No sorry, I totaled that car Sept 2018 and do not remember what duty cycle the injectors were at for that. And yes that was 93 octane.

It sounds like what is needed for 500whp Na will interfere with sc later. Btw does anyone else feel night fury intake duration is pushing it a bit?

The converter is why Ben at GPI didnt set my shift points even higher, because I make peak HP at 7600 but continue to carry it out to 7800 RPM until the stock heads can't keep up. Go big on the converter. And mine shifts at 7600, 7400, and 7400 in the 1/4

The intake doesn't start to work its magic until after 7000 RPM. Just make sure you do the supporting valvetrain mods like a trunnion upgrade and have a good tuner...

And this photo will show you what the powerband is wanting to do. Now, I know you are going for boost, which, so am I, in a centrifugal supercharger build, so know that the LOD will support that very well. It just rules out a PD blower.

Yeah, the LOD is a good look, but it kinda forces me to procharge or turbocharge the car...

Wish I had a manual, lol

I was thinking that the nightfury and the LOD intake would work well with the boost, and those are the most central things to the build at the moment, besides the Vararam ram air. (what does "sc" mean?)

Also what would the intake duration have an impact on?

Greenhornet2 · 12-26-2019, 09:54 PM

Intake duration affects valve overlap, something you don't want too much of on a PD supercharger setup, you just blow the boost out the exhaust.

Oh, well then I guess I'll have to turbocharge the car.

That's the end of that one.

pnwdan · 12-26-2019, 11:04 PM

With the amount of money it takes to get the L99 to this point, you might be better off just throwing boost on it.

I'm thinking LOD X1 intake, Nightfury cam and that Circle D converter (just dont know what option to get for my car...)

Kinda wanna wait on my decision to boost it, since there is now a certain look I want to go for with the engine bay, I'm even considering to twin-turbo the thing for that reason.

From what I understand the LOD isn't great for daily and works best in high rpm.

It works just fine for daily. The power band is in the higher rpm range then the factory piece. If your goal is 500hp you'll need a mid rise or high rise intake.... like the LOD.

The same principles apply for turbos. If your intake and exhaust valves are open at the same time you will not be able to build boost in your cylinders which will rob you of power. That's the same for all boosted applications whether positive displacement supercharger, centrifugal supercharger, or turbo(s).

Greenhornet2 · 12-27-2019, 07:32 AM

Turbo requires even less duration than a sc to be effective. It's not that it won't work. Any cam will work it's just you won't get as much boost out of it, fou have to spin the turbo, sc whatever faster to get the same boost level if the cam is too big. So, to me, building badass fast NA car doesn't always play well if you plan to boost it later. No matter what if you stick boost on something you are still going to gain power it just may not be as much power as if you were building for boost to begin with. Lots of guys swear by running stock cam profiles with turbo cars especially since at lower rpm you are not building much boost so when there's a bunch of overlap that boost is even harder to achieve. I've done a lot of research and read a lot of different things. I'm not an expert, i'm just going by what i took from my research so take my advice with a grain of salt. I've always stuck with the general rule of thumb, on boosted applications i want 10 degrees less intake duration than exhaust and .20 less intake lift than exhaust. If you are going big on a can lobe separation of more than 114. But there's a lot in play. If you have a smaller profile cam on a turbo you can run a tighter lsa. There's so much research and so much in play it's not an easy answer. I'd suggest if you really are planning on boosting it to just buy a cam profiled for what you want to boost it with right away. I ended up buying jannettys rough idle sc cam. He recently posted a dyno run with his smooth idle sc cam on a turbo car and it made like 760whp i think.

No lack of torque in the lower rpm range?

Remember with a bigger cam and higher stall converter, you'll be in the lower rpm range less anyway

Clarkstar · 12-27-2019, 02:07 PM

My dyno numbers showed a loss of torque... buy I can't really feel it. Pulls like a raped ape!
