hi i am having a miltec full stainless and manifold with induction kit and roll and road fitted soon on my valver i was wondering if anyone has done similar and wot kind of bhp gains am i looking at?
-
what induction kit is that?
i guess 156.3 bhp :huh:
-
you should get a 8v, has beter torque lower down....
*runs..... :laugh:
-
right, im getting a diesel :cool:
-
having a rolling road fitted to you car??? genius.
exhaust = 6-10hp
Filter = 1-2hp (if that)
-
^ lmao
-
yeah if only sorry i ment getting it roll and roaded so it is set up properly is the 156.3 thing what u got or just a big guess :tongue: it is a pipercross induction. also do u guys think it is worth getting an induction kit or just gettin a filter and drillin the airbox
-
doesn't really matter what you do filter wise, all they both do is make a noise. Induction filters add 1-2hp tops, and that is proven. By myself as well as the manufacturers. If the filter did so much do you not think they would of added one as standard? It only costs a few quid more than a panel filter anyhow.
-
156.3 is just a random number :laugh:
i would guess at 150 to 160 if you get it all setup properly
-
yeah big boys toys is doing it for me so hope it should be set up alrigjt. cheers for the info anyways
-
also depends on the mileage on your car. anything with around 100-125k on it (depending on how hard a life its had) u'll be starting to lose compression as the rings need replaced
in honesty i reckon u'd be lucky to see 5-7bhp increase. an original vag 16v system is just as well flowed as any stainless system
and unless the manifold was portmatched to ur head it'll do naff all except make a lot more noise!
also, at the rolling road id make sure u have another 16v or similar along that u can match the rollin road results
thats why actual group rolling road days are good. cause u get a wide spread of cars there and that way u can see just how accurate the rolling road is!
-
The general rule for filter + exhaust is 10% increase. Not that much so don't spend big money.
Sport filters are the easiest mod, what everyone forgets to mention is they increase performance more mid range than top, so you don't get big overall increases, but you will get a nice more responsive engine.
Manufacturers don't often use performance filters because of the noise levels, its as simple as that.
-
so do u suggest not getting the manifold and just getting the zorst?
-
otherway round if anything, the manifold will do more than the exhaust i would have thought, especially with a bit of heatwrap. plus bonus of tubular manifold you save loads of weight from the front of the car.

:smiley: :smiley: what he said.
-
so what do you guys suggest i get put in? my long term plans for when the engine finally dies(hopefully never :undecided:) will) are to get DD to put a 2.0 16v engine in it. do u think its worth payin 500 for manifold and zorst?
-
it is alot of cash but if you're planning bigger power upgrades in the future then the manifold/exhaust won't need up grading in the future. make sure you get heavy duty engine mounts especially the front one, if not a solid one, as stainless manifolds are more brittle than mild steel and if your engine is moving around alot it'll crack at the welds.
-
how much would i be looking for heavy duty engine mounts
-
solid one from me will cost you £75 inc postage, a vibratechnics heavy duty mount will cost about £115?
the solid ones do increase the vibration in the car on tickover but nothing thats gonna bother you.
-
People get blinded views from fitting performance airfilter & Exhaust from the likes of Maxpower and Fastcar magazines!
The truth is, yeah you will get a power increase of about 5bhp depending on engine condition.
Before you get an Exhaust and airfilter it may be helpful to read a book or go on a website to learn about back pressure of a car.
You may of noticed that Rally Cars dont have Big Bore tailpipes cause they need to hold back gases to make sure they burn exactly on time in the combustion chamber.
Otherwise whats the point in letting unburn fuel out back of exhaust?
-
good point so what do you people suggest? i am confused atm some people saying get one other not anyone got the + and - of getting a zorst and manifold! atm doesnt look like its worth spendin the money
-
If you want performance then get Airfilter, Cam, ECU remap, and Exhaust Manifold. This combination of bits will see you good performance if set-up correctly. Trouble is, people do one thing to their engine but not others. Stainless Steel Exhausts are great for noise and lifetime garantee as long as you stay same size bore.
VW Factory made the bore that size for a reason! :rolleyes:
-
So fitting a sports exhaust won't help performance?
-
Yeah, it will release a couple of ponies.
But its all mainly for noise! Like i said, they help gases escape more quickly which is ideal for turbo or Supercharged cars, but Normally aspirated engines need to hold back pressure back. :smiley:
-
Fitting a sports exhaust and filter certainly made my vr6 more reponsive, and that is a naturally aspirated engine.
-
Yeah, its made all my cars more responsive too.
With your VR6, the Airfilter sucks in more air, so the air/flow meter says oohh, need more fuel, so it richens the mixture, thats why its more responsive. But it cant ignite the fuel quick enuf so looses a bit of unburnt fuel out exhaust.
Thats on an exadurated scale! :laugh:
-
All engines will lose a bit of unburnt fuel out the exhaust. On my vr6 it is very minimal judging by the emissions on the last MOT.
On road cars, most will benefit from a sports exhaust and a sports filter. This is because manufacturers want to keep noise levels down, but this also hinders performance.
I don't think you can really compare a road car to a rally car, as they are highly tuned, and any alteration could prove critical. On a road car this is not as important.
From my own experiences, a k&n and a drilled box proved to be the best mod on my vr6, better than the exhaust.
This is not because i got huge overall gains, but because i got a much more responsive car.
With a stock filter and a standard airbox, the car did very little below 4000rpm, but with a k&n and a drilled box, the car started to pull well at about 2000rpm.
Personally i have had 2 16v's and a vr6, this has proved the case with all the cars.
The better a road car can breathe, the more performance, its that simple.
-
exhausts will probably be most effectve when the head is breathing better than standard :huh:
-
Thats what i was saying earlier, to get the most from the engine you cant just stick on a air filter and exhaust, you need to fit high lift Cam, and get Head port and polished. That way you get nice delivery of air / fuel. :smiley:
-
calm down i dint meen this to get heated :laugh:
-
Agreed. However i was just pointing out its not always about overall gains, if you can boost the range performance of engine it can be pleasure to drive :laugh:
-
yeah thanks for the info but it may have been a nit unsed for me since im now considering getting storm developments to do a vr6 conversion :laugh:
-
How about turbo or superchargeR?
if you dont agree just explain me why?
thanks
Pedro
-
the noise i went out in the demo car and damn was it good + its f**kin fast and i dont really want a turbo too much£Â£ and i dont like em supercharger maybe but tbh i like the look speed and sound of the vr6 atm
