Konrad 800 SCI by R-tech Performance
 

Tom from R-tech just shot these over to me. R-tech's new 800 package is up and running...very well I might ad.

I'll let Tom fill in the details!

Here's one from the Miami show

It's not a flame arrestor, it's a massive intercooler, big boost, minimal intake charge temps.

That's an intercooler...

Specs on the motor please.
Bore, stroke, CR, carb or FI?

Need to do something with that intercooler cover. Looks to plane. How about something like "Rtech 800" engrave in covers?

The owner will be engraving the lids in theme with the boat. Covers on the Konrad 800SCi package will be engraved as displayed in Miami.

As far as specs, the Konrad engine is 540 CID tall deck, 8.75:1 C.R., EFI, aluminum heads, mild hydraulic roller to produce 800 HP @ 5200 RPM with 7 psi; a very conservative setup.

The engines in this particular boat are 557 CID built by Jason @ Performance Marine. Because they were originally built for Roots blowers, they are lower compression, so we are going to install different blower pulleys and run more psi. In this configuration we will see 900+ HP.

The owner doesn't really care about the HP though, he just loves the fact that they start and idle like 500EFIs.

nice pics biggus.

Its nice to see something other than a #6 behind some power for a change!

Whats the difference between that drive and other Konrad drives??? Or are they the same????

The majority of the Ace drives are ordered with the shorty lower unit. The upper is similar to the standard Konrad 540 with some internal changes.

The drives have been great behind my Innovation 800's.

I am very skeptical about this setup. It needs to be tested. PM me and I will give you my address to ship it to and I will test it out for you for no charge. :evilb:

The owner had a good time at the Alexandria Bay poker run with the 800 HP tune. New pulleys have been installed in time for the Georgian Bay poker run tomorrow. Water testing showed 10 psi boost with the new pulleys. These engines start and idle so smooth you would never suspect the HP level. I am very impressed with the sequential EFI programming done by Jason.
