I’m finally getting around to an intake manifold upgrade on my setup. I replaced the stock LS1 manifold with an LS6 when I did the heads/cam swap project last spring on my C5. As of right now I have 346c.i. LS1 with PRC 2.5 5.3 heads, Torquer V3 cam, stock LS6 intake, stock throttle body, 85mm maf, Blackwing intake, 42lb injectors, 1.75” long tubes and 3” offroad X. The setup is currently putting down 430whp/400wtq. I know that stock LS6 intake is restricting a decent amount on a H/C combo.

My two considerations as of now are:
1) fully ported LS6 intake and P&P LS1/6 throttle body via Bare Essential Racing (BER)= $330
2) ported Fast 90 or 92 and P&P LS2 TB via BER= $710-810

Anyone care to share what gains may be had with either upgraded manifold. 450hp at the wheels sounds like a nice number and I’m sure is more than likely even with just the ported LS6 stuff. Just trying to get some ideas and opinions.

Cliff note: Whichever intake setup I go with, there will be before and after dyno sheets of the intake manifold and throttle body upgrades only, done at the same shop.

I'm a believer in the FAST's capabilities. I had a port matched 92 from Ron @ Vengeance and it was well worth the money spent, and I bought it and the NW92 new.

There is really nothing to port on a LS6 so BER is selling Snake Oil......

I haven't seen very positive results either.

Either be happy with what you have or try to find a good deal on a Fast. May or may not find the 20rwhp you are looking for from a ported Fast.

From everything I have read, and talked to my tuner about 20rwhp with your setup is not uncommon at all. I put on a FAST 92 and have the same setup as you except with ls6 heads, but won't have any new numbers until April. I'd think about putting a FTP 98mm lid on while your at it.

One thing to check or have BER do for you is port matching. It was horrible on my LS6 heads....3/16" overhang on almost every port. I did it myself but it's very time consuming, took me all weekend to get straight and smooth.

Thanks for replying all.

Spoke with BER today. I was told with their ported LS6 intake and throttle body I could expect about a 20-30whp and 25-30wtq gain over the stock pieces on a setup like mine. Mind you, that claim was not for a stock motor. On a stock motor gains would be much less. And if I'm not satisfied with the results they will give a refund. But he said I won't be disappointed. Hmm... I cannot imagine for the life of me why they would BS about this, especially with the refund thing. Since they've been porting and testing intakes and TB's for a while now, they probably know what to expect. I seen their ported LS3 intakes are pretty damn impressive.
20-30whp and 25-30wtq gain would be one hell of a deal for $330.

I mentioned to BER I'd be doing a back-to-back dyno for the ported intake and TB also. Another reason why its hard to believe they'd be throwing out BS claims.

i'd like to see it, keep us posted

In for results.... I'd rather pay 330 than 900 for the lump-o-gold FAST

Anyways, here's a good read for those that's interested. At least BER stepped up to the plate.....

There isn't much to port on the ls6, due it being one-piece, but it's not a bad idea to get done when doing the TB anyway. I'm going to post my results, getting both done this week.

edit: $300+ is a litte steep and expect closer to only a 10-15hp gain.

im a fan of FAST though they do charge too much for their stuff imo.

I just dont see it, they gained 7 hp on a 500 rwhp car so the gains would be lower on a 400 rwhp car. The only thing I would do is open the LS6 to 85mm and add a FTP 98 lid. Other than that ditch the LS6 for something like a BBK, PP Typhoon or FAST

Curious, does anyone here have experience with BER ported intakes and TB's? Or seen any results from their porting work?

Them are some pretty confident claims they emailed me today.

Who's "they", and where did you see this? I'd like to check it out.

I was referring to the link a few posts up, a ported LS3 by BER gained 7 hp. If the LS6 was portable everyone would be doing it and running them. But in 12 years only 1 company that I know if other than BER modifys LS6 intakes and even they just open the inlet to 90mm

R6cowboy

iTrader: (3)

Ok. I was told they open the inlet to 78mm and fully port the runners to get the most out of them. BER emailed me the cfm numbers per runner, stock vs ported. So they don't port only the inlet, but the runners as well.


I haven't seen anyone that actually has experience with BER's port work. Hopefully someone that has will notice and chime in.

I wonder what the capabilities would be with a TPIS 90mm LS6 with the BER porting....

Well ****, nevermind. Might as well buy a FAST at that point.

I'd be willing to trade a full set of body armor with plates for a 92mm at this point

Yeah, I don't know man. One thing I do know is a friend of mine who has a modified LS6 intake with 90mm inlet on his N/A 402c.i. LS2 C6. Stage 3 ported 243 heads, cam (I don't know specs), LT's, full exhaust, CAI, stock maf. His car makes approx. 600hp (I've heard 613 crank), well over 500+whp and I believe every bit of it. His Vette absolutely rapes mine. Yes I driven it. He gave me the keys and told me to let him know how his Vette compares to mine. When I say rape, I mean its not even close. His car is a totally different beast. Both cars M6 trans and 3.42 gears. So the capabilities of a modified LS6 intake seems to be pretty damn impressive from what I have seen in person.

I think I'm gonna be going with the 90mm LS6, but was wondering about opening up the runners. I know the TPIS 90mm LS6 basically matches a unported FAST, so I wonder what increases BER is making in the runners, might match the FAST. But $350 for the TPIS mod and $200 for the porting is basically the same $ as a FAST. I only consider it because I had a FAST that broke on me and I don't trust them.

Just do the ber deal and when you dyno they can give you your money back simple and free
