Reasonable expectation from Procharger installation?
I am having it installed now was curious as to what to expect when I get it back. I will list my mods and what it dynoed and ran at the track and if anyone could give me a roundabout idea as to where it will take me that would be great.
Mods: TSP 2 inch headers AWE 3 inch Touring catback Rotofab dry (coming off for Procharger) Pray custom cam 229/239 .6xx 111 lsa Circle D 4000 stall SMG flex fuel kit 17 inch drag pack Those mods netted me 491 rwhp and 46x rwtq and ran 11.2 @ 122 mph. The car will be getting full LT4 fuel system with SMG auxiliary low side, Procharger with F-1a head unit, stage 2 intercooler and race valve. Procharger said they are sending the largest pulley they have to get a feel for how it runs and go from there but will be 7-9 pounds of boost. What should I expect to gain horsepower wise and how much quicker will this car go on low boost? I know the converter is a little lose for it and will be restalled eventually. |

LT4 fuel system is way underspec for F-1a unit. You should at a minimum thinking (assuming DI not dual inject), Lingenfelter 2.0 DI pump, 38% fuel lobe, and at least the 30% modified LT4 injectors if not the 52% Lingenfelter injectors (K-D). Heck even a P1 can exceed the LT4 setup...

LT4 pump, 32% lobe and LT4 injectors I'd say 650 HP on fuel but I really don't know the limit given a 6 ms injection window. I'll leave it to the guys that run this. From memory I was on 5.5 ms with: Lingenfelter pump, 32% lobe, LT4 injectors at 7 to 8 PSI of boost full build engine pump gas. It was a little rich but clearly by 10 PSI I would been out of injection timing which would be a 4" to 4.15" pulley on a D1x pump gas.

I have been told by most people that the low side is the first to run out with the LT4 system but I don't know this is all new to me. SMG did say that the exact system I got from them with a 32% lobe did 960 rhwp on E85 in their shop car so who knows now.

IMO even with a 32% lobe you will rapidly run out of fuel with LT4 pump and injectors on pump gas. I would encourage you to at least think about a Lingenfelter pump, especially if you want to run E60 up.

Yup, it will be interesting. Now that I have a lifter issue, I may go to a much bigger cam with 38% lobe. Lingenfelter should have a 8.5mm lobe out??? or is this an Area 51 myth.... I gonna storm it and let you all know.
https://www.lingenfelter.com/product...l#.XS4pI3dFyUk Interesting the Lingenfelter has 38% lobe, LT4 high side for their 800 HP (about 680 RWHP) setup and for their 1000 HP E85 setup, they use their high pump and K-D injectors. https://www.lingenfelter.com/category/C012016.html

I will definitely return to this thread and update what happens for future reference and people looking to go the same route.

Maggie @ 9-10psi Cam LT4 fuel system JMS booster Always end up in the 680-720whp range. With your smg low side you can probably run E50-60 @ hit right at 700. If you had pistons, I would say turn it up to 12psi and it would be in the 750-760whp range. The next hurdle to go above that would require 30% injectors and a LPE DI pump to run E. Or if you did pistons and lowered compression to LT4 range you could get there on 93. At stock LT1 compression you will hit a octane wall on 93 around 700whp. This is all based on No use of Meth.

32% lobe with LT4 system has been proven to support 9-10psi on e50-e60. Your F1 isn't going to require any more fuel then any other supercharger at that boost level. It's potential gains won't be realized until you start spinning it much harder where smaller units start to lose efficiency and create more heat. What Oldman was trying to tell you is that you will run out of fuel system before you ever tap the full potential of that F1. If you were only planning to run 7-9psi, then you could of just went with a D series. F1 isn't even getting into it's prime operating speed till about 15psi+. You will likely take a hit on low end spinning that unit for only 7-9psi. It's no different then properly sizing a turbo for the application and goals. If it didn't matter then procharger would only offer 1 or 2 units.
