Finally Heads are Done

[GOLDCYLON]

Its been forever but my heads finally came back from the full 36MM treatment. Cant wait to see what she will throw down with the 380 bottom end and Petes intake cams

Very nice!! Who did the porting?

[Paul Workman]

You will be surprised.....hang on to your hat :D
The wait is definitely worth it ;)

It is just super fun driving a ZR-1 with 500 flywheel horsepower :p

Dittos!

Nothing like a bunch of hp to turn what appears to be a "smooth" country blacktop into a friggin Lasagna noodle!!

[GOLDCYLON]

Very nice!! Who did the porting?

Local shop here in Arizona/ Friend of my son. It was a as I get to it after 5pm arrangement. Entirely by hand. He will be doing my other set of heads as well.

I hope so the target or my target was NLT than 450 to the rear. Most folks have told me that estimate is way low

You better get that POS back on the road, weather is perfect
Lets ROLL

Concur its been WAY.... too long Phil need to pick up those jack attachments as well :)

Will get to try out my Targa bar if it gets done before April

[oricale]

Hey, what is the average price to go from a 33mm to a 36mm and do you have to port anything else to match???

[GOLDCYLON]

The Average price is about $2500.00 that is not what I paid. The Plenum and the Injector housings were already done from previous work.

IMHO yes or else you won’t get optimal flow which is what you are looking for.

Very very nice :dancing

I think all ZR-1's should have this done.

Concur im thinking 50HP easy with the heads and new intake cams easy.

[sammy]

wow very nice indeed . can hardly wait to see what she does . who is going to tune it for you when she is done ?

[GOLDCYLON]

It depends if it good I will leave it or Corey's. Dom and I will work on it to get it real close first. GC

Sweet GC - nice job!

New LT5 porting guys......
Make sure you clean out all the oil passages very well. Not sure if they taped any of the heads oil galley holes up before porting.
Just saying... Be Safe.

They look good :dancing

[VetteMed]

Daryll, that looks GREAT! I'm jealous! :)

What will the mods be when you finish? Is it a 350 ci or...?

P.

380 bottom end
Full port 36MM top and now heads
Petes intake cams
Jeal long tubes with RT hiflow cats and corsas
ATI Super Balancer
Coplan open air blaster
Was going to install fidanza but David and the ZFDoc said for a daily driver ahhh no

[LGAFF]

I noticed no difference with the fidanza

[Paul Workman]

Far as driving in traffic goes, using the Fidanza vs. stock dual mass... I initially noticed just a little (teansy) difference in the necessary throttle and clutch let-out, the first drive or two. Now, it is assimilated, and innocueous.

That said, I do like the snappy accelleration. And, if one is considering a 4.10 gear, the reduced rotating mass would make even more sense, I guess.

I like mine...a lot. No plans to return to stock FW.

YMMV

[WB9MCW]

Fidanza's Rule -- Just have to get use to the dreaded "gear rattle".

Having a nice ceramic clutch from Carolina Clutch helps a lot as well IMO.

I feel the same, I enjoy mine and wouldn't go back. :saluting:

Given where stock displacement motors are registering with just porting,
I would agree 450rwhp is probably low when factoring in an additional 30ci. Will you be datalogging and using a WB?

Pardon me while I intrude on your post---
How bad is the gear rattle. Will I always think something is about to blow apart?:handshak:
:usa:

[LGAFF]

I don't notice it, its probably only audible to those sissies that also need 10 layers of quiet mat and exhaust mods to silence "the drone"

Go buy a damn Prius if you want quiet.....:saluting:

I get no gear rattle in cruise, and idle can be mitigated with proper tuning.
If it gets louder at idle, its after a long run when trans fluid is hot. Also using the right trans fluid helps.
I use the BMW Castrol 10W-60.

[efnfast]

Thanks Guys, nice. It's on the listt for someday.

Havent decided yet

with Pete's cams.....

490/430-35 rwhp/rwtq.

I agree w/ Dom (and don't think that doesn't worry me! :p)

That said, speaking of trans rattle, it wasn't always so. After the "500" package was complete, including the Fidanza, Marc upped the idle to 750 rpm. That helped. But, the biggest bang was the new injectors (Accels) (My injectors had been replaced at the time I bought the car, but apparently with NOS (aka same ol sh*t) injectors. It didn't show up until Marc was putting the tune on the new mods, except for the rattle - that I figured was "normal" for a Fidanza. Not so! ) Oh, and I run the Castrol synthetic as well. The combo of idle, injectors operating at 100%, and trans oil (especially when it's cold) and there's NO rattle.

Y'all be the judge: Here's mine idling on a cold (windy) day. Granted it is running stock cams - i.e., Pete's cams might be a bit differerent, I'm guessing.

Ok fellers on the topic of Fidanza

Should I or Not?

Lee drone vs exhaust note are two seperate animals. Corsa solved the drone issue for our cars. When I replace my carpet the Dynamat is going in as well its just a smart mod. :handshak:

As to a Prius, Not in my lifetime lol

Stocker hold's good to 540-550 rwhp. I don't like the Fidanza. But then again I don't like Corsa either. I like redheads....... it's just one of those thing's D. Save your money and install a stocker.

My Stocker is holding around 620 rwhp! Of course the clutch isn't stock...

After having to deal with tinnitus like symptoms since Oct.. I will gladly use Corsa to eliminate the drone. The low pitched drone/ noises would really irritate my ears especially with the Tinnitus symptoms

I do like the sound of Pete's and the rest of the guys Exhaust systems, but due to my ear issues I have been having, I am not about to change it and regret the drone.. or risk having permanent damage to my ears..

Have listen. starts @23 second mark.

[WB9MCW]

Yep that is the dreaded rattle alright - just a soon as you let off the clutch it starts.

No doubt you have to just put a deaf ear to it all and just accept that it is what it is.

Now I see some of you have made it much better with the tune-new injectors and different tranny oil.

So I guess that you can make it better with a bit o work and fluid choice. This is good indeed.

How about a vid with good sound from one of you who have achieved this goal so we can have a listen to your tamed rattle beast.

[tomtom72]

:mrgreen: I'll bet you look just like that!:hello:

Way to be Daryll! Use her in good health!

I had the rattle on my 89 with the Fidanza flywheel and even being a blck tag it did not sound as loud as Polo-1's video. The rattle on my 89 was more subtle then that

[XfireZ51]

This is a vid of my ZR idling after ported heads and Pete intake cams installed. Near end of vid I place the camera on the plenum to illustrate vibration at idle.
I did quite a bit of additional tuning after this which is now incorporated in the tune I sent to GC. We'll see how it works. BTW, idle here is at 750-825rpm.

[Polo-1]

I should say that's a 402 with SCG stage 2 intakes and 1 exhuast cams. With a little cam the motor start to make the tranny rattle...

[WB9MCW]

Wow that is really impressive - no rattle at all -- you were not kidding about solving the issue!

Amazing to me that a tune, injectors and a tranny oil change can make the difference.

Like they say >> Hearing is Believing. And in this case seeing as well.

So no idle rattle now -- How about the rut-rut-rut when lugging 1st or 2nd gear under low rpm? Was this improved as well?

I remember the first time I heard the rattle, I thought I spun a bearing.

Rattle will appear in idle after long hot run which indicates trans fluid thinning.
No rattle in any gear at any point.
