Improving my HCI LS1
So, the short answer is: boost it.
If you've got boost questions there is a decent group of us who've build several setups. Feel free to ask questions. How much boost can he run?
Seem's like for the cost of an fi system, it wouldn't be worth it.
If he want's to pull the engine apart and put in some different pistons to lower the compression then I could see it.
If not, then nitrous seem's like a better choice.
I have a much larger SNS 3 cam (235/243 .630/.615) and 225 heads. Ls6 intake is my biggest bottle neck right now, pulls vacuum from 4500ish and up in my logs, I have seen as low as 87KpA@6-6500ish rpm....the longer the gear the worse it gets. I.E. first& second isn’t too bad, but top of 3rd and 4th you really see it. Might be worse if I was an auto as the skinny pedal never lifts lol.
hard for me to justify a 102 and the 600 dollars of crap on top of it to make it fit. So I’m interested to see how your 92 does as I’ve been so torn on it. I’m waiting for my car to die a knocking death and it’s hard to me to spend 1600 on an intake I won’t use on my new motor. Bad enough I’ll have over 2k in heads I’ll have to eat...it’s a fact ROI is bad on NA..always wish I would’ve went procharger. Feels like I’m digging a hole with a damn spoon while these boosted guys use a backhoe lol
But back to this case, just speaking From my logs your heads and cam should benefit greatly from a better intake as I pull a good bit of vacuum. I think youll be happy with the fast while you save for FI.
I too recently have got the dragy and it’s pretty neat, haven’t played with it much due to winter. Did one play run so far to test it

Don’t get me wrong, if I thought my motor would live forever I’d be on the whole 102. But I’ve got so much money into this car as is I don’t wanna put that much investment into it then not be able to use it when she pops and I get a bigger cube mill..being it has nearly full suspension, MWC 9” and being it’s the car I wanted, a WS6 with 3 pedals, I would replace the motor. if it wasn’t for this car I wouldn’t have been in the local car scene network and never have met the wonderful woman I have lmao. It’s become sentimental to me almost. Very dangerous combination of a money pit lmao
The 92/92 setup is about all I want to afford for this little Ls1. My luck is the damn thing will run for another 50k miles lmao. She piston slaps like the dickens when cold, and has lived through a ls7 lifter wheel breaking clear in half, a crazy ex dumping sugar in the gas tank and then the valve cover.. I change the oil about every 1k-2k with 0-40 and it sees abuse every time it leaves the garage. So it owes me absolutely nothing.
Still though, please do let us know how the 92/92 works vs the ls6 intake. Would be a decision maker for me.
also, I’ve read the msd doesn’t out perform the fast setups until you get into the really high rpms
