GTX 4202/Semi PPort/ E98 project done...
Hey guys. Got my new setup all finished. Ray (PFSupercars) will dyno tune this weekend. Im very pleased with the finished project. To compensate for the E98 fuel, I upgraded the fuel system to two -8 feeds. Im anxious to see what the GTX does with this fuel and Semi PPort. Big thx to Ray Wilson for getting her buttoned up. I'll post dyno #'s when we're done.

Its street ported. Thx
6 injectors total
2 1000cc primaries
4 1680 secondaries
The E98 is better suited for higher boost levels.

cutting edge stuff w that turbo. congrats and good luck.
i couldn't help messing w the numbers so here's what i see as to max hp.
BTUs
ethanol 84530 per gallon
gasoline 124,340 per gallon
E85 90,501 per gallon
BTUs to make 600 rw rotary SAE hp...
80 pounds per minute of air
7.44 pounds per minute of gasoline at 10.75 AFR (rich but hey we are at 600 hp)
7.44 pounds/ 6.35 (weight of one gallon gas) = 1.172 gallons
1.172 gallons X 124,340 (BTUs per gallon) = 145,683 BTUs to make 600 rotary rw SAE hp
you run:
2 1000 CC/Min primaries
4 1680 secondaries
8720 total deliverability at 100% duty cycle. let's assume you run at 90%.
8720 X .9 = 7848 CC/Min net of duty cycle
7848 = 124 gallons per hour or 2.07 gallons per minute
2.07 X 90,501 = 187,337 BTUs
187,337/ 145,683 (BTUs to make 600) = 1.286
1.286 X 600 = 772 rw rotary SAE hp.
787 standard correction
the above assumes no peripheral intake ports
assumes 10.75 AFR
assumes you don't crank up the rail pressure to get more fuel.
it will be interesting to see where it shakes out
good luck,
howard

For me to hit 160mph, at 2880lbs, Id have to make more than 850whp. Thats not happening lol..not on this turbo anyhow. Maybe the 80mm.

2x1000cc + 4x1600cc is nowhere near enough.
E98 max power rich will be close enough to 6.4:1 air fuel(mass for mass). 100lb/min air will need approx 11000cc/min fuel flow to correctly combine and operate around peak of 87% duty cycle.
100lb/min air divided by 6.4 AF = 15.625 lb / min fuel flow.
Indy whites are 152lb/hour aka 2.5lb/min
ID2000 around 190lb/hour or 3.16lb/min.
You would be looking at 6x ID2000's as a starting point for maxing a 100lb/min turbo using that fuel type. Because alcohol fuels make awesome power rich you are basically working off the research octane rating, so power will come really easy.
E98 research octane rating is close enough to E100s 123 points.

Ernie, awesome setup as usual.
Would love to know where you're sourcing E98 from. Are you getting it from the ethanol refinery that just opened up in the Richmond area? I really need to locate E98 to "roll my own" E85 all year long and account for season "E85" changes percentages.

I have two close friends with the same exact injector setup using the same fuel and have more then enough injector. I appreciate the concern, but Im in good hands.
