With the D1SC I would go with the 102 Hi Ram

LSX-PWR

I'm going to go with the high ram 102. Now it's time to order that bad boy. Are they available?

MikeFSKSpeed

They are available sporadically. I have 6 I am waiting on. Holley is ramping up to produce more of them.

NemeSS

iTrader: (127)

got a mini ram 300-121 efi base in stock, ready to ship?

LSX-PWR

10-4 NemeSS. Although I think I would benefit beat from the high ram.

I cant get the Mid Rams in stock quick enough, or the bases for them. Still waiting on a bunch with no ETA.

Just got in a Pallet Today of the Hi Ram Cathedral Ports in 92 and 102mms

im kinda lost on all this stuff.
i have a stock ls6 IM now and am making 876/860 on a 383 turbo motor(6800rpm/18psi)\
im sure ether manifold would be a improvement to the stocker but how much better would each be over the ls6?
i dont really want to cut my hood but i will if it THAT much better
help me out here guys

Personally I think with the 383 and the boost you would see some good gains out of the additional plenum volume of either the Mid Rise or the Hi Ram

Q

Had to use 1/2" k-member spacers and cut the cowl and remove the wipers. Made 50 extra HP over an LS6 intake at 4000rpm!

Thanks for info.

Need context; engine specs, NA or forced induction. Pics look like forced induction. Can you post dyno sheet?

That looks badass, and the fact that it made 50hp more at 4000rpm is quite impressive. How did it do in other places?

LS1-450

iTrader: (33)

Think by now if stock stroke & 3.898" bore NA gains were worth a **** it would have been posted somewhere. All the testing I've found is either larger cubes or forced induction. After Holley's FOPA w/ the "Street Warrior," they aught to be on here giving these away to LS1Tech members.

It is a 99 Trans Am LS1 M6, stock bottom end stock heads, STS 67mm 15psi on E85. Made 595 with the LS6 and 617 with the Holley.

I will post a dyno sheet when get back to work on Monday.

The 2nd dyno grauph is the Holley vs. the LS6 intake, engine speed.

LS1-450

Thanks for updated info. Nice improvement through the whole run. Although, wish we could get some NA numbers somewhere.

Hmmm. Makes me wonder how it would perform against a ported LS3 intake. That sure looks badass!

The Alchemist

I've got to be honest, I'm not hugely impressed. Is there a gain, hell yeah, and through the entire rpm range, but I wonder how a FAST 102mm would have compared. Just playing devil's advocate here. I mean, you're giving up wipers, cutting the cowl, dropping the k-member for a decent gain.

Well I never drive it in the rain cause of the rear mount turbo (hate the sock condom) plus we use k-member spacers on all the F-Body Maggie kits we do so that was no issue. I guess I wanted to do it cause no one has in an F-Body plus it does look sick! I get compliments on it everywhere...
