ek9 and vxr

Yes but stock torque figure of the sti impreza is 343 N.m A EK9 B16B engine out of factory makes 160 N·m so with the curb weight of a sti type r(1260kg) it will be putting out 272N.M per tonne correct? A EK9 is meant to be 1090kg so that would be mean a EK9 would be putting out 146N.m per tonne? So even if I was to allow 30% transmission loss the subaru would still be making 190.4 N.m which is more than the EK9 with no transmission loss applied. Now you can calculate that for a b18c ek9 and it will probably still not measure up with the torque figure and in real life its good torque output which makes a car accelerate fast not bhp.

Good bit of sense that is mate...fair play.

I dont really agree on that one mate, My other car is a torque monster so im not being bias towards one or the other.

The torque only helps to give you the grunt from early on in the rev range right through unless you make all your torque higher up in which case its not really that useful to be honest. In racing you are never really at low revs so torque is not really needed IMO.

My particular EK9 i can bet my bottom dollar is under 1000KG now, and i am referring to my own in this.

Look at Formula 1 cars, they have hardly any torque i think about 200lbs(sorry i use lbs) but because they can rev so much and are so light with alot of BHP they are lightening quick. You dont need alot of torque to go very fast. Pretty much anything has more torque then the EK9 and alot more at that yet i can still blow past alot of cars with alot higher torque figure.

Revs + gearing will make good acceleration, thats how you can get away with a good torque figure.

Any engine will perform. Put a turbo on an ek9 yes it will fly, but then put an even bigger turbo on a VXR/scooby and will will also fly. From factory most turbo cars will run low boost on a safe map for everyday driving and useability. If our EK9s weren't so light they really wouldn't be a great performer due to their lack of torque. The light chassis really brings these vtecs alive.

Whilst turbocharged cars have great torque and can make heavier cars fast easily.

All depends how far you want to go.

exactly about the only post in this thread that speaks the truth ,

Yes you are correct somewhat in that BHP relies on gearing to provide pulling power. Torque needs gears to get high speed and power. BHP needs gears to create usable acceleration hence the understanding that it is torque that is fundamental to acceleration, not bhp... so proper gearing is essential to either:nice:
 
bhp is a measure of total 'volume' of torque aplied per minute...........If you think of torque as the size of an explosion, rpm as an amount of explosions that happen in a certain amount of time. then bhp is the total damage that these explosions create. then you can see why bhp is more important than torque.

I quite agree with a 200hp/sub 1100kg fwd honda will be beat a subaru/evo with sub 300bhp becuause ive seen it happen so many times.

bottom end torque is pointless on a honda if it's at the expense of top end hp, when you are going as fast as you can you never drop below 6000rpm

Nice explanation !

Also agree on the 200hp/sub 1100kg fwd honda's.
 
had my first encounter with a modified corsa VXR today, it had a slight headstart off the line, EK9 still pulled it back in, was really suprised tbh. Was expecting to get wooooooped.

VXR was popping flames like no tomorrow lol

BTW i thought EK9's were 182hp standard not 185? for the little difference its going to make lol, everytime i read up on the engine it states 185ps not hp.

Only on forums do i ever read 185hp by people posting.

i had a good race with one on some country roads and ewas glued to its bumper. there fast but not as good in the corners as the ek9!
 
i dont have any experience with my 9 up against any other cars but i switched from a 04 clio 182 and tbh the 9 feels slow until 6k revs and only then when vtec kicks in do i feel anything at all. i suppose my last 3 cars have had a lot of torque so im not used to.

BUT when going down a certain piece of land i used to get just over 130mph in the 182 up to a marker when i brake and i hit roughly the same in the 9. maybe not quite as much as the 182 but there abouts. higher revs and vtec must pull it back. i do wish i had more torque sub 6k revs though if im honest. (oh and its a stock ek9)
 
Well to put in contrast i raced an Arctic white one last night between 90-140 and he had a head start on the road as he wasnt in my veiw wen i started, i cault him up over about 2 mile of corners and decent straights then we came onto a long straight both at about 90 and i came past him whithout a problem, with both of us flat out it didnt take long for me to *** past, he seemed to run out of go around 115-120 but i was pulling him in and past as soon as we got onto the straight.

Dont know how it helps to compare as i was in an EG6 with full interior and a passenger so id say weighing around 1160kg but i have a std b18c6 setup on a b16a intake system, toda mani and full 60mm ss exhaust so id say at a gues runing around 190hp.

(just to note i was on a one way unrestricted road)

Personaly id say if it was between a std 9 and an arktic VXR the ther wouldnt be much in it at all but may sway in favour or the VXR
BUT a 9 against a std VXR id say the 9 would jus take the win.
 
i think that every one needs to get on track and sort it out once and for all. what a great day it would be. VXR's/Ek9's/Scoobys/Evos. all in a different state of tuning. safe enviroment, with straights and twisties. WINNER
 
Il throw up my 2ps worth. my Standard ek9 was slightly slower thAn my eg6 with an ek9 Mani and dc2 airbox. My b18 ek9 raped a uk blob eye sti uk scoob up untill 130ish my mates 319bhp version 5 sti type R spanked my b18 ek9 in every way. My 370bhp evo 6rs distroyed everything up to 140 mph limited lol. (0-60 3.8secs antilag & launch controll lol) it handled better than my 9 but didn't have the same amount of feel/feedback my 305bhp s15 has awsome feel but an ek9 would do it in the twisties cus I'm scared shitless of it lol. I'm stuck for what to get next now. That's my only problem. The only cars I want and not yet had are a r34 gtr and a 22b scoob or an evo 9GT

Finally someone who can admit a b18 EK9 won't beat a sti type r. Go for the 22b:D

trust me there are a lot of things a b18 civic wont beat. HA. had the chance to get a sti type r last year and pulled out. regret it now. 22B for sure.
 
A 318BHP would definitely beat a stock B18C EK9. Thats obvious. I was referring to a stock 270BHP STI. And i said they are about even, never said the EK9 wins.

Ive raced enough to know. Its not an opinion, its been proven :)

And there arent too many cars that out accelerates my 9 around the roads to be honest. There has been a few obvious ones but mostly surprised how many cars dont actually beat it. Its only a 1.8 N/A :lol:
 
ive raced a fair few poobaru's and have yet to get beaten

but i know that there are fast impreza's out there

there just sitting on a lift waiting for a new engine

:lol:

Should have come down my side when I had my sti type r would have sent you home with your tail between your legs lol.

And it seems there is fast b18 civics out there sitting on a lift waiting for a new engine also hey lee;)
