Cant find my best run, 266whp 200trq at 7.7k rpm and 14psi boost 14.1 full interior and the fat ep chassis.

 

k20a3 FTW. what kind of mods does it have? i see its boosted

edit: nvm saw list. nice build up.

 

I think with better supporting mods such as tires/suspension/lsd i would have been mid/high 13s. But i live in cali-**** so i decided to put the car back to stock and build a side track car instead so i dont have to worry about cops bugging me on the street even though i dont street race.

 

Very nice.

 

interesting...i guess it does warrent a hood scoop haha, big ups to being different

 

it's pretty.

 

Looks labor intensive from all your pics. Looks nice though.

 

finally posting it up on honda-tech

 

damn, work that a3!

 

damn damn thats pretty nice.

 

Where did you buy this kit from?

 

wow that is pretty cool, much props, but it sucks its not that fast clutch that bitch

 

nice job

i would have gone with this hood IMO

 

I'm sorry but I think every1 iz entitled to a dumb question lifeline I'll use mine now. What is that?

super charger with a hottie top mount intercooler subaru style!

 

im sorry but that cf hood is flaming

rotrex supercharger system design for the Civic typer r.
*not fast because of bad support mods.. easy low/mid 13s car with right slick/suspension

*buddy club hood is design to let out hot air not bring in air.

 

the top mount intercooler, can it be fabricated to a turbo.

 

to be honest i dont know depend on your setup, and how big of piping your going with..

////found my last 4 runs on my k20a3 setup before i went back to stock and started my build it was hot like a ****///

Wouldn't ya know it, but Honda's own upcoming K-based turbo engine also has a top-mount intercooler.

That type of hood is used to disipate heat from the bay. He wants air to flow to the bay, not away, that is y the scoop is needed. Kinda why suburu comes factory with a scoop rather than a vented hood.


EDIT: i just read a few posts later and it sems like someone already posted about that.

 

Could you provide more information or a link about this? The one you posted above isn't working. Is this a kit, cost, ect... Thanks.

 

I dont know what it is but it looks cool ! :D!
