BLKWS.6

Does anyone have a before/after track pass in similar weather that shows the increase in trap speed a lid GAVE YOU? Anyone with dyno numbers?

Sorry, I am trying to keep excited about getting my first mod. I am not being able to shell out $100 as soon as I would like due to having to do other things maintenance related and figure I would gather info on its hard gains in the mean time.

Just save that 100$ and wait a month and buy a dry kit. Then you will have noticeable power increases for 2.5x that price.

Just put it on and be done with it. Enjoy the new engine sucking sound and be done with it, thats about all you'll notice. Not saying there's no gain, but its not significant.

I could definitely tell a difference on the interstate with mine and the K&N.

mine made a decent difference but hey,100 bucks for atleast 5 rw,that is a bargain. i dynoed 319 rwhp,34x rwtq lid only and the car trapped 88.8x mph in the 1/8th.best mod when i was lid only was a set or tr6 plugs and a nx 150 wet shot that gained exactly 150 rw.

i'd consider a lid more of a supporting mod, not necesarily big by its self, but collectively it makes a difference...

I gained .1 in the 1/8th with a lid. I don't remember what the trap speed gain was, probably a solid 1mph or so.

SladeX

Bone stock lid
308ft/lb 295HP

No lid (still had the air silencer on)
315ft/lb 298HP (gain across whole torque/hp curve, not only peak)

SLP lid
LS7 Clutch (9lb additional rotational weight, -hp, -torque that you can feel)
LS6 Intake

325ft/lb 306HP (gain across whole power band)

308->325 Net gain of 17ft/lb, 295->306 Net gain of 11HP

To gain HP and torque despite adding 9lb of rotational weight lends a lot to the combined gains of the intake and lid. I think the no lid dyno is what really shows how restrictive the stock lid actually is. Help the LS1 breath, get it a lid.

My CETA put down 340 RWHP and 360 something RWTQ with only a lid and slowmaster. It has been a best of 12.8Xs on Nittos. Sorry I don't know what the car ran bone stock

When I got my direct flo lid...I could feel the difference up top.

I ran a buddy after putting it on and could definitely tell the faster I went.

I believe I picked up almost 1 mph
