the cams

I honestly only see the 2.25" collector header being the main hinderance of this engine.
I trapped 104-105mph on a DC Sports JDM 4-1, test pipe, and DC Sports 2.25" catback. Also on an unported B16 head, and an untouched AEBS manifold.
His engine is begging to be revved higher.

I run 13.1's @ 105mph all the time at Cayuga with slicks and a 190whp LSV motor. You will definately need slicks to go faster. You are slower now because more power needs a better tire to grip the track. Simply put, the 2.26 60 foot is killing you. My 60 foots are high 1.7's and 1.8's consistently. I bet your tires are spinning like crazy. Improve your 60 foot and it will show improvements in your overall 1/4 mile times. PM me if you like and I'll help you out a bit with your set-up, I also have some Q's.
Nice numbers with the motor

I also agree with D-Rob, a bigger exhaust and better header will also help make more power on this engine.

made that point long ago. and even then, i remember recently seeing a motor with a dc header w/2" collector make just under 200whp. so in the end, its all relative

It is probably running too rich if the wideband was after the cat. put the wideband before the cat and check the a/f. Also, that isn't bad whp for a 1.8 If you get another 10whp you should be really happy for that setup. -gotta love the torque from the pro2's on a 1.8

If anything, maybe around 6600, but that only addresses a minor issue. The whole powerband looks a little low.
What are the cam gears set at?

well seems like if vtec was engaged earlier on the power band would be much higher and would of peaked higher at the same rpm (eg. 8k)...i know all motors don't perform or act the same but still...i think there is a lot of juice left in this motor...
OK.. so i posted a slip i found from last year... thats not even my fastest time.... but anyways... that build was a type r with CTR pistons. bored tb and im, and a dc sports JDM 2.5" collector... it mad 185whp and 134 torque.
Can someone tell me how i got a slower time this year if im making more power and torque??... same tires, same car.... if anything a good 60-70 lbs lighter this year!!!
