General induction discusssion aka mines better than yours

Re: me agen

It is apparent that torque gains are larger on the centos. You'd be looking at cutting half a second off 0 - 60 if that's what you want. Torque would move from about 60 to about 64 more than likely.

Re: me agen

No idea what spec that Punto was before the GSR was fitted.

newly cleaned bmc cda with a piped in air scoop with big fan blowing into it and still the gsr was loads better

On an otherwise stock 1242 motor? ?

Re: induction kit

and a crap remap that turned out to be same as a standard map

Re: induction kit

That has to be one optimistic rolling road. I do think the GSR is the best induction system out there, but everything else I take with a huge pinch of salt.

Re: induction kit

its not that big a gain

Re: induction kit

An 8 valve punto makes less than 60bhp in standard form. 85bhp is a better than 20 per cent gain. That's a huge increase from an intake system, much more what you'd expect from a decent exhaust, bigger TB, cam, manifold and inlet.

I have a Cinq with a Punto 60 motor, a good aftermarket exhaust and a GSR kit. It sure as hell isn't putting out anything like 85bhp.

i aint got 8v

Re: induction kit

Then the whole thread is pointless. No way can you extrapolate from 8v to 16v or vice versa. It's like comparing Binki to a guinea pig!

Re: induction kit

same sort of gains on the 8v as this, the gains is what he wanted to know

How dare you cast out my Novi' box like that.

Re: induction kit

Dave, was your CDA still running that setup with the induction system running over the top of the exhaust manifold? If so it's no wonder that the CDA is worse than the GSR, you're pumping serious amounts of heat into the inlet air which will deliver a noticeable performance reduction, especially on a rolling road.

On a side note, why are the two runs out of sync on the revs?

bit of editing on this thread guys but still makes sense(kinda)

that pipe so thick no heat effecting it and bonnet was open for that run.

revs hard to keep right with speedgear box

:yeahthat:

Lad of the other forum switched from the ebay shiney kit to a gsr felt a good improvement.

Personal opinion....GSR and novitec on par, but i never tested my novitec when my engine was tuned

How thick was the pipe and what was it made of?

If i was that pipe i wouldn't want to pass above the exhaust mani. seen mine glowing on the rollers with the fan on

 

[dave]

Re: induction kit

it had the cast manifold on at the time

 

[Brooky]

Yeah, but what was the pipe wall thickness/material?

 

[dave]

3mm alloy tapers at ends for smooth flow, the whole cda was where that pipe is when some dodgy bloke fitted it

 

[Brooky]

i recon 3mm wall thickness pipe will still suffer heat soak.

Was it silicon, carbon, ally, stainless, Ti
