Ok i been on this forum just trolling around for a few years, i builded my GSR, un-ported putting down 216hp on a simple *** setup. now my question is: what the hell are so many guys doing wrong...??? i seen so many 85mm builds with massive compression on the same cams i have putting down 10+-hp than what i have..

here is my current setup:
GSR block decked to .04 piston to deck (.032 quench)
oem bearings ceramic lubricant coated, on the loose end of clearance
GSR head with dual springs on BC4s (unported, machined .020)
P30 81mm pistons with gapless top ring, 2nd and oil are OEM (.010 machined intake valve pocket, .015 exhaust.. i think)
Skunk2 ported manifold with 68mm throttle body
Ebay hytech replicas
tuned by me.

I'll like to have an open discussion on how this other engines where build to improve the quality of others peoples builds in here and squeeze the most out of our oem builds.

 

ur dyno reads higher than mines??

 

it sound like your dyno reads a high. it sound like you have a 170whp setup.

 

Jesus...pick up a "English 098" book. Sounds like you forgot to mention the 50 shot though.

 

Same reason I make ~200whp with my setup and others make 200whp with a lot less.

Stop comparing dynos........

Do you run an ET that matches that WHP?

 

Probable did it on a higher than normal dynopack lol. That is a 185 MAX dynojet setup and I am being generous. What are your 1/4 mile times?

 

see my problem is, my track times never back up my dyno's

ie 196whp/140 and a 14.5 quarter mile lol (my first 4 passes ever...on street tires)

now at 203/140...hopingto drop into 13's once i learn how to drive.

 

is that correcting to flywheel hp? your time is similar to a jdm itr in a full weight dc2. they normally click somewhere around a 14.6@96

 

sorcery huh.. i never been to the track on this setup, forgot to mention is an 89mm crank. This was on a local dynojet, i also dyno the bucket on one of those trailer dynos at a car meet and pulled 209hp. I guess since i don't have Je or wiseco internals i can't be at that level huh..

 

I tune at the same place as killerpenguin21. I make ~199/135 and run 14.0@102 on regular street tires and 12.8@108 on 22's.

 

That's a Huge difference...

 

That dyno must be reading low.... Not saying i dont believe you but could post timeslips of both runs... I just want to compare the difference in times... What chassis is this by the way?

 

the difference i would see is that you can drive and i cannot lol. im in an EK coupe, not positive what marcel is in.

its possible, a stock gsr was run on the dyno last year, but i cant for the life of me recall what it made.

why do you think that? i have all factory internals (minus rod bolts)

this seems to be a simple case of you have high reading dynos.

 

The difference is a 4K launch and a 7.1K lauch. Also, my 60ft on street tires (195/60/14) is a 2.4. On 22"s, I can cut 1.7s.

I don't know if the dyno reads low. I too hate admit to this but we have a new puppy that go into my bag and chewed up all of my papers, etc. BTW, this is a EF with a rebuilt B18C motor. I have a plot of the dyno run on pg 15 in the dyno thread at the top of the forum. The car weighs ~2200 lbs.

 

It was your 1st time out. We need to meet up at island dragway one of this weekends.

 

I'm in to see how this dicussion goes. I'm going to be building an LS/VTEC soon. I've seen quite a bit of difference in HP/TRQ from the builds on this forum. Some say upwards of 220hp, while others are barely sniffing 190hp. That's with similar setups. Some guys have high end internals and still get disappointing Dyno numbers. I know tuning is a key element, but are there that many tuners out there that don't really know what they're doing? What gives? I'd like to get at least 200hp from mine.

 

yeah im trying to get out there asap, but i have some ridiculous issues with the car, due to stupidity both on my part, and people not being truthful selling me parts (think along the lines of something fell out...)

but why go after a number? why not go for a smoothe curve that produces useable power?

i honestly think my motor has 5-10whp in it with a normal manifold instead of itb's, and probably 3-5 with a different header, but a manifold would never give me as smooth and steady a torque curve and overall power delivery, and definitely not the throttle response, and a tri y would most likely add back the post vtec dip that i tried to stay away from.

 

different dynos and different engine building techniques...
Run it in the quarter and see what she does...

 

but why go after a number? why not go for a smoothe curve that produces useable power?

Useable/Streetable power is my goal, but I'd like to know how much power it is. If we were talking FI, then I don't think the HP numbers would be all that important. Being that I'd like to go NA, I'd like to know how much power the engine is putting out. I think 200hp isn't all that big of a goal either. I do agree with you that sometimes we (Import Enthusiast) put too much faith in high HP numbers.

 

unless he has a dyno sheet to post up he is bs. he said "builded". all credability went out the window with that

 

dynojet. nuff said

 

No idea on my power numbers, but on my 81.5 lsv build, I trapped a 13.6 at 104, on street tires and a gay koni/gc setup, in my crx. What do you guys think?

 

That's exactly what I'm talking about. then underachievers are calling bs on the dyno..
I try to give examples from my setup to see if people actually pay attention to stuff like quench pads, thermal barrier and dry film lubricants , maximizing their degree clearances.. blah blah. not just slapping a motor together with the best and bigger stuff and hoping for the best.

post counts don't stand for engine building IQ level...

 

YZF... I was making 267chp in 1997 with a stock stroke and stock bore LS. B18A1... Nothing new. So what.

 

maybe he is just the eastcoast "omniman" and his oem p30 piston motors just magically make more power than anyone elses. i mean, steve somehow managed to build a 200whp b16 without even pulling the bottom end from the car or honing the cylinders lolol
