Exhaust manifold / system

[Spudder16v]

Hello all, new to all the forum type stuff, so forgive my incompetence! I'm looking for a manifold first and foremost, to suit a sud, running a 16v with inboard brakes, but will consider a full system, I'm located in Chesterfield many thanks...

[Sud 145]

Welcome. An admin will be along shortly extolling the benefits of a "Shrewbeedoobeedoo" system. Trust him he's an Alfaholic.

[JetJackson]

I may have one. I will check.

[Spudder16v]

Ha! I'd read about the shroobedoobedoo system when he was designing/ working on it with on another forum, but that was 5 yrs ago....I assume he's perfected every requirement by now?! Look forward to hearing more....

[Spudder16v]

Jet, sound, let me know more details and pricing etc....cheers

Hi all

a 16v with inboards is rare mix, but we prefer to custom make them on the car anyway, that way we know its a perfect fit and the best it can be for that particular car.

and you're in luck big time, you're only 30 mile up the road!


give me a holla whenever you'd like to discuss it any further.

[Spudder16v]

Hmmm, the recipe worked for me in my last sud (15 yrs ago, ish...in fact, the last time the engine was run...) and unfortunately I bought springs for a sud rather than source the 33 stuff, so feel compelled to stick with the inboard for the time being... Hopefully I'll be chucking the motor in in the next month, and I've still got the bodged manifold I used previously to get the required 30 miles.... What sort of money am I looking at, and is there any ponies to be released with the shroobedoobedoo system? Cheers...

16v in a sud is fab, but i am totally biased of course, thats exactly my own mix currently

although i am outboard brakes so that i can have much lager anchors than stock, but i really like the inboard set up actually, the principals are actually very good in my opinion, and there are some upgrade options that do make them excellent once more too, but we digress, exhausts.

Money wise you are currently looking at £500 for a custom made performance manifold in our nominal design. Its a price we've held for coming up to 5 years now and probably the last year we will do so.

Its roughly the same price as the CSC which is poor and very unreliably available, and far far cheaper than the other bespoke manufacturers could offer, and we have heaps more experience with the Alfa boxer anyway.

But, rather than me making claims and statements about power hikes and torque numbers, which are of course immeasurably variable and different for every set up, i would prefer you to be convinced of our designs and work by the folk that have experienced themselves already.

Kev owned my 16v sud before me, and felt the benefits of our exhaust at Cadwell Park boxer meet, and there are numerous other owners and even some racers that are running our exhausts, and they will likely all be willing to share their experiences of it if you ask them nicely!


I'm not afraid of you doing some research on me buddy! lol!

[Spudder16v]

Yeah, it's seeing the csc currently on fleabay that made me do some research as to whether it would fit that made me read on another forum about the r+d you did about the benefits of a crossover manifold etc when you were in the designing stages, and yeah, it's most likely be the way I'll be headed with mine, unless a used manifold / system turns up meantime, did you not have a few practice runs?!!

[KevJTD]

on the sud 16V I did for track day use, now shrews, the difference was noted by the fact that before the manifold/system was fitted we could go from the hairpin to barn corner at cadwell and the choice would be hang onto 2nd or shift to third before turning in at barn, with the new exhaust system we were hitting the 7.2k limiter before turning in so had to snatch 3rd.
everything else was the same on the car, same tyre size (road tyres still although we ran slicks in the afternoon) no gearing change, no drastic weight loss. only difference was the full exhaust system.

[PETROLHEAD]

No practice runs I'm afraid, and nothing used that could be easily modified for you.

Might have been been different if you were already on outboard brakes, which is why i commented that it was an unusual mix to have the later motor but not have the later brakes with it.

Would the csc you've seen fit around this?

If its to fit a 16v motor with the correct flanges, sizing, spacing and routing it would be to fit a 33 series 3 or even a 145/146, which means it wouldn't necessarily have been designed to go round the inboard brakes i suspect?

Vice versa of course, if its an earlier design to fit 8v alfasud layout with inboard brakes it wont fit a 16v motor.

If its wrong you'd end up spending more money in the end having it all changed so be careful mate.

That said, if its the mild steel, croatia based one i just found on ebay, the primary headers are very short and the secondaries very long, so maybe they do all their routing before having to clear the inboards going back?

It looks as if it is sold, but, if you end up with something like that be very careful of using it on a lowered car, the crossover section can become very secondhand very quickly!

[Spudder16v]

Kev ,having binned a car (not a sud.. ) on that area of cadwell, that description speaks volumes! Cheers

[Spudder16v]

Shrew, trust me, I'd be outboard all day long if I'd still got the 33 that I used the motor from, but like I said, that was about 15 yrs ago... But at that time I thought the earlier 33 suspension was needed to keep the wheels within the arches, so didn't bother! When I've got the engine in and running (again...it's been on garage floor for waaaaaaayyyy too long...) I'll be most likely another recipient of your manifold, provided funds allow... I really need to move a car or 2 on!?! Anyone interested in a tax exempt spider?!!

[PETROLHEAD]

33 front legs, springs and hubs are cheap enough nowadays mate, John at Justsuds will have them in plentiful stock i reckon.

as for the Spider, i reckon you'd likely have some interest if you bung it in the Classifieds, i'll certainly push it for you wherever i can buddy.


Whenever you're ready, give me a holla and we'll sort you out no problem

[Spudder16v]

Yeah, I've bought a fair bit of stuff off John recently, unfortunately including the set of lowering springs for sud suspension, so don't really wanna waste those for a swap to 33 gear?
I'd think / hope that a manifold designed around the inboard brakes isn't going to lose a great deal (performance wise) and will allow me to swap to outboard in the future, as time allows for rerouting brake pipes and handbrake being moved to the rear etc etc....!
I'll get the spider in the classifieds as soon as I figure out how to upload photos ( definitely not brilliant with the whole technology thing!!) and cheers, will let you know when I'm ready bud..

[PETROLHEAD]

Yep, we'd route it round your inboards as it needs to now, and thats all you'd need for the future changes, without any fouling when you make any changes, other than a big wide wing sump maybe, they'd create a problem if you ever want one of those?

As for uploading pictures, its pretty straightforward, so long as the pictures you want are on the same pc,laptop etc, we don't do what a lot of other sites do and have you upload them to a 3rd party site like photobucket first and then create a link to it, oh no, we like it much simpler than that here!

I think i'll do a quick "how to" in the Site News and Info area, its there for everyone to see then eh
