I remember when they posted every dang week on that camshaft thread, where did it go? How close is Crawford to making a 300WHP Z? My money is burning such a huge damn hole in my pocket. I am ready and willing to pay FI prices for this pack!


Mainly because no FI currently tickles my fancy:
Vortech- meh, who doesn't have one? Also, boost and tuning problems etc.

GReddy - No thanks, I like my engine to...uh, work and stuff.

APS - Holy god, incredible kit, nice guys, great company, but the kit is pretty far on the expensive side and I dont really wanna add too much weight to the front of my car. And I dont want traction to be much of an Issue.

Procharger - uhhh, kind of rareish and obscure. Not much support, I dont like it, dont try to change my mind.

Tubonetics - almost NO HP made below 3K RPMs. Kit is cheap and easy to install.

APS single - I know nothing of this kit

Stillen - HAD IT ALREADY! Great kit, great support, great power. But I have already owned one, so the 'newness' is gone.

So yeah, I want the NA-est engine I can get my hands on without effing up the driving characteristics of the Z. If anyone can tell me who is making the most NA power and how, or the state of the supposed Crawford complete NA kit, that would be *****in'

 

At ZdayZ Doug was talking about trying a new set of cams in Vandy's car. He was also playing with a larger TB on his Z and was a little unsure about the ported heads that were on his car. They are still playing around, but at this point it takes more time and money since the easier mods have all been tackled. Not to mention the fact that he is trying to keep things emissions safe without requiring an additional piggyback control unit for tuning.

 

this is the hardest part.looking forward for the result patiently.

 

GY-Z - I love the Amuse kit.

But come on, If there are FI kits that pass emissions, then why are there no complete NA kits?

 

My car is apart at the moment receiving the new cam package. Specs will be released at a later time. After installed the car will be dynoed with current flashed ecu. From there additional tuning may be necessary. This is a cam only install . . . no headwork.

 

Its very hard to tune for N/A hp. Very time consuming and expensive for relatively small gains. Sure some monster cams with an idle @ 2 grand would make big power, but I cant exactly drive up to the emissions station with check engine lights and something that still shakes at that idle. Finding the happy medium is the goal.

 

so how far are you guys to making 300 wheel?

Are you researching as to why some of these cheap little spacers are making MORE power than an upper plenum? Have you considered doing a Kinetix-New Style plenum? It made 17 WHP at its best, and put lots of area under the curve.

Thoughts?

 

I might know by the end of the week.

Man, you are trying to get me in trouble here. I dont think I want to open up that can of worms. If you really want my response to that I will pm you.

 

what exactly do you mean by cheap little spacers? Sorry if this is a noob question.

 

AAM and Motordyne have created little plenum spacers than increase the volume of air your engine gets, much the same way a plenum does. These are cheap, and I saw a comparison between a spacer and a Crawford plenum, the spacer won, and I was in disbelief.

 

Im sure there are quite a few of us that would like to know aswell...

 

Ha! In TN you sure can (not in CA though... Man did I have fun with the smog techs back home )

As for the spacers, that's an interesting subject. Condsidering I don't yet own a Z, and still consider myself a n00b after much research, I'm going to take the risk of inserting foot -> mouth just for conversational purposes.

On other cars, such spacers have been titled "phenolic spacers" and while helping get a little more air to the motor, they also keep the intake manifold further from the heat source (thus delivering a cooler intake charge). Could any of the stated gains be attributed to the cooler intake manifolds? Just a thought

 

to be honest, +1
but please don't post anything you don't want too

 

Glad to hear an update.

BTW, the Kinetix-new-style-plenum can just be simply called an intake manifold. And it's too expensive for the gains IMHO. Any chance Crawford might come out with an intake manifold?

I don't think the spacers vs. upper plenum debate will ever end. Take a look at the F/I section and look for a thread about Dyno numbers. Numbers can be skewed, and numbers are ALREADY varied between runs (~5-10rwhp). Honestly, i'd go with an upper plenum if you are going for 300rwhp, if not, a plenum spacer would be fine. Also, I think it has more to do with increasing intake plenum displacement (agreeing with Charles and Sharif on that one) than front cylinders being starved for air. A few of their posts made sense to me, so i'm going to go with that opinion.

 

And again, I'd like to say that the Stillen is STILL the only Carb-Legal kit there is. Unless HKS is cool too.

 

VandyZ, do you think the 300 hp track engine would have hit 300 rwhp with your current setup or do you think it would still be in the same boat?

 

Hopefully we will see later.
