I beat a TYPE R. WTF

[sacestar836]

friend of mine has a sr20det nx2000 with a ballbearing t28 3 inch hks bigass downpipe pistons boost at 12 psi dynos 300hp (well...297)

edit - has yet to get his ebc....used a friends mbc and set it to 12 for daily until he gets the ebc

A Type R isn't the fastest 4cylinder on the street... having a completely free-flowing exhaust is actually HURTING his performace. N/A 4cylinders NEED the backpressure of an exhaust. Intake won't do much either... and the car was light to begin with... why someone would gut a Type R if it's their street/daily driver is beyond me as well. A decent driver in a 1G GST should have no problem with a Type R... do yourself a favor though and perform all the free mods before your next race. Maybe get a K&N Filter, and go the ghetto race exhaust route by disconnecting your downpipe from the o2 housing, but leave the exhaust in place ("I just have a bad exhaust leak I can't track down officer" worked for me a bunch of times) Then you can bolt it back up (if you want to, but why?)

HAHAHA since when do cars need backpressure? LMFAO .

You should OWN him. They are not so quick.

Actually NA engines need a certain amount backpressure or they start losing low end torque.

Highly modified ones dont want backpressure Id imagine though.

Actually AlecW81 is right,your wrong, N/A cars need backpreasure,a freind of mine has a Gen2 RX7 non turbo,and he is running like crap because of the huge flow he has, he has 2.5 inch headers,and independent dual exhaust..thats way too much flow for a N/A car,turbo cars like ours dont need the backpreasure the best thing for turbo cars is a huge pipe going out the side of the car....but that would be eligal

A friend of mine has that setup on his 1.8T Jetta. It sounds amazing. He has a resonator and a high flow cat but no muffler . After the cat it comes out from both sides of the car.

 

[WhiteCharisma]

thats tight....those VW turbo's are tiny yet they run pretty good,but VW's engine wise they arent very good most parts are plastic,plastic water pump,ect. everything melts if the car overheats,and when something breaks,get ready to pay some good money....

 

[AlecW81]

Meant 200sx... my bad. Basically the same car anyway.

As for the GM and variable valve timing... look that up specifically... not the displacement on demand technology. I would, but I'm in Iraq and don't have the time (or fast internet connection) But when I sold Chevy's and saw that they featured VVT on the NEW 4.2L I6, I was impressed... then one of the mechanics at the dealership mentioned that GM invented it back in the 70's for Cadillac. Maybe he was mistaken, but I'd take the word of a GM mechanic w/20+ years of experience over someone on a forum.

sooooo, what now? do i have to prove that toyota vvti came later?
T.C.

that's nice, but vtec was first introduced in japan for the 1990 model year crx si-r.

For all the people out there who don't know how VTEC works (pretty well all of you) is as follows: Honda VTEC cams have 8 lobes on each camshaft. Four are smaller for low rpm drivability and the other four are the VTEC lobes which are larger. The engine computer tells the VTEC solenoid valve to open (about 5500RPM). This sends oil pressure to the end of the intake and exhaust camshaft, moving them over so the larger cams are now engaged.

on a b-series there are 12 lobes, actually. vtec doesn't create MAD TOP END YO, it simply carries a stable, flat torque curve much further than one cam lobe would be able to.

WOW ALOT of you guys are MISINFORMED. I can quote many sources if you guys would like? BACKPRESSURE IS the ENEMY. At all costs you do not want backpressure. You want "high stream velocity", which is the speed of the exhasut stream. NOT backpressure. You have mistaken backpressure for stream velocity. If you put a 3 inch on a 420a you would lose tourqe becasue the stream velocity wont be as fast. NOT becasue of lack of back pressure, tihnk about it. How would backwards pressure towards the engine help power? It doesnt. Done...next?

 

[AlecW81]

Whatever you say Eclipsed... No matter what facts we throw up in defense of the need for backpressure in N/A cars, you'll come up with some B.S. that applies to turbo cars and not N/A. For further explanation of that statement just see your own statement above this... Yes you want high stream velocity on exhaust, I'm not saying every N/A car should have a 1" exhaust pipe, I'm saying they need a LITTLE backpressure. Hell even those fools at SCC (or one of their sister publications, Turbo, Import Tuner etc) mentioned that N/A cars need backpressure. (It was in one of their Turbo 101 articles a while back) Now if those hacks (who usually never get their facts straight) can grasp the concept of needing a little backpressure in a N/A car, maybe there's hope for you... but I won't be holding my breath.

