JDM EVO 8 MR vs JDM STi 9 both running on 100 Ron Fuel
 

Which one would win in a drag race? ( evo 8 with hks jasma exhaust and sti 9 totally stock)
From standing start?
From 1st gear rolling?

anyone?

Evo 8

for sure?

The STI, but id say it would be close, do some looking about on youtube, find some interesting races between evo's and STi's ;)

Tony

wouldnt the evo have an advamntage ( its an mr) while thesti isnt a spec c... also the evo has an exhaust... wouldnt that give it an advantage?

I believe the Impreza would need an exhaust too :lol1:

Which Evo, i.e. running what power? Most likely the Evo as unless modified the Evo usually beats the Impreza in a straight line.

????

also all races where rolling with 1st gear

Does it really matter? Just enjoy your car.

believe me, i really am.... i just want it to be a bit louder... and if possible without changing the manifolds have the subaru burble

Well that's it, I'm selling my car ;)

Here are 3 equally as useful races

Standard UK WRX (220bhp) vs a EVO X FQ500 running race fuel
STi Spec C Type 20 (370bhp) vs a Standard EVO 8 UK
STi Spec C Type 25(cossy 415bhp) vs a Standard EVO 8 mr JDM

Sorry to seem negative but these unbalanced comparissions are totally sh1te but Japaneese believe it's good PR :nono:

IMHO

Tony

BTW I'm not knocking EVO's

I drove my JDM with STD exhaust it was quiet as a mouse, like a BMW :( and boring to drive :(

now I have a miltek 3" sports Cat and a Remap 350bhp and a hoot to drive, OK no subaru burble but make uup for it in Grin factor :cool:

Tony

t5nyw i believe that the 2nd and 3rd race wre about equal i mean come on: evo 8 with sti v9 ( ok so the evo has the advantage cause of the exhaust and decat but how much difference (power gain) does it give you?
also so there is no way tpo get the burble?
btw i was thinking of fitting a greddy exhaust(TRUST) with a jasma certificate.... (note: not changing downpipe or manifold)

Quite a bit realy ;) the spool up time is much less much more responsive

My JDM 06 STi
1)standard made 306bhp std on 100 ron map with 98 ron
2)standard made 329bhp with EcuTEK remap for 98 ron
3)Miltek Sports CAT system made 350bhp (257.5KW) and 460Nm with EcuTEK remap for 98 ron

BTW If you change the resonator (looks like a hot water bottle) LOL just before back box. will much improve the amount of sound ;)

:thumb: you'll notice the different get it rmapped and enjoy :D

Tony

i think i will! thanks! btw you seem to think that i should have walked over the evo 8 jdm as for your first of the threeexamples you state underpowered impreza vs overpowered evo but in the other two you state overpowered imprezas vs underpowered evos?
the fact is that both of our cars were jdm running on 100ron fuel( im talking about the evo 8 NOT the evo 8 mr) and he had a decat and exhaust, so it was reasonable that he won, wasnt it? ( the race was very close though)

...all I know is how bloody difficult an FQ 320 is to keep up with cross crounty.

Damn them and their electronics!!! ;)

yeah but whereis the fun in that ? (electronics i man)

Dont go the decat route unless you are going to have the car remapped but these engines in the new age twin scroll cars are stronger than the older (and uk) cars, but they still dont like being decatted.
A miltek (sportscat) system would be a good choice though, one for you to think about.

Tony:D

PS, never had problems with FQ320's, my spec c was quicker without a remap :D

Decatting is waste of time, and will not make your car any faster in real world driving.

:wonder:

Please do elaborate on how unrestricting an exhaust will not have any impact on what you define as "real word driving".

Think because it will blow an STI's engine up and you wont be going anywhere :lol1:

Tony

:) Rubbish, as long as you get it remapped once you decat it. Same applies to a sports cat.

The fact is that there is no mention of remap in the original post, hence "I" added it in one of my previous posts :p

Tony:)

i think i m going to fit just an aftermarket exhaust (from after the downpipe that is)... will i need any repprogramming or anything...???? the exhaust ofmy choice will be a greddy exhaust with a jasma certificate...

Firstly, an enhaust is significantly unrestricted by fitting something like a Milltek complete system with sports cat. You and I have identical jdm sti's 03/04 (for example). Your car has a remap with a decat exhaust, my car has a remap with, say, a Milltek sports cat complete exhaust system. Now both of us at the lights, or a long A road, the car you are driving will not be any quicker.
(Presuming both cars remapped by the same remapper).

Hope this helps.

Cat back does not require a remap but the gains in performance from doing this are minimal. People mainly do this modification for the audio and visual benefits.

Agreed but you said nothing about a sports cat in your post. The OP has a standard cat I believe? May be wrong. Hence why I stated either a decat or a sports cat (the latter is still slightly more restrictive obviously) and then a remap.

My point to the OP is simply changing the BB will not help performance very much, if at all.

True, soz, should have mentioned sports cat in my post!

I like your STI, lovely torque figure, I'm thinking of getting a silver or grey hawkeye JDM STI oon, sold my blobeye JDM STI and now driving a 330d M Sport!!!

Thanks mate, glad you like. Mine is a UK spec by the way, not a JDM. Does the JDM come with the 2.5 engine? Don't think it does. The twin scroll is reportedly a better turbo but I don't think you will see those torque figures easily from a 2.0ltr.
