Confused on Lexus part, but I heard 430HP is easily obtainable. I know there are many threads on CAI on 4.7's, but is 18HP doable by just adding CAI and which oneis available for the 5.7?Not sure about the Lexus, but I have a cold air unit which is supposed to up it to around 400 hp.
Check the 381 HP thread
Its not precise,but generally accepted for paracidical drivetrain power loss.
18% for Standard trans and 20% for Automatic Trans
With two extra gear sets in the 6spd you might could figure another 10% on the 20%.The old 18/20% goes back to the 3sp and 4 sp auto days.
Add those back to your base HP and youll get close to 430
Until someone gets around 10K on one of these 5.7 the realworld numbers wont be conclusive by any means.
A simple cam(s) swap should do 500 rwhp pretty easily IMO.If TRD does it right .....? then the blower package will edge near 750 if they allow the psi to go 7-9lbs
Just random thoughts .......
Just do a history search on the way the Lightnings were progressivly modded and youll see where my thoughts come from.There are several running in excess of 1K rwhp for under $5K invested. Then add the 4 Link rear for another $5K and you have a low 10 sec. lumber rack:clown:
Although the NA 5.7 is making the same power as the SC 5.4, it's not going to be that simple for more power. The Lightning being supercharged already gave the very easy option of a pully swap to give big gains in power. Combine that with the fact the the fuel system was able to support sick amounts of power.
Im betting the pump on the 5.7 aint far from "plenty",SC pully aint even an issue.
As for the other .... 20% runnng thru 6 gear sets will have its effects.
This 6 speed is nearly 2.5 time larger then a 700R4 4sp.
If torque was water it would flow as you state ....sadly it isnt.
Not sure what you're trying to say in the first part. The number of gears doesn't have an effect on parasitic loss. It's only in one gear at a time, not all of them.
Do you not understand how an automatic trans converts HP to torque ?
Clearly not.....but nevermind I dont have time to break it all down.
And he dynoed it at 2900 feet above sea level. Elevation takes a toll on a gas engine.Maybe you could explain why this guy: http://www.tundrasolutions.com/forums/tundra/89474-dynoed-2007-tundra/
Dynoed his '07 at 307rwhp, almost exactly 20% loss.
I bought one a TRD unit for my 4.7 '04 but didn't install it, had concerns about it not filtering as well as the OEM. But I am willing to take the chance as I hope it will make for better throttle response and some power increase<?There is a CAI coming. Call your local dealer, part number is PTR03-34070.
I will find out in the morning what my cost is and what MSRP is and will let you guys know what price I can give thru this site.
$375 for an intake?!? I want to see hard dyno numbers on one first. The stock intake is already short ram due to the throttle body facing the passenger side where the airbox is. The only way I can see gains from an intake are by removing the restriction of the stock filter and airbox. I don't see an aftermarket tube reducing flow friction much more than stock.Retail on the TRD is gonna be $475.00 I can sell them to forum members for $375.00
