Edelbrock heads

[peasea]

I bought myself a pair of Edelbrock Performer RPM heads a while back, got a Comp cams V-Thunder cam and a bunch of other shit for my Evo. Question is; has anyone else run these heads and what was the outcome? I'm not expecting (nor do I want) big HP, I just want some extra torque, which these heads will (should) provide. However, I like longevity in my bike, so if anyone has these heads....how are they holding up?

[rok-the-boat]

A friend of mine put these on his bike, plus piston and mild cam, and it made quite a difference. The stock heads are crap. You will notice the difference. And if you really want to let the engine breathe easy, get a Thunderheader - there is no better pipe to get extra low down and up omph outta an Evo - it really is an amazing pipe. Bog standard 1340s put out about 55hp. With the above, set up right, you should be over 80 or even 90hp - a very torquey 90hp. It's the easiest way to get more - you can't safely overbore 1990 engines as the cases are too weak.

By the way, mine was an FXR too, or rather, a 1990 FXLR. I have a few bits if you're interested - selling various parts on TM right now. If you're local, could even help you fix it up. I like FXRs ...

Keep me posted eh?

Exacerly, I was wondering how a 21 studder was going to fit on a hardley ableson! :dodge:

Scummy, I think you had the answer.........

With my old eyes it looked like a 24 studder - a 8BA late model one too...

Hogan twin-plug heads were good - but blardy hard to get an' spensive too.
S'cuse the writting but a few bourbons to celebrate my being voted in as pres of the Hot Rod club has muffled my brains a tad.

Yeah? Which club would that be?

I was thinking more about the salt-racing engine. Now THERE'S a flatty.

Pleased to be able to contribute (even if I can't count)

Pic? If you mean the profile one, it was the Kaipara 200 last year coming off Muriwai. Living proof that I didn't fall off at every opportunity!


Back to the flatties.....there used to be locally made alloy heads as well, not twin spark and, as I recall, fairly porous castings but Nick Liefting always seemed to have a few lying around at the Greenlane speed shop in the late 70's. Unfortunately, being incredibly fervent smallblock fans we paid no attention to those old bits of crap......:sick:

Great wee things those small blocks. I screwed one together that runs consistent 7's, blown on alcohol.

Garth Hogan's old man used to meke them and I spoke to Garth last year before they set off to Bonneville. He's got solid billet heads now, really thick mothers that act like a heat sink.

Delta Rod & Custom Club

I've heard of them.

I used to be into the hotrod scene for nigh on 20 yrs, did 3 yrs as club pres in my one.
Had some decent cars too, raced at Thunderpark etc...........now its all bikes for me, and love it heaps more.

Thunderpark! Geez, that brings back memories....we trekked up from Welly all the time, then I moved to Hastings in '81. I had a good time there, great people.

When Hogan ran his 5's I was on the startline for one night and later that week I was at the top end when he ran the mph record. Got a rush I can tell you; I haven't been the same since and it's not something you can explain to people. A nitro-fuelled car has to be experienced.

Was a great place. I raced at the very last meeting before it shut which was a lame version of NZ fastest muscle car, back, prob about 96?

We used to go to the finish line and watch Hogan and the wild bunch fly past.
We used to have a wee puff of some stuff that kinda made it more interesting at that speed going by!:yes:

I get over to OZ occasionally to the Winternats and watch up to 8 fuellers racing....awesome!

Down here in redneck country we use to have Car Club type 1/4 mile sprint, no OSH etc back in the late 60's/early70's.
The drags were on a side street that was only sealed in the middle 1/3, the 1/3 each side was still gravel.
The 'safety-line' was the edge of the seal, for safety reasons you had to stand on the gravel, if you stood on the edge of the seal the race was stopped until everybody was off the seal.
All sorts turned up, Customlines, Zephyrs, Jags, Triumphs, T-buckets etc - 'run what ya brung' was the order of the day.

Sorry about the hi-jack, overtaken by a wave of nostalgia.....

Yeah, ditto, take in the Wintersun while you're at it. I love the pits at Willowbank, big-dollar billet parts everywhere. garth said that the US Nationals at Indy was something everyone should do before they die. Might try that one day.........

All good. They're aspects of the Mainland that we love, so much of that attitude still exists. It's as if OSH hasn't figured out how to get across Cook Strait and if they did they'd still be ignored. Long may that remain the case. Common sense prevails, you don't need regulations for that.

