[B]well then there's no point revving past the stock redline. You say you shift at 7500rpm. When i had a d16z6 i used to shift at like 6800, you can feel it stop picking up past there. Here are a few links to dyno graphs that'll show you what i mean.
Check out where the hp line starts going back down. Right where the hp starts to drop off is where you want to shift.

 

i feel sorry for your engine, if its stock at least. If you have stiffer valve springs then its a different story, but still the stock cam doesn't make power that high.
Honda made the redline 7200 rpm for a reason, reliabilty, power, knowing the enigines limit, these were all things considered when determining the redline. But hey, what does honda know?
I hope you don't make a habit of revving to 7500rpms on an engine with 219,522 kms

 

Well said. The only thing you can expect from increasing the redline on a stock motor is a nice, fat repair bill.

 

Hey I do not rev usually that high..
now.. My bros car has about 130 hp.. mx3 v6 gs.. its lowered I believe.. I do not think they come stock that low.. he has a system in the car..Hes got a preformance exhaust...
Ive got a 92 Si... with preformace exhaust.. no system.. I have small amp and speakers no subs my bro have subs..Im running about 125 hp...
Im assuming exhaust does not add alot of hp.. my exhaust is big and loud though.. lol
my bros car has "ram air" apprantly which means he cant add a intake because it already has a stock one that is good.. compaired to the crappy honda one..
just want to see what I can do.

 

revving past where your engine stops making power will make you go slower, thus making you lose to your brother.
There is no such thing as cheap power. Making good power costs money, and lots of it.
Trust me, if you want your car to go as fast as possible, shift at 6800rpm.

 

having to shift at high rpm will make you loose your momentum and you just go slower.

Trust me - I used to have a cavalier - used to do it all the time. it was bad on the engine but it survived- the transmition on the other hand went bye bye. as soon as you hit 6800, 7000 you should be pressing the clutch.

As the guys say- more speed = more money - if you dont put in the money you will end up with problem after problem. Lighten your car and you should have no problem beeting mx3. Honda will survive a lot of things.

I was wondering if any of the fuel addectives acually work - has anyone tried??


Like the one in crapy tire - nos - "increases horsepower"- anyone tried it

 

I cant really lighten off.. I was thinking just if theres any cheap add ons.. that will just give A bit of a boost/advantage..

 

I wouldnt recommend a raised fuelcut on a stock engine. Theres no need, your already pushing the redline by far.

If you have bolt-ons i suggest a reprogrammed ECU. Yours will cost aprox $50 for custom program and reprogrammable chip.

With bolt-ons your increasing air flow without increase fuel you wont get sufficent gains. Extra timing here and there always helps out too!!

I shift at 8000rpm. Stock redline. Stock engine. No need to go past for any reason. Unless you have REALLY long gears.. and your trying to get back in the powerband.

Its one thing to 'maintain' power past redline but are you really making anymore?

Goodluck.

 

Revving up any higher is pointless. Your cam's aren't making power up there your just getting valve float. Also the Tensile load on connecting Rod's goes up exponentially for every 1000RPM. Therefore an Engine making 500hp at 6000RPM is about as stressfull as making 280hp at 8000rpm!!!!! Rev's are VERY hard on motor's. Turbo's are so popular because if your making 100% more power in the stock powerband the Stress on the internal's is only going up about 60%. Hence why Big V8's last forever. They are revving so low the engine isn't workign that hard. You want to go cheap for fast make sure you dont' slow your car down with Rice boy mods. Every 1lb of unsprung weight is like adding 4lb's to the car. So big rims' that are a heavy are addign alot of weight. And if the rims are wider your adding more drag as well as decreasing brakign performance. Sub's and Big system's will slow you down as will skirts and wing's and what not. Try to keep the car light and throw some Bolt-on's on. www.torontostreetracing.com has a HUGE for sale section. There's ton's of Honda bolt-on's for really cheap. And if you wanna wreck for minimal money there is always Nitrous. There is no cheaper way to get 50hp. Period.

 

you might wanna edit out that part concerning that "other" site, we don't need to mention it on here, we have our own for sale section that is very good, if anyone wants to go to the other one, they can find it on their own

 

Yes but TSR's for sale section is absolutly massive!!!! I haven't found another site that has even half as many Honda parts as them. i dont' condone street racing and I don't even post on that site. But I did buy a Tranny and Motor mounts from the listing's on there. If it was any other car Id say jsut look around. But 80% of all the parts listed in there for sale section is Honda stuff. So if your looking for cheap bolt-on's TSR is one of the best site's to check. It pay's to shop around.

 

Ya, your right...
but the thing is, i dont' give a s*h*i*t about this engine or the transmition, because i'm getting a B16a2 pritty soon, and no, i'm not going to beat on it like i do on this engine

that engine will be my little baby

 

are you going to a circuit track or a drag vs. your bro???

if its drag you lose no matter what..

if its circuit..... get some bomb azz tires

 

who's that question towards???

 

lol ur gonnnablow ur motor lol

 

wana go fast w/o breaking ur bank? strap on a turbo or sum nozzzz

 

Wannna be quick, Put Boost on yoru D-Motor and Run 14's. Wanna be fast!! Then Go B or Go home. At least you can Run 13's with a Mild B-engine.
