I'm pretty sure the timing was retarded by the ECU or intentionally by Delicious knowing he would be running e85 most of the time. I'm sure they could have forced a tune, but it may have been risky.

Dyno tuned the car today.

The low line is my car with a tomei header, untuned... the best I've got for a baseline.

Do you think the numbers are off? Looks like you went from 138whp to 282whp and 124wtq to 224wtq. Seems like the base numbers are low unless the untuned header was killing your hp. These are big gains or decent numbers with a custom tune n a header. Stock pulley on 91 or what?

The car made 158whp/132-ish wtq tuned with the header. Numbers are accurate. My dyno reads on the lower end for these cars -- a stock 6MT dynos 148-150ish.

edit: I've never seen an untuned header hurt power.

Gotcha. So those are sweet gains. Looks like 120whp+. E85?

280whp is an insanely good number for this kit with just one exhaust mod....to the extent that I want to go out and get that Tomie UEL header right now.

This is stock pulley and on 93 I assume....?

I don't know what the "stock" pulley is. The one the kit came with originally was total junk and we swapped it out to the next step up one. I don't think I'd recommend anyone run the base pulley...

Car makes 11.5psi @ 7300 rpm.

Car has a 100% stock fuel system. If you can get E85 to work on a 100% stock fuel system with this blower (or really any F/I making 10psi+ boost) you've met a miracle man... -_-

Junk? Junk quality? Junk psi output? Not in the kits ideal efficiency range?

This guy used a smaller pulley too, 10psi. One of the first ones to get the kit from the other Harrop thread. I don't know why he didn't do a 4th gear pull with 93 or why do a 3rd gear pull at all. 4th with autos are 1:1, right? Anyways, in 3rd he made 270whp with decent mods. Who knows the other conditions like altitude or weather.

Not ideal boost levels -- I felt it was too low. Maybe it's ideal for someone elses use/application.

I don't see a baseline for that car so those charts provide virtually no meaningful context. I see most Dynojets baselining 20-30hp higher than the FT86 do on my dyno (at least the ones I've seen locally).

With E85 I feel the pulley Jay is using could make ~300ish (it makes 11.5psi @ 7300 rpm, and about 12psi at 7600 rpm), but we need an injector upgrade first. That would be a solid 160whp+ over his "stock w/ raceheader" baseline and over 140whp over his "tuned w/ race header" baseline.

Great kit from Harrop, very clean install, I liked it.

Yea i agree the numbers you're getting on this car n kit are great.

The standard pulley is 95mm. I guess you've gone to a 90 or 85mm.

It's good to see a tuner drop the pulley size by default - should in time prove that it can be done safely and mean that the rest of us are basically missing out on free power.

I would like to be up around 260-270whp myself. Currently at 240whp with the standard pulley and fully stock exhaust.

Will it show gains, right? Thats the real question when you say work. More psi could just result in more knock causing the motor to retard timing which gives it less power, right? Im curious too. Where is the starving point for the injectors and where is the point where knock is an issue on pump gas?
