still no dyno or numbers for n/a out yet though

update: they said that the pricing will be 2200 on the last page.

i personally think that this mod will be great, especially if it really does bump our n/s midrange torque by about 30 ft/lb. whether it's worth the price or not is up to debate but it's finally out :D

and on their boosted racecar they got 99 ft/lb increase midrange iirc

 

no ****ing way are you for real?! u can just convert our motors to ivtec now? thats crazy

 

I doubt it will do that much for a NA car. Then you need AEM EMS and getting it tune on top of that. I'll just turn my boost up 1psi.

 

He first mentioned cost might be under 2k. If that were the case I was all about this but since its practically as much as a turbo kit and you have to have ems anyway....Id go turbo first.

 

Keep in mind that the "ivtec" really helps with mid-range, if you are looking for peak power then there shouldnt be much difference as long as you have your cams dialed in correctly. I am surprised they didnt rig it up for both intake/exhaust though. The fact that I have to "mod" a $1200 AEM EMS also turns me off.

 

Agreed. It's not cost effective.

$2700 - kit
$1300 - ems
$500 - tune

$4500

lol


Then I see the "complete kit" requires you to purchase this.


I have no doubt the time and r&d is worth the price, but it's still ridicules.

You guys are right, a properly sized turbo setup would destroy the "mid-range" gains they are marketing it for.

 

this is great for road race applications... even with a "properly sized turbo setup", the iVTEC conversion allows for way more mid-range power, allowing you to run a larger turbo and still have great response. that was the issue in time attack...

 

Sounds like a big waste of money. I would buy it for a all motor set up when you are gonna need all the help to get power.

 

x2!!!

 

We lock vtc on our higher hp NA K motors . . . So eventually with an NA f20c build you might get to the point where its not worth it either lol

 

^ very interesting

can you explain why, curious....

 

Well because when your going for all out power or building a race engine whats mid range or drivability mean?

Same reasons vtec is elliminated in all out race b series engines, theres just no need for it.

 

I stopped in and looked at the race car with the Ivtec yesterday. The valve cover was off and the work they have done is impressive. Hard to believe they have K20 cams in that s2000 head.

 

Hmm, I'm still not with you.

When we're roadracing, let's say our powerband is from 5k to 9k rpm. Even if it's an all out race engine, won't it still benefit from increasing the area under the hp and/or torque curve within that powerband to maximize acceleration on the track. It should still benefit even if peak hp isn't up as long as the average power in the power band is up right?

Where am I off?

Edit: or are you referring drag racing only and not time attack?

 

Its more like 6500-9k if you're gearing is setup correctly. Even then, usually a specific setting is better for full-throttle high rpm tuning within such a narrow rpm range. Plus, VTC has a tendency to be delayed compared to throttle response and does some funky stuff under true "race" conditions. During partial throttle and a wider RPM range it works great, but for WOT, high rpm only it tends to be more problematic then its worth.

I am relatively surprised that more people arent on board with this. Seems like a decent deal being that you get cams included and atleast back a few years, the S2K crowd isnt a bunch of broke HS kids driving their $1000 civics looking for a $500 turbo kit. Maybe things have changed though.

 

ah gotcha, makes enough sense i think :D

 

^ for time attack, i think its a necessary upgrade to get the proper mid-range power and torque needed with forced inducted setups. you definitely need the mid-range without having to be full throttle since mid-corner you won't be full throttle and need good response while exiting a turn.

we'll be building a time attack s2000 soon and planning on running the Design Craft setup, will keep you all up to date when we get started.
