Fair enough, not cutting you down trying to empower you and bring you up to speed with what I have learned and gained by not shopping at those retail stores.
Also is not about money, you have read me incorrectly. I think you should spend twice as much, seriously.
Anyway of course go crazy with the stickers and badges man, your float your parade.
Are your posts always going to be ignorant of what others have to say? Elitist and ill-informed look and read like a pithy sales brochure?
This is a forum as in free speech, not meant to be offensive suggesting you review the choices in light of those with more experience. Harden up sailor. Worse things happen at sea you know?
I'm happy to leave it at that.
Well I think that about cover the topic of pro's and con's of said supplier. Lets drop the subject and continue onward.
Monstar is rather passionate on this particular subject and he's like a dog with a bone (or a Pir4te with his brew ) and struggles to accept other people may take a different route to that he has chosen.
Hey. Heard u are after perhaps to supercharge your redline. Abit curious as to why u didn’t buy the factory supercharged one in the first place. It’s got the engine that’s factory designed to accept supercharging.
It seems a lot of people do the PD supercharger on the high comp engine but I’d be a little concerened about the cylinder pressures at lower rpm. A centrifugal prob better for the engine although not the torque of the PD blower down low.
Anyway is not personal, let’s kick the ball not the player.
The (W407) 224/228 cam is designed for NA not anywhere near optimised for supercharging, although of course you can puff up any combo.
Weird the claim of 547 Kw with said components in that kit actually, especially given reviews best package mid 4s 0-100.
Maybe they are using the n/a style cam with the supercharger to bleed off some boost/cyl pressure at low rpm for the higher CR of the n/a engine?
I prefer the look of the Holden over the hsv also. As u have said lots of others have gone the PD blower with success but they would experience heat soak and the water /air intercooler would be heat laden. The ecu will pull massive timing once a few bursts of acceleration occur and reduce power by as much as 20%, hence possible lacklustre acceleration times.
One solution may be to run flex fuel with a view to mainly run e85 which will control heat and thrive on the high comp with boost equation and get the biggest and baddest intercooler u can purchase.
I had the exact same issue with my supercharged 540i with centrifugal blower (10.5:1comp). The first burst of acceleration was brilliant then subsequent ones were reduced. Fixing up the intoercooling and removing the Ac condenser means I have full acceleration whatever the use and conditions. Even in high summer temps the performance barely drops off. Now looking at permanent e85 for insurance and to ensure consistent performance.
A lot of guys out there are using interchillers.
Heat soak is the nemesis of all valley mounted blowers
If you want to hot lap a PD blown car and you want AC then the interchiller system works well but don't believe the hype that it's free power....
E85 is brilliant for blown cars (unfortunately it's not available at the bowser here in NZ )
edit: you just beat me....
That’s a band-aid solution for some drag racers, not a sustainable way to overcome the massive thermal inefficiencies of supercharging a petrol engine.
Yeah maybe, is like the VCM 262 from memory, bleeding off sort of goes against the description of low rpm torque gain though. Need advertised to check events.
I’ve done a fair bit toward achieving high thermal efficiency from of this engine, is at 37% on e85, makes about same power as W547 but more reliable.
