Look at the dyno graph thread and start doing some $/HP.
are you trying to tell me that 40hp for $40,000 is a bad deal?

Good point, but like you I had no choice.
More like $25k, a bargain!
Better than spending $10k on bolt on junk to lower ones hp....

Seems that the ratio for performance may be the same whether it's bolt on or rebuild. The question is how much you want to pay and in what order.

$10k+ for complete exhaust and software gets you between ~10 to 20 hp.
$40k for a 4.0 or greater top of the line rebuild gets you between ~40 to 80 hp. This includes the cost of heads/ports and nikkies.

In aggregate, ~$50k gets you between ~50 to 100 hp. You can cut the costs in half if you do the work yourself.

Speed costs time, money, snd headaches. How fast you want to go will tell you how much time, money and headaches you have to accept. DIY guys may spend less money, but their cost is time and headaches.

Speed just like life is a trade-off.

How about the VF supercharger for $10k with 150hp gain and 90lb/ft of torque gain?
Are blowers on this platform a terrible idea?

$10k then a $40k engine rebuild and $5k trans rebuild after they grenade = $55k

Curious, as I don't think this was asked, but WHY? What's your use case for more power? Assuming you can get your car to 450+HP what will you be doing?

Cool - should be easy for you to provide examples since data is readily available.

If you’re going to speak on the topic don’t you think appropriate to be prepared to back up statements you make.

Ya know, so people know they can trust your opinion is based on more than what you believe or want to believe.

Nah. If you want the info, you can go to the exhaust manufacturers and engine builders and get the info yourself. Easy to get.

@Fabspeed Motorsport

https://www.fabspeed.com/fabspeed-po...age-2000-2004/

$264.16/HP

If I use your example of a $40K rebuild cost and split your HP gain range down the middle to 60WHP (is this even accurate?) I get:

$666.68/HP

Seems like a pretty big difference to me… maybe I’m missing something.

HP gain/ dollar is not a linear function. Best investment may be a good set of tires.

As others have said, you won't get much of anything (if anything) out of the 996 engine by throwing money at it. The exception might be a serious bump in displacement, but that is a significant investment in coin.

Just drive your car, run a few autocrosses, and learn how to drive your machine.

Yep. Everybody wants HP until they learn how to drive. Then you realize you don't need it as much as learning to carry speed.

PCA has free instructors for both autocross and DE. Best freebie out there.

Poster - interested in bolt ons, any experiences ?

You - get tires and learn how to drive your car.

Define - won’t get much of anything, if anything for me please.
