New best Holley

[TType85]

5. I have not changed the down pipe to a better boost controller with C02 as per an early recommendation.

Going to C02 for boost control was one of the best things I have done. The HP has built in boost control but you need 2 outputs for it (+ and - solenoids).

The 60's should be able to support a 10.5 power with ALKY. and 10.5 is probably the end of the 5857 too. And would E85 be something you one would use for a 10.5 car.

I will need a bigger fuel pump too and posable fuel lines to support 80's or 95+ for E85 All to consider.

I would do 120's minimum going to E85, you could probably get away with a hellcat pump for a 10.5 car. I went with a DW 810 brushless pump (810lph with when running full tilt). You would also need -8/-6 lines as the stock return line would be too small. I went with 120's but wish I went 210's as I am already seeing 80+% duty cycle and I haven't run it out in 3rd gear yet. The main thing comes down to don't cheap out on the fuel system as it is cheaper than a new motor

Also for the datalogs, in the holley software in the dropdown "Datalog" there is a button to Download ECU Datalogs. It takes a good amount of time to download the logs especally if there are a lot there.

But need to do more research on the E85 in my area.
This would take ALKY out of the equation too.
The 60's should be able to support a 10.5 power with ALKY. and 10.5 is probably the end of the 5857 too. An

The advantage is you have the computer system and could let it adjust itself off the proper map if the car is on e85
But.....
You can do it on pump gas alky if you want to make adjustments to the curve and look at the data and follow it.
It's a personal choice

210s is the way to go
If the fuel system and Computer is there

I would flow the 60lb injectors and make sure they are good

Sent out to be checked and flowed, Tested good, but cleaned and reflowed + 2%
Ill be sticking with the 60's and ALKY

Im digging at the data and ill be trying to go to the track to get more data soon

I think I have the HP data login figured out for my next trip but need to make short hit or two on the street first. , This would give me a chance to pull some ALKY out first too.

Timing is one of those things to look at too. Ill be baby stepping, first tame the ALKY then start adding timing and looking at the plugs a lot closer.

Thanks again every one

You need to be leaving the line with the alky on. And that should prove no issue at 8 psi or better for the alky.

Your map is fat with the alky causing the rich conditions so lean out the VE map where needed to get to the 11 to 1 off the line and up to 4500 plus in the rpm range. 10.5 above 4500 rpm will work.

Stage the car to leave at 3250 or better off the line and that will shave tenths off your 60 foot time.

Leave under full power, finish under full power.........

updated tune and a pass made the same night with 19lb boost hidden on my laptop
