Hi guys,
sorry if this has been done to death (I am sure it has). I have done a search but not had a lot of time due to internet restrictions at work. I have a X16XE equipped Corsa Sport and want to pep it up a bit. I have seen these three manifolds which I believe need software flashes or re-chipping to make work.
Which of the three is considered the best to get. NOT just in terms of BHP/LB/Ft gains but overall driveability. I am not interested in peak hp if it means torque curve is knackered. I would rather have a compromise of both.
My car has 85K on it, FSH and no known faults. I will fit a four branch tubular and stainless system at some point. Car currently has a Pipercross induction kit, which does typical induction kit things. Will sort that out soon enough.
Thanks in advance for your time and advice.
Davey

Lexmaul gives gains across the rev range and is easier to fit. But, they are hard to get hold if iirc. Wheras the mantzel/dbilas are peaky and readily available. Great fun, but a bit of a pain when you want power. You don't need a re-map to get them to work, they offer great gains on standard maps. But, to get the best a raised rev limit and re-map will give you the best out of it.
Oh yeah, ignore that 20BHP bullshit that you hear. No way.

Yeah I did think that was optomistic at best. I have been tinkering with Golfs and GTE Valvers for donkeys so I know it is aiming a little high at best. However, even a ten bhp/ten lb/ft gain across a wide range will make a noticeable difference. It is more driveability than anything else that I want.
So Lexmaul is the one to look for then. I may go new if need be. Will get exhaust done first I think as this won't cause any hiccups.

The lexmaul is meant to give an increase in torque aswell. Whereas the mantzel gives fuck all torque i found.

Not true about loosing torque at the bottom end when you have fitted a mantzel.
This is my before and after.
Notice the lower and top end there is more torque but in the middle it's down a little. It does that coz it's overfueling, but a remap would cure that.

Mine only made an extra 2lb/ft of torque with a mantzel fitted

Does anyone have a web address for Lexmaul or do they only deal via channel partners? I did a search on Google and the like and no joy?
Thanks again for thoughts peeps. Much appreciated.

Does anyone have a piccy of their Corsa with a Lexmaul fitted. It looks so much different to the others. 415EUR too with our exchange rate is worth a punt new too!

Is that on a 1600 16v?

And what did the torque look like?
You could make the max torque at say 4k rpm, but then crap torque everywhere else.
OR you could still make max torque at similar revs, but hold good torque throughout the revs.
Its not all about peak figures.

that graph doesnt seem right 
basicaly +20bhp is aload of crap
but these inlet make a massive difference to the way the engine performs
iv have the lexmaul, and mantzel, lexmaul gives nice power from 4k to 6k, where as the mantzel realy kicks at 5k to the limiter, if you love reving an engine, then the manztel is for you, but to make the most out of it you will require a raised rev limit
the mantzel holds the torque in the higher revs where as the lexmaul starts to die, the manztel just pulls

lexmaul mate.. you wont regret,, ran mine on a standard map for ages and it was fine.. even better with a remap though..
the power increase was insane over standard inlet on standard map...
mild turbo like kick

Lexmaul it is, my German is rough as after some 10years of being out of school!!! Can you get any software to translate the site?! LOL. I see the unit I want is like £286 new from Lexmaul. Can't sniff at that!

You can't. Considering a new mantzel from germany is about £500

HOW MUCH?!!! So that!
I only gave 1200 notes for the car with tax and on it. I like it, but it needs to be VFM still. I can shell out £300 no probs and with my new flywheel it'll chirp along nicely. Re-map I can do at a later date as the car is not a daily drive.

Yep, inlet, lightened flywheel, different final drive and an exhaust system and re-map, it will go quite well.

had both a lexmaul and a mantzel, unless you plan to raise the rev limit go for the lexmaul

No plan on upping limit. Standard cams in place and I don't want to disturb bottom end by slapping ARPs in at this stage. I'll do the SBD Rollers as I like to drive it entusiastically and often. Lexmaul looks neat too I think. Right. Decided. Many thanks chaps, will stick some extra hours in and buy me one of those little beasties.
Incidentally, which final drive do you recommend, it is for road use, so I don't want to up the revs at motorway speeds if I am honest. I'd prefer to sink money into having my interior how I want it and just little touches really to make it mine without making it unsellable.

Thanks Dean. Handy pointers. I don't think i will be going that far with it at this stage, although it is food for thought should I up the ante a little.
