manifold spacer on ecotec -- WOW

**VS 666** · 03-09-2010, 01:20 PM

My mate and I put this into my car yesterday ... He is not mechanically minded at all and I can name engine parts but thats as far as it goes... his first words were "how can this 12mm piece of wood make your car better?" and at that point to be honest I had no idea and was hoping it wasnt going to be a dissapointment.

After 30 mins of following the very clear instructions on the website (most of which was being super careful with the gasket goo) It was in...

The wait for the goo to dry was a killer... I was dying to see if it made a difference...

I hopped into the car after an hour with my mate and drove off... got onto a highway... going around 40kph I planted and the auto responded with 1st gear... it felt like a bit more power but I was a little saddened and thought oh well maybe this was a waste...

I pulled up to the lights shortly after... this is where my mate was chanting i told you so bla bla bla..

light turned green I almost put a hole in the firewall with the stomp on the pedal...

It launched almost immediately (unlike previous ecotec lag) and roared... it was as if it was pulling between 4-5k through the entire rev range...

I cant get over the difference in lower revs... I admit that higher revs are somewhat similar to standard but the fact that it spends less time between 2-4k provides much quicker overall accelleration.

Thanks to steve for all your help

12mm or 25mm?

This and a plenum spacer is next on the cards for me.

EDIT: Just re-read your post... you said 12mm...lol

**VS 666** · 03-09-2010, 03:37 PM

yeah plenum spacer is next on my hit list... but whilst dismantling the plenum i noticed some gnarly cracks so im going to replace that before I make my next purchase...

25 mm manifold needs some extra hosing (as noted on his instructions) and I wanted my engine cover to fit nicely so i chose the 12mm

**old mate** · 03-09-2010, 05:59 PM

yeah they're supposed to be a good thing, i'm fitting one to a mates vy wagon in the next few weeks. i want to see the difference (25mm).

definite increase in low - mid range torque though due to the longer intake runners.

I love my 25mm manifold insulator. In fact, I'll buy a 12mm plenum spacer right now...

The kit from MACE comes with everything you need, including the hose extensions if you get the 25mm, and gasket goo. I did it in around 30mins, having never taken anything much more than the throttle body off before. The instructions are perfect

**Trayner** · 03-09-2010, 07:16 PM

Yep thats it.

**Trayner** · 03-09-2010, 07:26 PM

From what they recommended to me, if you don't want forced induction down the track, 25mm manifold and 12mm plenum spacer (which I am getting when MACE comes online), and I think the engine cover still fits on. It definately does without the plenum spacer anyway.

FI is the opposite, 12mm manifold and 25mm plenum....because of science or magic or something

well looks like ill have to get the 12mm manifold and 25mm plenum , cos when im of the P's the supercharger is going on :P

**sedgewik** · 03-09-2010, 08:37 PM

what are you selling a free lunch?

**immortality** · 04-09-2010, 02:57 PM

if your intending to get the 25mm plenum spacer don't fit it until you have fitted the supercharger otherwise it will reduce your throttle response

as mentioned, 12mm plenum spacer and 25mm manifold insulator is the best combination for atmo set-ups, chuck on a large TB to finish it off nicely

**MACE** · 04-09-2010, 07:49 PM

Glad to hear your happy with the insulator VS 666

We got some other feedback on this family of products recently on a turbo VT V6. Before the 12mm plenum spacer and 12mm manifold insulator the best time she did was a 10.20@ 140.2 mph. After they were fitted that dropped down to 9.82@142mph (best MPH of the day was 142.99)!

Here is clip of this beast in auction which is a MUST watch as the car is quite a handful on the track LOL

Cheers
Steve