(In the mid seventies I had a MkIII Z-car with Webers, man was I cool......)

We're going to the Winternats at Willowbank next year.
We usually book seats in the VIP stand right on the start line, so the seats and VIP treatment are all reserved for the 3 days.
Literally metres from fuellers burning out!
Ear splitting action and I refuse to wear ear plugs!

Yeah me too.

On our HB weekly rides I ride past where Thunderpark used to be to get to our meeting place.
Just grapes now, but you can still see the return rd.
Put in over 1000 passes down there in a variety of yanks and rods.........ahhh nostalgia eh.

Only ever took one bike down there, my old VMax.

No wuckers, it's always interesting to hear about where others have been, what they've got up to etc. We're obviously on similar wavelengths.

So they DID put it into grapes, huh? Was TP on SH50 or something? There was a hill opposite, can't recall the name but at the base of it was the Deerstalkers Club. Man, got trashed there a few times, and at the Angus, and the Mayfair (good bands there, saw Midge live, rockin' etc).

Did you ever go to a night club called 'Bananas' in Napier? What a sound system!!!! AC/DC's Back in Black had just been released and it was a total blast up there! I won't say what we did at places like the Frimley Lodge, The Apple Motor Inn and others, bloody funny at the time tho, watching the manager netting the pooh in the pool. Most unsavoury.

Delta Rod & Custom Club

How many years have they been running? Donkeys?

Just got back from helping a mate set up his silver Cobra at the Telstra Events Centre in Manakau. national Hot Rod Show, don't you know.........

Bloody high standard out there, top rods, street machines and muscle cars. Unreal quality.

Yep, is a vineyard called Balthazaar, on the road from Fernhill to HW50 just across from the deerstalkers hall.
I believe the track sold for about 400k for all the land over 20 acres. And only not long over 10 yrs ago, amazing when you consider that most houses are over that, and also due to theb track being the best surface and flatest in the land........no drag racing person brought it.

I lived not far from the Mayfair, with its swamp like carpet, squeelchy from all the fluids spilt each night over the years.

As a side note, in the current Hotrod mag, the feature on the red 32 coupe, my mate was the builder of that originally.......well he owned it, I built a lot of it for him, including the engine and finished it all off for cert etc.

Just had our 30th Anniversary run this year, a lot of founding members still in the club.

As it happens I've just come back from Southland Rodders 40th this weekend, good turnout with 50+ rods/street machines.

Got a report for NZPH?

i have Edelbrock heads an EV27 cam , Wiseco forged flat top pistons , Jims lifters a Mikuni HSR42 carb with a hypercharger aircleaner , a crane single fire ignition and a V&H Pro pipe on my 1988 fxrs lowrider , she goes like a cut cat haven't put her on the dyno yet but would imagine and easy 80 hp

only thing is you are either gonna have to block off the head breathers or modify your rocker boxes to use them , i did the modification but she tends to blow a little bit of oil out the aircleaner but i thought that less crankcase pressure is better so why not , have had the moter together now for 11000km and no problems other than the afor mentioned breather problem , on our SI trip in feb i was getting around the 50mpg so i am very happy , one thing i was told by Doug Hayes properly warm your engine before riding or you will crack your heads:rockon:

Doug's no fool, we stayed the night at his place the other week, on the bourbon, talked a whole load of bollocks but a good night anyway. He and Erin are great people.

My breather comes from the back of the crankcase, not the heads. I used to get a few drips from the stock air filter deal so switched to a teardrop arrangement (much like the S&S setup) and nothing changed. I then re-routed the tube to a seperate breather filter, which I mounted under the oil tank on the PRIMARY side and voila! No more drips and it's been like that for about fifteen thousand k's. Not a drop! I live in hope that the current system will suffice when I switch heads.

I don't doubt your 80hp claim with your combination; why not get Doug's boys to check it out on the dyno at R&S?

PS: Warm everything up first, from your bike to your missus.

[bernardf]

i will have to get me a catch tank at some stage but it isn't a major
i find that the missus warms up quick on the back of the bike
will have to put the bike on the dyno one of these days , would definately go to R&S as opposed to the crowd in Auckland , them Hamiltonions are a friendly bunch and helpful too
