I just came across this product and wondering if anyone had installed it on their LC. Also wanted to know if anyone knows about this company and if this product is any good - benefits, improvements, drawbacks?

$1K for an intake tube? Mark me skeptical

We've been trying to get information on this for another LC client.

Installed yesterday. Can’t say there’s any improvement other than in the looks department! More importantly, no codes on the dash.

 

When there's not data to back-up the claims, ask yourself what are you really buying. Thanks for the honest feedback.

 

I could get it back on the dyno and see if there is any difference. I might just do that this weekend or next. With the PPE headers and exhaust it made 415 HP and 388 Torque at the rear wheel. We shall see if there has been any increase!

 

^^^^^Do you have the dyno curves? What gear did you dyno in.

Lou

 

I did three pulls: fifth, sixth, seventh. In seventh gear I must have hit the speed limit as it would not go above ~6000 RPMs doing approximately 180 miles an hour on the tachometer/speedometer. 7th gear is 1:1. Perhaps there was a little more in there.

 

^^^^Thank you

Odd that that best run, fell off the cliff at 6K RPM

Lou

 

Thanks for the info @anchaf3

 

I think I hit the electronically controlled speed limit. The speedometer was reading 180 or so and the engine would not rev greater than 6000. The needle just kept hitting that mark and backing off.

 

^^^^So you used different gears for each run? What gears did you use? 7th is the direct straight through gear.

Lou

 

5th, 6th, and 7th. 7th is the gear that topped out at 6000 RPM

 

^^^^Hmm, somethings wrong. I have done 2 dyno dates when I had my ISF, both were done in 6th, the direct drive gear in the ISF 8 speed. I witnessed one with the RCF, done in 6th. The LC should be able to go to redline in 7th, unless Lexus is doing something tricky

We will see what happens when I get it on the dyno again.
