cause the blowtards are too busy fixing their cars and the stroker guys are too busy shredding rear tires to bother w/an argument? hahaha... just kidding...

if one is considering a complete OH anyway, the stroker parts are the only extra costs, in addition to re-tuning. w/the sharktuner, even that is now feasible and a LOT easier/more accurate than ever before. but to do either w/out doing brakes, exhaust, suspension, etc seems kinda like missing the point of a pcar unless one is just lives their life a 1/4 mi at a time, to me anyway.

also, these cars are old. most have well over 100k mi, so even though a blower seems like a deal at the moment, the OH is still gonna need to be done eventually. and then you end up paying for both, which skews the numbers back to a stroker being more cost effective in the long run.

as for the stroker vs blower thing on practicality/driveability, I like the wicked ground shredding torque, simplicity, being able to survive a smog **** inspection at any time, the low end torque that let's me cruise at 2k rpms and pull like a train w/just a tad of throttle and the wide power/torque band that gives a massive area under the "curve"... oh, and the torque

flame away, ye ill-tuned, oil spewing, *** backwards vacume cleaners.. hahahha

Candlesmoker,

The "Stroker vs Forced Induction" non-argument is very similar to the "Factory Original vs Modified" non-argument in the respect that there really is no argument.

Different strokers for different folkers, that's all.















Now THAT was funny!

I've seen Joe and Marks strokers shred the track.....I've ridden in Tims 208mph Beast stroker that seems likes its idling below about 70mph....I DROVE Louies monster stroker (584whp).....& I "rode" in Robs street legal stroker.....needless to say they are ALL very impressive tire destroying monsters!!!

I've also ridden in a couple S/C 928's too....

Being that a properly setup stroker will still pass smog in CA is quite appealing to us here in the Republic of CA..... But the costs are quite high..... like said before think 4x the cost of a S/C or turbo....

Pretty much nobody builds a boosted stroker because of costs.....also there is the seriously limited lifespan of the driveline too.....Most of the stroker race sharks break tranny's on a regular basis (once per season or so)....so a boosted 6.5L+ would put down 700+whp easy......not much in the driveline can handle that!!

928SS

it's a compression issue that is the challenge. cramming 6.5L into the same little 5L chamber doesn't fit w/force feeding another 2L of stuff in there too

I've supercharged my shark; couple thoughts - if you have a 16 valve motor, supercharge - if you have a 32 valve motor, stroke it. The costs may be higher up front, but after building a 4.7 supercharged car, the cost differential is not that great - you just incur the costs over time rather than "up front" - also, in CA, it is impossible to get a s/c car to pass smog - not because it pumps out filthy air, but because it won't pass visual (my 84 actually runs cleaner with the s/c) - a stroked engine, visually, gives no clue to the smog station, so if it otherwise can pass smog, you good to go. I had an opportunity to see Mark Anderson's stroked 928 at Willow yesterday, and it sounds incredible and saying it was fast is an understatement (of course, having a driver like Mark helps, too....) - the bottom line is if you're looking for a long term, powerful modification, stroke it baby.

Please elaborate on the "cost over time" theory.
What are the "over time" costs for a supercharged car that are unique to installing the blower?
Unless you break something.
I call this a draw since the added power can effect any modified car.

I have nothing against strokers. I'm going to bore / stroke the 302 in my replica cobra. I just fail to understand your point on this issue.
To be fair, you went with what was bascially a prototype supercharger kit. This is not a fair comparison to a sorted out, proven setup.

I guess I'll speak up for the "reverse vacuum cleaner" crowd.

Stroker= big bucks. Write a big check, and wait......... Or do it yourself over the course of a year (or more) and hope it is right and stays together after you assemble it . You will have a new motor in the end, but will you put on enough miles to use up that motor? When it comes time to get out, how much more is that car worth. Most mods do not really hold too much value, but if cost was no object, it is a nice way to go. Also probably much easier to smog in California.

Boost has a better performance to $$$$ ratio. If I build another motor, it will still be in the 5 liter range, but just setup for more boost. I'm not too up on the other SC sellers, but I can call up Murph and have a new 87+ SC kit on my doorstep next week, install it that weekend and be done. Start with a healthy motor, and there should be no real issues. I put less than 5000 miles a year on my car, so I'm not worried about the extra stress. You are on boost for such short periods on the street, most of the time it is stressed no more than a NA stock motor. As far as area under the curve, search/look at the dyno performance thread, plenty of good stuff in there.

It is nice to have both options, something that 5 years ago we did not. Either way, the car is transformed into something it really should have been in the first place. These cars come alive at the 400 to 600 rwhp levels, as anyone who has driven or been a passenger can attest to.

You have to keep buying pulleys to push up the boost until you break something. That must get expensive.

hacker-pschorr

So far on that theory I'm out $100. That took me from 6psi to 17psi

How expensive is it with a stroker if you are all done, now want more HP?

now we gots things rolling baby... que the NOS and turbo crowd, 3, 2, 1....

Where are the Kuhn brothers when you need them .....OH , Right !

We don't argue anymore here in this forum, because every possible argument that could be conceived, was argued-out. There is nothing more to argue about.

Well there IS that dude in the UK who says he did over 200mph n/a ... and the other dude who ridiculed him, who in turn says he's gonna do sub-9's in the quarter after his NOS system is designed
