Is that a 2300 Atomic?

[mechatron]

My 2 cents: I had Chev's whack a HTV1900 on my VYII SS Wagon near on 2 years ago now ............. wow, that long already ........... started with all the usual bolt on's and some suspension work. Was nice for a short time but REALLY wanted some more ........ the difference from bolt on's to PD blower (6psi) was like having sex as 16 year old for the first time !!!!!!!!!!!!!!!!!!! BLEW my mind!!!!

Just like being 16 though, I soon realized that I just couldn't keep my hand(s) off it ............... *evil grin* and soon upgraded to 9psi - that kept me happy for about a year until I needed just a 'little' more and went down the blower cam route .............. 350rwkw/715nm - A year later, I STILL love getting in it! It cruises like OEM but when that angry pedal goes down ............. Yeah Baby!!

Do I regret it! - Shit NO! - Don't ask my wife the same question though ...............

DO be mindful though, as some (including myself) have found out, once you get up around the 300+ rwkw mark, shit starts to break/wear more often than it used to (especially if it is a daily - I'm already a couple of A4 builds down... and honestly don't think I drive it like I stole it...); Also, the quicker you 'can' make it go forwards, means you really need to have an 'appropriate' ability to 'stop' it just as quickly (at least that was my thinking anyway) .............. again, do I regret 'any' of it ............... nope, in my mind it all made sense and continues to put a BIG smile on my face every time I drive it (even those moments AND sounds that make you 'cringe' are soon replaced when you give that right foot a 'little' squirt ........... YES, PD blowers all day, every day!!)

If you've got the coin and the inclination, then 'Just Do It'...... *wink* ........... I don't think you will regret it.

Thanks man, great post

awesome thread .

I am about to supercharge my SSV (magnuson heartbeat). having been for a few drives in a s/c v8, the only question I leave with I why I never went down this track years ago.

[Blown Monaro]

The set up in my Monaro is now ten years old but has only done 36000kms. Forged 382ci, whipple 2300, fuel system, intercooled, boost referenced water injection made 555rwhp, all Ive had to do is oil and plug changes, no regrets here and if I wasnt playing with Harleys and dirt bikes my E3 GTS would be blown as well. My set up is the same as run by Chipmaster is their Monaro back in the day, based on the Starr kit.

Is that a 2300 Atomic?

yes it is , on 11 lbs boost with a 224x228x114 cam ect ect

Sounds like it would be awesome to drive. Well built too

Very nice, thanks mate

Mine is 404 cube cast iron block, trickflow heads, cam 226/238 114lsa .600lift, harrop 2300 at 10.8 psi. I have a 80mm drive pulley instead of 85mm only because I already had it on the shelf.
Mechatron, the heads that Offshore mentioned are awesome and if you can afford them just buy them. You will then have 700 hp at the crankshaft roughly.

[VHSLE]

This is mine, Magnuson Heartbeat on an LS3 auto (standard stall), small cam, standard HSV extractors cats and bi-modeal exhaust, 431rwkw, all done at Sams.

I love it, drives like factory if your gentle with it but can become real nasty in punch of the right pedal.

It was only done in July so I'm pretty much still in the honeymoon period.

Best car I've owned, I can't imagine what the guys do with more power than this.

Can't attest to driveline longevity etc as it all still ahead of me really.

I would tell anyone to do it if you can, what other car can you do this to, how long will you be able to do it for ?

Grab one while you can.

Damn that sounds tuff as. As for the heads, approx what would be the cost for the ls3 mast heads?

Good write up mate. I really do love the look of these Heartbeat blowers

[offshore]

The mast heads are not cheap like with valves and springs etc complete its 5k or there abouts and thats not including rockers or pushrods and lifters and head studs. Probably not worth it for what you want unless you want heaps of power or you want the LS3 intake manifold to use the heartbeat or latest harrop blowers. Blowers love heads and cam though just frees up the restrictions and flows more air with less boost so lower temps.

Thanks mate, if that's the case I'd probably give the Mast heads a miss

Rather than spend those sort of dollars on heads, you would be far better off forging the bottom end and keep the heads you've got (just lower the compression with dished pistons) then you could happily crank the boost to 15 psi reliably.

Just put a 2300 blower on what you've got, if you get bored and want more, forge the bottom end and swap pulleys for more boost.

a couple of pounds of boost is going to make more power than a $5k set of heads...
