Maggie 2650 on LT4, stock fuel okay?

JasonGofast · 09-17-2020, 01:26 PM

Looking at getting my car modded soon. It is a completely stock 19 A10 ZL1. After looking at what I can do to reach my power goal of 700 whp(for the time being) I looked at what could be not the cheapest but the most simple option...just getting a bigger blower.

Will the Magnuson 2650 require anything additional done to a completely stock engine for me to reach my power goal and keep the car reliable? The only thing additional I was considering was a 103 NW throttle body. At some point I will get headers and a rotofab intake as well. My only concern is fuel, and whether the stock fuel system can handle my goal. I look forward to any insight someone knowledgeable here can give me.

You should be fine at 700 whp if you are going to tune on 93 octane. If you were running e85, you would probably need some fuel system upgrades to run straight e85 or alternatively run a blend of e85 and 93 oct to make an e60 blend as many others have done. The latter keeps the fuel system happy. This is from reading many members trials on this forum, im sure some of them will chime in.

I would recommend you order the 103 snout and the NW when you doing the 2650. The snout is discounted when you purchase it with the kit. I think I would consider a JMS boost a pump also just for safety in can you want to exceed 700 just a little, especially if your considering some E content. You'll have to modify the valve covers which I did the first time but ended up getting the Speed Engineering Billet covers. They look awesome also.

I’m hitting 824 Rwhp with a 2650, headers, lower pulley, Rotofab on 93

These threads make me happy, & sad at the same time.

Impossible. The stock fuel system is only good for 700whp.

You need to be running a Cam/Meth to hit that horsepower.

If I were to go for fueling mods I think the most I would do is an auxiliary fuel pump. I'm not sure how much power I could get to with this added in the set up, but along with a voltage booster is about as far as I'm willing to go. I do not want to cam my car and getting new injectors...well it'll probably be a lot further down the line before I feel like spending that money.

Thats plenty and you'll make some great power

Get the JMS now and if you want more later look at ToohighPSI Port Injection setup if you don't want to spring for +30 injectors.

I like that torque curve. I am not interested in running a cam yet, maybe much further down the line. I wanted to know what I could get away with no fuel mods, and then only low side mods. I wish their was a guide that says the approximate limit with each mod and combinations of them but that would be a lot of R&D.

Without a cam or meth, your looking about 700 rwhp max, doesnt really matter what bolt ons you use. The boost a pumps don't really do much either. If your just on the border of say 700-710 it may help you get there, but that's really it.
