Custom Plenums (intake manifolds) for CA's

[ISL33P]

Just wanted to get an idea on what people think of this design. Loosely based on a GTR style design. Feature:
- completely rolled bellmouths (tested to be the best for overall flow)
- available for a variety of different throttle body's

Volume is underwrap until testing is completed. Sorry about that.

Complete flow bench results compared to a standard turbo inlet on a standard turbo head will be available soon, with dyno results on a mild CA just around the corner.

Following are some photos.

Prices are yet to be calculated. First i need to gauge interest.

Thanks,
ISL33P

If I'm seeing velocity stacks in that last pic, count me in for sure! (unless the price is too exorbatant) Do you know where the TB is going to sit in relation to the stock manifold? (am I going to have to adjust my intercooler piping) Thanks, and keep us updated. I really want one of these!!!

[iliketocrash]

see... now they don't show up for me at all. this blows. i don't like these new forums. i don't get e-mailed when a thread has replies, i don't see attached images, and i can't put new skins.

[BoroBoroS13]

I see the pix just fine...

Looks like a really nice piece of work too.

Bye Bye variable intake
I'm sure the superior flow etc would make up for it, besides, who needs low end torque?

[float_6969]

Actually this wouldn't get rid of the variable part of the intake unless you removed/disabled the butteryfly's....

[Projex240]

keep it at around 400 for the intake and the interest will shoot through the roof, I promise. Alot of companies can make these kinds of IM's but get so greedy that they jack up prices,a nd no one wants to buy, so they abandon the product's production. Keep that one competative with an sr greddy IM and youve got yoursefl a hot item.

Count me in if they are priced reasonably.

Thanks for the feedback guys.
iliketocrash - if you want i can email you the photos if you like.

Yes they are velocity stack, bellmouths, whatever you want to call them. They do the job and have been tested by a local (Australian) V8 touring car team for the best allround design.

From first dummy fit up, you will need to modify your intercooler piping and block the water hose for the throttle body (unless you keep the original, not recommended). It uses the manifold but cut and machined to suit.

Prices will be in the $AU500-$AU600, which equates to around a max of about $US450 plus frieght on current exchange rates, but this may come down slightly.

The problem with the Greedy style is that they are cast aluminium which does not disperse heat aswell as the aluminium is use. Just something to think about.

I am calling an engine builder today to sort out some flow bench testing and i will let you know as soon as i have results. The first one is going in a P510 sedan with a ca18 that is currently making 155kw at the rear wheels on 15psi with a standard T25 turbo.

[float_6969]

That sounds pretty fair of a price. Do you have any weight guestimates to figure shipping?

[boost_boy]

The plenum looks nice and I hope your intentions are good, but I have to interject. Is this something you do yourself and will be making a couple or will this be mass produced? If it is something that will be mass produced, commercial posting is not allowed without setting up some type of vendors account with the administrators and/or forum owners. Your honesty on this matter is greatly appreciated.

And your willingness to want to provide innovative products for the CA18DET is accepted by our community, but we as moderators have to make sure that everyone plays by the rules that are set forth for members to follow. Please feel free to voice a concern on this matter or ask myself or anyone of the other moderators questions pertaining to this matter.

Sincerely,

Dee

the weight is 5kg max.

yes i am willing to become a vendor. i am currently just gauging interest and trying to determine a decent price for people where ever they are located. they will not be avialable until i can determine the effect they have any any given cars performance.

please email me the details and i will get back in touch asap.

[boost_boy]

Thanks for being straight-forward "ISL33P" . I'll get you pointed in the right direction and if not, Ryan (float_6969) will definitely fill in the blanks.

Dee

[ISL33P]

Thanks.

Float - can you let me know what i need to do.

Thanks,
Ariel (ISL33P)

[boost_boy]

I've contacted the senior administrator for guidance on where and/or who to direct your inquiry to.

Dee

[rico05]

If it is less than $450 shipped, I would buy one for sure. Keep us posted!

[boost_boy]

Hey Man,

I've emailed you the necessary info that can get you and your company signed-on as vendors.

Dee

[ISL33P]

prices will be determined soon. i will keep everyone updated.

just waiting on response from website owner regards sponsorship and i will let you all know.

what are expected freight costs to US for 5kg or approx 10 pounds.

[float_6969]

ISL33P, thanks for the honesty. I was actually going to send you an email about this matter today, but good ol' Dee (boost_boy) beat me to it. Anyway, most of what I had to say has been covered, and if you are on track with advertising then I'm excited to see you on board and I hope that we call all start supporting eachother soon!

[fanta]

ISL33P, please e-mail pics of the intake to slipstream742@yahoo.com

[Trigger]

yeah i cant see the picture neither...if you dont mind or someone that can see the pictures can you send me them at Tim3882@hotmail.com


thanks Tim

[ca18datsun510]

ooh ooh, me want.

count me in.

why does all the good stuff come from australia?

[ISL33P]

i have just sent you guys some photos. let me know what you think.

feedback can go a long way. it has already help me narrow down a price range.

thanks,
Ariel

[ISL33P]

i have sent greg an email and i am just waiting on a response.

[cortina-mk1]

i think the flow bench results are going to be important in determining how many sales.

the factory plenum is very good on its own after some subtle work.

[ISL33P]

i agree, i just want to find out, backed with some solid evidence, that there are restrictions even when testing on a flow bench. if there are, the restrictions will be multiplied when a turbo is added to the equation.

the flow bench can not take turbo pressure into considertaion, therefore, testing is done in naturally aspirated form only is possible, but i am sure a few people already know that.

[fanta]

I take it there will be no provisions for lines and the AAC/FICD

Would fittings for lines be available?

[ISL33P]

there will be fittings for lines, as many as required, eg vacuum lines for fuel pressure regulator, boost controllers, wastegates etc. they are airline fittings that will most probably be located at the rear of the plenum and out of sighted, keeping the engine bay clean.

i would recommend the use of at least a chipped computer or something similar to a piggyback system or stand alone as the ultimate (if your budget allows).

there are no places to fit the aac/ficd.

these are the sacrifices that need to be made to take full advantage of the plenum.

sorry if this puts people off, but adding the facilities to have these standard components added would detract from the full benefits received from installing the plenum (it would also not make it look as good, something that needs to be considered).

anyway, do these components still work on your car ? as i have found that many, due to their age, no longer operate as per standard and have no real affect on the car's performance. please correct me if i am wrong.
