curious about upgrading my magnacharger

[FullsizeRST]

a freind of mine out here called magnacharger up and they said the knew latest and gratest was to up grade the tach addapter out of a corvet along with the throttle body the chang out the intake tube for a larger size one from magnacharger you could see gain from 30 to 45 hp. if you allready had a cam swap and a custume tune

i was wanting to this and was woundering if anny body else has done this or heard out it?
here is what im talking about

Dude Ive Never Heard Of That But If It Gives You 40hp-let Me Know Too BTW HOW MUCH BOOST YOU RUNNING?PULLEY SIZE?

I think you are talking about upgrading the throttle body and J-tube to a 90mm setup.

Yes people are doing this and yes they are seeing nice gains with it.

[littless]

they are talking about the TAC module correct Throttle Actuator Control. i know i have seen someone on here selling the J-Tubes i have been looking at doing this set up for a while but lacked the funds but now i have them but can't find the J-tubes or is it just easier to mod your exsisting one?

Leave the tac module and just buy this
Torque Rush LS2, LS7 to LS1 throttle body adapter harness
and an LS2 throttle body.

Then get your jtube upgraded.


Chevrolade, you just need the ls2 tb and jtube, no harness needed.

yes you can get the larger j tube from magnacharger

it goes with the larger throttle body there for you need a larger j tube rather than porting out the existing one

i am running the stock pully size because i know like three guys out here that arent and they kkeep on craking pistons etc...

and yea im sorry they calld it the tac addapter

i will call lingenfelter where i got my charger from and talk to them about this more

also there is a corvet salvage yard about 20 min from my house and they have all the parts i need just not the j tube

when i call i post some pricing up about the j tube

I did this. I am assuming your throttle body is DBW?
You want an LS2 Corvette 90mm TB, the 90mm Magnuson J-Tube and the TorqueRush module. Do not swap TAC modules.
The gains may not be 30hp but they are noticable up top. I did this mod in addition to upping the shot another 25 and dropped .3 in the 1/4 mile.
I would it's say a worthwhile mod.
