I need 600. Hope alusil block wont complain.

Reversing the head doesn't really give you much extra power on the dyno guys,as I said my motor is mostly off the shelf parts.

gruhsy

But your engine is definitely freakin awesome looking

You should hear it go down the straight.

I guess short of billet blocks and fully custom cranks and cnc'd dry sump pans with integrated bearings etc...most parts are available via the normal aftermarket suppliers. Having said that, the guys like Sid and Shawn and others who have gone down their path have been able to find 'off the shelf' parts that are non Porsche and have obtained great results.

I would say that my motor is probably the most custom that I know of. Unfortunately I just don't quite have the funds to finish the installation even though it's now sitting in the engine bay. Being 'under turbo'd' isn't ideal but it's the same turbo as Gustaf has been running so it will give us a reasonable indication. Hopefully not too long before it is completed and tested and then we can see if all the waste of money shiny bits have been worth it.

Missing the $ in front of the 6.99?

Good to see it in though!

Lol..that's about how much I'd get back in every $100 spent on this thing....

That is truly inspirational. You Sid and Shawn are showing us a whole new way to enjoy our cars on into the future.

Patrick, I see you have separate provisions for lambda sensors in each runner. Perhaps you are aware of that but pressure affects lambda readings and that should be taken into account during tuning. Also it is not recommended to have sensors in high pressure environment permanently, it reduces its lifetime.
Taken from Bosch datasheet:

Thom

If I remember right he uses these ports for EGT sensors.

Raceboy

There are both EGT and lambda ports.

To build a 500 rwhp engine I don't think it's more expensive to go the 16v route. Simply because you don't need to spend a fortune on the head to get it flowing.

I built a simplistic 3.0l 16v turbo engine in the past. 514 rwhp at 1.15 bar on pump gas.
Stock 968 head. Stock 968 cams. Stock 968/951 headers. Retained variocam.

My current 3.1l is miles away from the above engine in terms of modifications. 682 rwhp at 1.5 bar on E85 with the turbo being the limiting factor.

Voith

What was the limiting factor on the first 514whp engine?

Duke

Well, I don't deliberately push every engine until something breaks
It ran a higher 9.5:1 CR so it felt like a good level for that engine combo.

Spending 10k on a 16v head for 500 rwhp is not an effective use of resources.

Cool, you are also on this forum, i have seen your car on Mantorp

500 rwhp is perfect for street/track use.

What turbo and ECU ?