 

[vertGST]

this kid i know has a h22 prelude and he made the MISTAKE of cutting his exhaust off. Not only does it sound like shit but the car is noticably slower as well. N/A cars do need some sort of back pressure. But i am not gonna jump into an argument that someone will not give up on.

A friend of mine has a 2001 Prelude, and another has a 93 MX6; what diameter exhaust would you guys recommend?

 

[sacestar836]

2.5 at the most

V-tec is a marketing ploy more than anything. People go, wooo v-tec I want that. . My cars got V-tec!!! hey look my nissan has variable valve timing too, so does my toyota, so does just about every other damn import car out there.

Its not like my car has Multi port fuel injection written on the side in big letters. Its nothing special, just like v-tec.

Speaking about this, my '86 Toyota MR2 had a two-stage variable something too. I noticed at 3000rpm something opens up and makes it loud, then at 4500rpm it's ultra-loud. It sounds cool when i rev from 1000 - 7500rpm because it sounds like a 'lil ferrari.

 

[WhiteCharisma]

ferraris sound amazing..hmmmmmmmm?????? a mid engine eclipse rear wheel drive... that would be so fvckin kool...

vtec kicks in at 5000 on my civic and on intergras but i have to agree with you vtec is not the one stop answer to speed. Hype-R's are not what people make them out be

[eclipsed95]

Did this thread get way off track or what I can't believe a mod hasn't closed it.

 

[WhiteCharisma]

oh well.....

 

[AlecW81]

I'm tempted to start a "backpressure" thread just to see how many people slam Eclipsed like Shaq

NO read what u said. You dont need back pressue. You need high stream velocity. Backpressure is not what you need. You are tihnking about it wrong. Think of it this way. You want an exhasut that will be able to give you the right amount of stream veloicty, and not sacrifice torque. So you get an exhasut that will provide that. If you get oen thats to big the stream velocity would be crappy, so it flows less. A little Bckpressure wont give you more stream velocity. It would slow it down. I really dont see how you dont understand this. Post in the Advanced forum if you dont want to listen to me.

I guess Horsepower TV, Mustang monthly, Hot rod, and other such mags are wrong also? HUH?

Most of you are pretty damn retarded and ignorant..."Type-R's are overrated" "V-tec is overrated", "V-tec is a marketing scheme".

V-tec is a great bonus to any honda motor, when it kicks in you really do feel it and appreciate it. I'm not saying it boosts your car like a turbo kicking in, but it's something! Imagine having something extra to help yuor car along without the hassle of maintaining a turbo. No maintanence...again Hondas are fuel efficent cars, economically efficient. Save the gas from turbos, keep the engines small, so what if they have V-tec.

Someone said well if it's so great why doesn't everyone have it? Duh, maybe because that's what Honda specializes in? Do u see everyone having a supercharged v12? or proximity detecting devices for parking like mercedes has? Do you see everyone with carbon fiber pannels to cut down on wieght? NO, y? because companies research into their respective fields!

Type-R's are not overrated, "Oh, my stock DSM is way faster!", try it at a track buddy, that's what the R is made for.

I would love to own a type-R but that's not happening. Hell I'd love to own an AWD DSM, but that's not happening either, but all of you seem to determine a whole car one a few lousy streetraces. Grow-up.

My friend has a type r that gets 13mpg...maintaining higher rpm w/ VTEC activated makes it pretty inefficient, eh? (he drives really fast) But still, that's crappy mileage.

The RX-8
14.45 on a 1.3l

I'm still waiting for more timeslips to see what they can consistantly run.

Back on the subject. I can see a stock GS-T beating a Type-R, It doesn't seem too unrealistic to me.

dual stage vtec b-series??



the newer rsx-s has dual stage dohc vtec, and a few of the vtec-e sohc engines had dual stage, but still the same old exhaust lobes

anyone notice how most of the "truly" fast hondas are all turbo'd?

 

[Nomad666]

I just wanted to let you guys know that I raced him again and lost due to too much wheel spin. We went from a stop to 3rd. He had me by about 3 cars. I didn't want to start a new thread but still wanted to update ya'll. His mods again are:exhaust, intake, cam gears, fully gutted interior. My mods are: removed BCS(hehe).

Edit: he used 94 octane gas and I use 91, would that make a noticeable difference???

 

[vertGST]

just like stated somewhere else int his thread car companies have there own versions of "v-tec" my wifes celica has vvtl (variable valve timing and lift)the car gets noticably louder at ar ound 5k but there is hardly a difference in performance that i feel. not like its a performance car anyways.
