Hi guys,

I've got some tubing, couplers and a new filter to make a CAI for my Vortech.

Will this effect my tune at all? (Uprev)

I assumed since Uprev uses MAF inputs that if there was any pre-maf flow change the fueling would be altered accordingly, but a couple of people have advised me to get it re-tuned.

Thanks in advance for your help.

 

As long as the MAF tube is exactly the same diameter as before you should be fine.

 

Not touching the maf tube, just adding 3.5" piping to the vortech intake to get the filter behind the bumper.

 

You are probably adding only a foot of piping to it. I dont think this is an issue. If you have a wideband just make sure its spot on after the install. But if your concerned about keeping inlet temps down for a lot less than a tune you could just add a vent if you could do it yourself.

 

Thanks for the replies.

I can't decide if I want to cut a hole in the bumper for the vent yet as I love the the smooth lines of the OEM front, although it give a more aggressive look.

This is why of gone the CAI route for now. I did get the K&N RX-4140 filter in case I decide to fit the vent at a later date.





Do you think the vent would give better results then?

 

it won't affect the tune.

It will draw in cooler pre-charger air which might help a small amount in intake temps but it won't change flow. Intake temps are compensated for by the ecu so the iats might stay a little lower and as you get on it the car won't pull as much timing.

being that it's pre-charger air it will be a minimal effect since most of the cooling is done at the intercooler anyways.

 

Cheers guys, I think I'll go and have a go at fitting it now. Its a lovely evening here.

 

All done, Cheers.

 

looks good.

I would try to adjust the angle so it's not behind the crash bar. That will help it get more direct air. Otherwise the air has to go under and around the crash bar to meet the filter.

 

well I can think of one thing that will affect it.. with mine, the stock filter was so bad that when I added my CAI onto the vortech I gained 1.5 psi of boost.

 

Is there any benefit in doing this?
I need a replacement air filter....

 

this is strange since a freer flowing system will have less backpressure therefore less "boost" (boost is only a measure of backpressure in the charge pipes).

in theory it will bring in colder pre-charger air. Any testing people have done shows that it doesn't affect power at all but I could see this a benefit maybe if you track the car since the heat in the engine bay would continue to build up and eventually cause the pre-turbo air to become very warm.

So basically if you tune it with good flowing air it will keep your car more consistent tune as you drive the car hard for long periods of time instead of slowly raising the intake temps over time. This also depends on how efficient your intercooler is since that's where the compressed air dissipates all of it's heat.

 

I think because my stock filter was crushed and a bit dirty / old it was just restricting that much air..

 

clean your dang filter ya hobo!

 

fyi

 

hahahahah, that is one sad looking stock vortech filter on the ground.

 

What was the length on that tube rob?

 

I dont think this is an issue.
