Modifying the vs s/c cai .... yes or no?

[FirstVR_JC]

I just yesterday got my harmonic balancer replaced .... and now have noticed that the mechanic has made a mess of my cai when taking it off or putting it back on.

it now wobbles all over the place, the tappet rivets are shredded and there are now gapping holes and multiple drill holes . The rivets are now useless and the cai is no longer firmly attached, may even find it difficult to find a place to attach a new one. So now i have to fix it.

My question is .... In the pic attached you will see what i did to my current cai thinking it will flow more air.

Can i get you guys opinion if this is a worthwhile modification and do you think it would have any benifit .... I plan to get a new one and would like to know before i go cutting that one up.



Thanks.

sounds like your mechanics a moron. just open it up with a heatgun. same effect, but wont look like crap

So there is a benefit in opening these cai's up as i have done? I cut my current one like this and wondering should i do it again.

Got my car serviced a couple days ago at the automotive workshop i have chosen... needed radiator replaced also and they did a fine job of replacing my cai.... needed HB done asap so put the car in quickest place i could. He obviously used a power tool when i didnt need too.

When GMH engineers designed the S/C CAI they would have picked the best possible design for maximum performance and thoroughly tested it in a wind tunnel.....otherwise they get the sack!
That's the theory - if you alter the design you also alter it's performance.

But there's nothing wrong with a bit of individualism and who's to say it cannot be improved upon....so if you figure altering the design improves it go for it.

ive seen heaps of VS CAI with that whole centre cut so theres only the 2 screws on the end.

ive heard its a improvment.
im gunna give it a try, possibly this weekend

Thanks for the response.... i was thinking the same thing as the information you provided --- if it worked better with a bigger inlet than presumably they would of made it like that. Maybe it decreases the ram effect with a wider inlet ... just looking for some confirmation from someone that knows more about engine workings than myself .... cheers

i noticed the ss induction version for my model commodore has quite a large intake opening .... that is where i got the idea to cut it from ----- similar air intake opening, just $350 cheaper.

They may have sacrificed some performance to cut costs however?

ding ding!!
i reckon too^
