All I got to say is WOW. Keep up the good work.
Your engine bay makes me wanna creame.

 

good luck at the shootout!

 

Wow, I am almost considering canceling my trip to India to participate in this shootout!
I guess there are going to be some sick cars yours included!
Bump, 4 the video

 

How is the parasitic loss eliminated again? What does a boost bypass have to do with parasitic loss? Unless your pulley is on a clutch that disengages at a certain boost pressure is met the roots type blower your using is eating HP.

If what you say is true that supercharger's boost is bypassed well how is your motor now diplacing 4.0 liters if all of the PD boost is being bypassed once the turbo hits some predetermined PSI?

I'll be waiting for a response to the above.

 

You'll never know (actually I'll eventually explain in detail how everything works). There is more going on than just a boost bypass. There is no predetermined PSI that causes the supercharger to disengage, it doesn't work like that. Trust me, you won't be able to figure this system out. Wait for the dyno charts and 1/4 mile times. I think that you'll be impressed. This has been very well thought out.

Again, the purpose of the project was to run a huge turbo at 5800ft absl without using Nitrous. Do you have any other ideas?

I could have strapped a GT40 or GT42 onto this car and hit boost at 8,000 rpms up here but I decided to try something different. The person who designed this is very talented and has wanted to attempt something like this for years. It's not the cheapest big horsepower setup but it works well and is very different than anything else that has been attempted. It's been a fun project.

 

Well, let's use some logic here. A supercharger is belt driven off of a drive shaft, right? In a car that drive is the crankshaft pulley.....I've seen people use shafts attached to the water pump pulley and that in turn drove the sc pulley, but in the end sc are belt driven. The only way to stop that drive/parasitic loss is to stop the sc from being belt driven. The only way I can see to do that is with a clutch...if you do not have a clutch you are not making that loss go away.

Your goal is to have a autocross car one weekend and a drag car the next while still having great street manners it seems. You are going to have one nose heavy EVO with all of that plumbing up front....I won't speculate any further except to say that your car will be nose heavy which will cause more understeer...a trait that EVO's already have.

Are you racing in Bandimere? All car's will have the DA issue, so at least you are on a even playing field.

If it were my car. I would put in a Magnus 2.4 stroker 8.5K-9K redline use a GT35R turbo at the largest and be done with it. If you need more power use N20 and a electric cutout at the track.

Good luck, it's real hard for me to see this working very well though. I'll be watching for your updates.

 

I already have the stroker with an 8.5k redline. It still won't spool a large turbo like a GT40 or HX50. I ran an HKS 3240 and it was laggy. You are correct about the weight, it is nose heavy. I will be racing at Bandimere. We'll know really soon as to how well this works.

 

dang! just read 23 pages and this sounds very cool indeed. the amount of engineering (and probably money) it looks like have gone into this is quite impressive.

can't wait to hear how you do once it's all tuned up and ready to rip!

 

As for your wheels, since traction is going to be an issue why not purchase the APR widebody and run 305s like RRE?

 

i am gonna have to fly in for the shootout. it seems most of the top evos are going to be there

 

Hiya John, still no reply from your man, i kno he's probably busy and trying to keep the cards close to his chest so i appreciate if he doesnt wanna tell me anything, jus tell him to let me kno thats the case. I can't wait to see this thing in action, i'd even consider a trip from the UK to Denver infact if i had any holiday left this year.

 

I have the 28ns and love them. The wheel really weighs as much as a set of metric wrenches.....i was suprised at how light they were(im running the 8.5" though). Not to mention, they are beautiful. see you at the shootout

 

He's stressed right now trying to get ready for the August shootout. Give him a couple of weeks, he will help you out.

 

I've been thinking about doing something like that eventually. We're just trying to get the car ready so we can race it for at least a couple of months before the season ends (October here in Denver).

This winter we are going to build a different engine that will allow us to take full advantage of the HX50 boost potential. The current engine still has the Toda pistons, Toda 4g64 crank, and Pauter rods. The head was built by Forrester/AMS. This winter I may have a low mileage built stroker engine for sale if you no anyone who might be interested.

 

Nice one fella i can appreciate that
