SVS First Flex Fuel Viper - E85/93 V10

[SVS Turbo]

Before we added the e85 flex fuel sensor this 98 GTS project started with a stock engine and was complemented with the following components:

SVS headers
SVS rear mount turbo system (1 76mm GTS turbo)
Air/Air intercooler
T&D rockers w/ Manley 3/8 pushrods
SVS fuel system
Motec engine management

More can be read about the first stages here:

SVS rear mount turbo

New additions to the engine, fuel and ignition:

Ported and polished heads
JE pistons (lower compression)
SVS Turbo Cam
GM inline e85 Flex Fuel Sensor
SVS coil on plug ignition system

The e85 flex fuel sensor communicates with the Motec engine management
and makes all necessary compensations for any percentage combination of the 2 fuels. It's quite slick and will allow our customer to run 100% e85 at the pump or any combination of e85 and 93.

Our first tuning session on e85 has produced 600rwhp @ low 130's kpa (4-4.5psi) with conservative timing. e85 likes compression and it will be interesting to see the results once we start increasing the boost.

Very soon we will have a great deal of information regarding e85 testing on many different V10 engine platforms.

I was wondering when someone would start tuning with E85.

I mix about 5 gallons of E85 with Premium and it seems to run pretty good.

Did you have to nitride coat any internal parts to reduce corrosion? What was the reason for the coil on plugs? I'm sure they work good but they look like ***.

If you're unable to change your fuel or spark control running your engine then adding e85 will do nothing for you.

Did you nitride coat your engine parts since your adding e85?

COP Increases the spark

I know they work but more people go for looks rather than performance.

I have a VEC2 to control things. My crank is Nitride coated but not the pistons or valves.
