What inlet manifold

I am looking to upgrade my inlet manifold. I have seen ones from jabbasport , APR and JBS is there any other worth looking at ?

Anyone use one of the above and can give me some feedback.

I would like to get a larger trottle body at the same time is the R32 one the way to go ?

 

What spec are you running then. My understanding is the std manifold isn't really restrictive under 400bhp.

R32 TB is larger but once again not restrictive until you're running serious boost & power

 

Running about 430 but with a bit in reserve and have a nitrous system ready to be used next year so I would say up to 500 bhp.

 

have a browse here>> http://www.clubgti.com/forum/showthread.php?t=171919

300bhp cars gained significant power on those tests.
test car was smallport, smallport SEM manifold with 80mm t'body.
impressive gains vs stock intake

largeport gains will be higher to the limits of what the turbo can pump.
my own 007 mani, made me 32bhp bolt on on 485bhp

have a read thru my section on the SEM inlet manifold.
nice gains are to be had.

 

I like the look of the SEM one and you cant argue about the power gains but the throttle body is at the wrong side for me.

The only way I could make this work is to move the charge cooler which might not be a bad idea as it would shorten the pipe work.

 

Full race is the best off the shelf available.

Costs though.

 

Not really the case.

007 in those tests was, and SEM outflows 007. (waiting their test data)

 

A static flow bench test without the manifold attached to the head is not a great indicator of how it will perform in a dynamic situation.
A flowbench can't simulate the effects of wave actions either, Although they are less important in a FI engine.

Have a read of this and find some SAE reasearch papers on intake manifolds.

hiya

bench tests are an indication on port flow and balance.
agreed its not 1:1 correlation, but 007 & the new SEM will head the tables in flow and balanced flow abilities.

SEM is $825, Hypertune is >$1100

007 mani on my own motor gained a real 32bhp/22lbft bolt on from a previous dual plenum largeport manifold. Nice gains for bolt on. 007 worked well, SEM is designed by the same guy, flow modeled, and unlike the 007, is available for sale now.

Not saying Hypertune is'nt good, but its the most expensive and not the highest flowing, so I dont see how it can be deemed the "best" out there. One of the best... but best bang for buck it is'nt ever going to be.

and lest us not forget:

Which this is of course.

I have the flow models of the SEM if wanted.

I have posted dyno's of stock vs smallport SEM and the gains measured. Do you have any comparisons for the Hypertune? be interested to compare them..

 

Bill,

Please could you PM me an all in cost of the manifold (small port) with 80mm throttl body please.


Also how long is the delivery time.

Many thanks

Martyn

 

recommended is largeport one + transition gasket & 80mm throttle.
posted prices now in badger section.
*subject to ForEx*

I have 2 on their way to me now.. one for badgerwagen and one for stock. both largeport & 80mm throttle.
My 007 largeport with R32 t'body will be 4-sale once SEM arrives and is fitted.

 

Bill I have a AUM engine will the largeport one fit ?

I am very interested If you can get back to me tomorrow with the the above info I will give you a definate answer.

Its a 90% Yes if it fits

 

The inclusion of a phenolic transition insulator gasket is what allows the largeport mani to fit your head... and allows you future porting plans.

Mine are supposed to be on their way this next week.

 

Ok Bill if you are 100% positive it will fit I will have it.

How would you like me to pay ?

 

Bill,

I have just been reading on another forum that bigger injectors need so spacers .

I currrntly run 630cc one will I need them ?

 

depends on the injectors.. spacers can be provided no worries if req'd

 

Ok thanks Bill.

Are you sure you dont want me to pay a deposit for the manifold ?

 

you can if you want to.. bell me tomoz

 

Bill is changing the inlet manifold a straight forward job ?

 

bolt on physicaly. some hoses to connect.. probably good idea to get a few lengths of silicon hose from forge (or me) so all vac lines can be changed whilst doing it. some of the hoses are getting crusty. If changing from one side to t'other t'body wise, you will also need to extend the wiring to the throttle on the lhs (of car)
