The question of safely running E40 with a modified pulley is still confusing to me.
On one hand we have a post by Z OH 6 stating:
"FBO with a stock blower and pullies? If so, I can buy that, maybe even a 2.3 upper. Anything beyond that and E40 is likely going to run into a fueling limitation around 640-650whp."
David's dyno results on E40 are reportedly stated as:
"on the Mustang Dyno. Our final "Track Safe" pull hit 788whp and 839Lb-Ft of torque."
For a car running a 9.20 lower pulley.
Then in a subsequent post David is quoted as saying:
"This car was built so it will be reliable... the runs we made were Pump Shell 93oct, 20%, 30% and then 40% E85 purchased at Racetrac locally here in Florence. I have run my car all the way to E47% and only in the hot South Carolina humidity did I ever begin to have fueling issues with an IAT of 110º which lead me to adding more 93oct to reduce it to 40% to eliminate the issue."
Which indicates that taking his car from e47 to E40 eliminated the issue or concern.
And then as I stated in an earlier post and was told by David and will swear in court this is true:
"Because I also distinctly remember you telling me when you tuned my car on E30 that you had run yours with the stock fueling system on E40 but this was on the "hairy edge"
So this is confusing not so much for me personally as it should be for the owner of this car who under the advise of David and Patriot Motorsports USA has been informed by them that it's safe to run their car under the most demanding track conditions at E40.
Something is not adding up.
