How much HP was the swap worth on your car.

Again, no gain would make sense. But a 50HP loss? I'm really curious to hear what's the cause.

Nose Up if I had known all of that before hand I would have bought an LSX to begin with. Thanks for taking the time to type all of that.
Pmack when I go back to the Dyno I will have him give me this info.

Well if you do go back to the ls6 intake, do you think you could get some before and after peak MAF readings? That would tell you for sure whether it's flowing or not.

There were no before numbers for the intake except for trap n et at the track.
His Dyno does not read low on other cars. I thought my car was just not a Dyno Queen lol.
I wasnt laughing at the track yesterday. I have seen cam only cars on his dyno make over 400. Their performance at the track reflected those numbers. As do my track times as of late.
I may not have lost 50 on the nose but its atleast 30. The torque numbers are probably alot lower too.
Down 5mph in better weather is quite a bit tho.

Strange things happen and cetain combinations just don't work. The ls6 and ls2 intake runners both flow the same with the big difference being the 90 mm throttle body.You would think a head&cam motor would benefit from the larger throttle body as the new 400 hp ls2 motor works well with the 90mm tb and is only 364ci.

If they do in fact flow the same 'as-cast', that just means that the LS2 intake is less efficient than the LS6 per its size. We all know what velocity does for torque (ie: AFR's 205's vs 234+cc fabbed factory heads, or high velocity merge collectors vs wide open 3" collectors). The opening is larger, but the runner inlets are a tad smaller. My guess would've been GM was aiming at more low-end. They did step up to a 6L. But, things just aren't adding up here as more low-mid probably would've help @ the track...

On the dyno the torque did not peak untill almost 5500.
I wish my scanner was working and I would post it up. That would probably help.

This is driving me crazy!
I just sold my LS6 intake to buy an LS2.
Louis, are you still hoping to have some more comparisons by the end of this week?
There are going to be a lot of disapointed people if the LS2 intake turns out to be a dud.

I really hope for everyone who has bought them that it is not a dud.

Just got of the phone with wayne at MTI. New numbers with LSX90,90TB, 85mm MAF, kooks 1 7/8, and new cam. I pushed 400rwhp and 380rwtq before. We just got 441RWHP and 403RWTQ. This is A4, Vig 3800 stall,12-bolt with 3.73 gears and heavy ZR-1`s. Not bad for stock bottom 346. We sprayed it with 150 wet shot and got 650RWHP and 660RWTQ. I can`t wait to see how she runs!! MTI are as good as it gets!!What do you think fellas!!

The cam is bigger than my X1. David and crew want to annouce the cam so you will have to talk to him on the numbers. We did flycut the pistons. You should here it, Sweet. When I get her home I will video her idling and download. I just wanted to post with good tuning the 90mm stuff works good on a H/C car and loves the spray! So the LS2 should do well.
