same here, except I am paying for the warranty so I might as well use it...this is a great deal though

 

ott are you guys online?

 

Does anyone here think 20 psi is to much boost for are cars?The tvs comes with a 20 psi pulley.

 

their little green light isn't on, so i would guess no...

not if the correct supporting mods are installed, or if the tune is correct.

 

I heard its a direct bolt in you dont have to change anything except tune,injectors.Is this true,the wiring be ok.

 

yeah, the only thing for wiring is possibly the TB upgrade.

 

i have built internals so i plan to run 20psi.

 

would 20 psi be safe with stock internals ? Our should i get the 85 mm pulley at the 17.5 psi level

 

I'll run 20 and see how long it takes to go, haha. shouldn't really be that big of a problem.

 

does the 80mm pulley run 20 psi?

 

Yes.

 

and is that what the harroop comes with?

nvm i just looked and answered my own question

 

It comes with a 20 psi pulley,idont know why i think that is dumb,because most people wont run that much psi it should come with the 85 mm pulley thats 17.5 psi.You should have a opition on what pully you get dont ya think.

 

Glad to see you on here man. We can make the prairies proud.

 

Why is that? the 3.1 is perfectly safe?

 

yeah, but can it run 20 psi safely with our motor stock? it doesnt get the heat which i know first hand that what ***** up our stock pistons haha. i wonderwhat a motor with a built head, anddimond pistons could safely run.

i have a ported head, with dual coil valve springs, cams, cometic head gasket, ARP head studs, diamond pistons, total seal rings, performance piston pins and clips, and custom ARP rod bolts built for more rotating pressure, and more RPM.

 

the 20 psi pulley is safe on stock internals? If so that would be realy cool id love the extra power if it was safe

 

I personally ran 28 psi on stock internals, i think you will be fine

 

2X ????

 

see above post

 

Damn ,how much power was it making. I hear good thing about you so if you say its safe im ok then ,i just never heard of anyone running 20 psi on cast pistons,that is what we have right?

 

how much should i run?

 

We have hypereutectic piston's, they are pretty darn strong for being a oem unit.

336 whp on pump gas and the 2.75" at 25 psi

the 2.5" required race gas to be run effectivly


20 psi (80mm) is a great starting point for everyone here, the tvs is a very large upgrade and will totally change the feel of your car. For most that will satisfy if any one wants to pulley down you can down the line and it's only 50~55 a pulley

 

What about the ls4 tb is it a direct bolton no wiring issues,and can i buy it from you,and any thought on the ls4.how much it would cost,thanks.

 

The ls4 is a direct bolt on, the tvs inlet was made to mate with it if you so choose. You can usually pick one up cheap online or from a junk yard. There are gains to be had with it, but it does make your throttle much more sensitive. Some of this can be tuned away but for most its more of a hassle then it is worth due to daily driving and what not. I personally ran a ported ls4 unit and picked up 13 whp and 10~11 wtq across the board. Like i said though this mod is not for everyone.
