So what was the best quarter mile run and dyno on stage 1? How many miles did you put on stage 1 after it was finalized?

[AWD Addict]

Looking good

This!

[Blackstallion]

Cool -- I guess stage 1 wasn't fast enough...

How much ontop of 26k will this stage cost?

stage 1 is more then enough, 600 awhp plus ,but not for me lol its time to break 1000 awhp

[redman333]

If you go straight to stage 2 how much will that be?

Are you outright eliminating the FSI or are you going to run the port injection as secondary? Certainly interested in seeing where this goes. Dont really care about 1/4 mile times, just enjoy watching people try things differently. Lets see the internals!

What are you doing to the motor to attempt 1000 hp

sleeved bottom end,custom pistons and rods.race grade bearing,fully balanced and blueprint motor,basically she will take any boost level,no more fsi,full e85 flex fuel system,1650 cc injectors ect,,,,, too much to list

yes no more fsi,but the haltech will be wired in parallel with the factory ECU's

not even sure yet,but expensive

[FWP!]

AWHP? Are you doing anything to the drive train?

Is this type of build even doable in a "kit" form? It seems like such a high stakes modification that you'd really want something tailor made for each car...almost every big hp (7-800 HP+) 5 cylinder project I follow is pretty specific to each car, driver, location, etc. Id imagine it would need to be quoted per customer to avoid either risking blowing up a motor due to variations in fuel grade, air density, etc. or you'd risk under-performing what the kit is capable of due to engineering in "safe" tunes for all 50 states and their variables, no? Its definitely a world away from bolting on a blower and flashing a tune.

I personally think every forced induction setup should be handled that way. I don't trust any "kit" to run perfectly on my engine. I have always installed "kits" but had a professional tuner go over everything and fine tune the box tune that the kit comes with. Doing things this way has kept my forced induction setups safe for a lot of miles in all sorts of conditions.

Interesting... I would have liked to see what your other setup could have done if optimized...

It was pretty obvious that wasn't going to happen. Entertaining build to say the least but extremely poorly documented etc -- before you know it Mario will have another thread stage 5+

Now you know what I liked to see....your McLaren that you just picked up woof woof!

There's no way this is a kit. If it's ever sold, it would have to be an installed package at a set price. But, that really couldn't happen until many, many custom builds had proven reliability and gains. Underground Racing sells packages in this way, but they've done lots and lots of builds.

I wish this build was more open and not operating under a somewhat masked notion that this will end up being for sale.

the stage 1 is fully optimized and makes over 600 awhp,but now its time for more power,I'm going to run a full efi system on e85 and pouch the stock engine to its limits and see when its going to fail and what is going to fail,mean time I'm putting my fully built engine together

[Quattro_The_Dog]

Cool to see more updates and progress. Thanks for sharing.

You going to keep us updated here as to what power level it fails at and what fails? I'd like to know myself.

yes i will,going to run 1.2 bar of boost on e85 and see if the rods hold up to the power,i think we are all going to be surprised how much power the stock motor can hold
guys I'm your guinea pig lol give me some respect

Also forgot to ask what's your goal hp/torque with this Stage 2 of yours?

The guy in Europe that just did 1200hp says the block is okay to 1500nm and no sleeves are needed. I bet close to 800 is reachable with good tuning on 100% stock bottom end based on these new findings and old findings by MRC. I too vote the rod being first to go. But why kill a rare engine?

He already laid out his goals, 1000 whp and low 12s.

[Peter1.8t]

Lol low 12's. Spinning in 6th right?

It is a rare block but if I could do this I would myself. You can't move forward without pushing the limits.

Low 12s. What's JHM running? Hp and tq to 1/4 times. Or apr? I do t recall any others posting track times and hp #s.

1000+HP and still only running 12's, did I just browse into a Supra forum? lol

Looks like a good start anyway! :thumbsup:

Redman, I'm sure you could get Eurowise in Charlotte to do a custom TT on the RS4 for you for the same amount of money if not less. They just completed a custom TT R8. I know that's a different beast than the RS4, but their fab and tuning skills are up to par it seems. Don't count on anyone ever making a TT 'kit' for the RS4.

the walls of the cylinder are very fin,it won't take more then 20 psi all the time ,as when sleeved i can run 40 psi on it all day long,i mean we are all experimenting

Good to know. Thanks for the tip. I'll check them out.

no goal really just going to max out the turbos witch will max out around 1300 awhp on e85at 40 psi,but its all just a guess

There is a northernew California shop working on a rear mount, easy install twin and single kit. Their stated plan is to single it, then twin, work out the best package to offer to customers. So it might happen.

Respectfully disagree. When I had my Z a friend of mine he the twin turbo rear mount turbos and his turbos kicked in at 3300 where as mine kicked in at 3200. Sitting behind the wheel we couldn't tell the difference. Before he had his though I thought the same thing. In my mind it seemed like there was too much piping to not have lag.

Thanks for the vids. That's what I was trying to figure out. What times they are running. I was thinking 12s were a bit slow. Still quick but slow in relation to others.

it depends of the size of the turbos you are using,personaly i would rather have a blower then
