Throttle Response After Bov Installed...

[skunk]

hey guys, I have a question re. the installation of an after market BOV.

I recently put on a stealth FX BOV on my T. its an awesome product however I have a question regarding throttle response.

I havent been able to drive my car properly since I installed the BOV only untill today due to an injured knee ( cars a 6spd man) neways, I drove it today n noticed that the throttle response wasnt as good as when I had the stock BOV on ? am I imagining it or could this be true ?

if so, what could be the cause ? its currently venting to Atmos (50/50 setting), so perhaps this could be the cause for a slight differnce in response ? it still boosts fine when I give it to it ! (sounds great too lol)

iv read in other post bout ppl saying that they totally remove the BOV n have a stronger throttle response.

any advice will be greatly appreciated !

cheers

btw, im pretty new to this all so please be patient, esp if I ask a stupid Q lol

turn it back towards plumb back, it should help a little

thx senna, yeahi figured that just as much after I read up a lil more lol... how do guys with after market BOVs get maximum throttle response? or...u cant? ill have to tighten the springs a lil more n see how that goes..

thx once again mate.

I'm no expert but yeah I'd suggest increasing the spring rate a bit more by turning the thingo... maybe that will stop it opening as easy and keep a bit more boost inside the system.

Mind if I ask where you purchased it from, and how much? you can PM me if you want.

Cheers.

what will help with throttle response is shortening the lenght of the piping so a propper inlet and cai will shorten the piping by over 1m which will result ina big gain

If you really want to sharpen up the throttle response either screw it down so hard it doesnt open at all or pull it off and bin it.

now lets not start that debate again

skunk - its not gonna be quite the same even with it all the way down, but you'll get used to it after a while...

The best throttle response it got when using an after market BOV was when i has turbosmart adpator pipe fitted. I had my V port mounted on that and the stock plumb back mounted on the cross over.

It plumbed back at low boost throttle closing and vent to atmosphere at full boost throttle snap shut events. Ninka runs a setup like this now. It also quietens down the intake noise when you get off the throttle.

After I fitted my Stealth FX I went out and tried it in all different settings doing hard shifts from 2nd to 3rd - I tried PB, atmo, 50/50, soft spring, hard spring and 50/50. Mine is fitted down by the throttle body as I have Nizpro stage 2 plus. I can confidently say that the least amount of lag, for me, is 100% atmo and hardest spring setting. Taking boost away at the butterfly clearly has an impact on throttle lag, for me anyway. Somewhere on this forum there is an excellent article by Simon Gishus that explains why.

Hope this helps.

thx for all the input everyone, yeah iv played around with it a lil bit n have actually turned it down heaps more so that it doesnt vent as much into atmos now. seems to be a lil better altho I will have to try out the different spring settings.

sorry but yeah I dont mean to start yet ANOTHER BOV debate lol.

cheers.

velluto, ill give your settings a shot n see how it goes ! altho im only running a stock settup. no nizpro kits ................yet.. lol
