4agze tope End

[Koffee-Black]

Hey guys,

Discussion in the AW11 thread, but thought id make it more public.

Has anyone got a dyno shot of their 4agze??

As i was saying in that thread, after 5000k, it is SHIT! Kingmick has assured me that its the nature of the agze.

Now, what can I do to add more? Gun has suggest valves, cams and ecu, but am i better off spending that on a turbo conversion? I actually live the low/mid range of the gze, but only if it had more topend!! GRRR

Ok that was mean...

I'm pretty sure I was getting a little belt slip on that run, I can't find the 130kW one.

It still runs out of top end big time on the track though.

I'll dig up some graphs some day soon, though from memory, peak torque was at about 3300 and peak power at 6800 or so. Power was fairly flat from 6-7 and seemed to be dropping slightly by my fuel cut at 7. (all that is with aftermarket ECU).

I feel sometimes that the great midrange makes the topend feel not as impressive as it is.

Thanks Guys!

Ben, what boost does yours run?? Id love to make that power! How do I?? hahah

Ghetto, one day, i may go turbo son..one day! haha

id be interested to know the mods that you have ben

[Ben Wilson]

It's a standard bottom end with some mild head porting and standard cams. It's got a custom inlet setup (including handmade manifold), NEVO pulley, extractors and a Haltech. It's got a top mount ARC intercooler. It's also running mapped water injection before the supercharger.

It was still only getting 10-11psi or so.

It feels great on the road, but on the track it really feels soft....

wet shot of n2o not an option Koffee-Black?

[Koffee-Black]

hahaha naa, no nos man!

Thanks Ben.

The inlet manifold on the GZE is absolutely crap. Some moderate grinding to straighten it up as much is possible is a good start, a custom one is better.

Unfortunately to fit most of the available manifolds the supercharger has to be lowered or removed.

A 20V head (with throttles) will just clear the supercharger and is a fairly cheap upgrade.

FWIW, this is what my manifold looks like:

ive always found the top end softens up a little but not so much that id call it *bad* per say. mine has a custom 180mm pulley, exhaust, stock computer, stock ic.

i think its the great midrange making the top end look poor.

[Koffee-Black]

Maybe your right toof, but then I havent really driven any other sc cars. Min has headers, cat back, and a bigger pulley.

Ben that IM looks like it frees things up alot, where do I get one from?? haha

Grab a welder, a bunch of exhaust pipe and go for it

[Koffee-Black]

hmm...i dont have a welder...but I do have a soldering iron!
