Tapp performance stage 1 capability

[jonx96]

Does anyone know how far the Rick tapp stage 1 fuel system can go on e85. I’m assuming it holds up to the 2.65 but would it also hold up to a lower and 2.65? I am doubting it.
Do you know if the stage 1.5 does?
how do these pumps compare to the redeye pumps? Out of curiosity

@jonx96 can you provide a link to what Tapp fuel system you have?

It is dual 285 pumps.

Looks to be similar to the hhp one and they have hp limit listed so I guess that answers my question. I think I'd be playing a dangerous game with the lower as well

I had the 274 pumps and 1440 Cc injectors and I would run out of fuel pumps on E85 with a 10% lower and 3.17 upper.
I put the 285 pumps in and now I'm good for both fuel pumps and injectors.

For reference on pump gas my 1440's run at 50% injector duty cycle at peak with 85 psi of fuel pressure and fuel pump duty cycle of 70%

On E90 is the 70% injector duty cycle
And 85% fuel pump duty cycle

This is the One that has been installed in Top Cat Challenger. I think they look the same, but I'm not the expert. I'd read the description and see what HHP says about the pumps it may help you.

I already regret the fuel system I have on the car. I wish I went bigger but maybe one day. Not this year. Sounding like I will just but dropping to a smaller upper this year. If I ever figure out which belt for a 2.65. My guess is K100570HD or K100564HD.

I see that the price dropped since I bought it. 😢😢

Bigger how ? There is only 1 pump sure bigger ( 295 VS 285 ) and it's only 10 LPH more .

Return system.
but I’ll be happy I’m sure just dropping pulley size. For awhile….

David I'll bet you also bought the line filter kit along with the Pumps?

Yep. It was supposed to go in last fall and then shit happened. Still not caught up. Plus I've decided against E85.

 

[jonx96]

@Hpindy long story short. There was a car and bundle deal I was trying to buy. The way the deal is falling through it has me in a mood to just make my current hellcat a lot faster.

I don't use E85. I don't have it near where I live and I wouldn't want to have to do the work to know if it was good.
I like the way my Car is Tuned. I can race or Daily Drive on 93 Pump, MS109 and when I want to go real Fassst I can use Q16, which is what Leon Epling uses with his Worlds fastest Hellcat!

Everyone has a different idea or what is easiest for them to use. For me E85 is all around me and way cheaper then race gas. I will get similar performance as ms109. Cost difference will be $2.25 to $15.00 a gallon and I can run e85 every day so race tune all the time

 

[DavidKFla]

There's only 1 gas station within 20 miles of me that sells E85 and from what I hear, it's not very good. HP has a software issue with a flex fuel tune so it doesn't work for me. Plus the shelf life of E85 is short.

Don't forget that you get to fill up more often too


I have Run Q16, changed the tune, Pullied down and added 93 Pump and drove home from the Track.

I agree, it is about what is easy.

Idk if I do something different but I only lost 3 or 4mpg when cruising around. I have heard a lot of people say they get way worst but I haven’t found that to be my case.

I like spending other people's money so if you need help in that department let me know
