I have a 2003 GMC 2500HD with an all stock 6.0. I purchased a Magnuson supercharger direct from them based on my year/make/mode and my mechanic and I think they sent us the wrong one. But there's a lot of conflicting information on the packaging materials and the difference in throttle body setup. The outside label on the main box says 04-06 (SKU 02-19-60-000-BL), the packing list says 03-06 for the BOM description wiht 07-08 Radix listed in the part breakdown below, the instructions say 07+ 4.8 & 5.3L, and this supercharger is designed to mount with a 4 bolt throttle body whereas my factory throttle body and intake is a 3 bolt setup. Searching a few different websites including theirs it seems the MP112 (01-12-60-001-SL) and MP1900 (01-19-59-983-BL) are both listed to fit my truck.

Anyone have any experience with this? Really bummed to run into this hurdle, just wondering if this supercharger will still fit or if I should be calling them first thing Monday to send this one back for a whole new kit?

Thanks in advance for your help.

 

I believe you just need an adapter plate for the OEM Throttle Body as the TVS1900 is designed to use a 90MM TB.

The TVS 1900 is more efficent than the MP112 style blower. What they don't tell you is that the rotor packs for the MP 112 have been discontinued from Eaton.

You will be happy once you get passed this small little detail.

 

Good to know, thanks! Would the supercharger justify a 90mm and the x-link or will I get everything out of it with the 78mm?

 

Check you box, most come with the adapter plate I believe. At least the ones I have installed have.

 

Are all the 3 bolt throttle bodies CABLE actuated, and the newer drive by wire 4 bolt, or is there a different delineation between the two mounting styles ?

Does MAGNUSON actually sell kits factory direct ?
I thought they only ship product through dealers.

 

There were electronic 3 bolt throttlebodies for like 5 years.

 

Did OP find the required throttle body adaptor plate IN the supplied parts from Magnuson ?

 

Confirm, My TVS1900 shipped WITH the 3 bolt throttle body mounting plate, and studs.
We still have to fabricate a throttle cable bracket..

Having some fitment issue with the plastic OEM front grill, which does not seem compatible with the front mounted Heat Exchanger... yet...

 

Grill does fit over (around) heat exchanger, as long as RUBBER mounts are not used behind Heat Exchanger.
3.7" driven pulley, makes 6.5 psi boost. pulls strong through 6200 rpm.

 

Yes I did, apparently my mechanic is blind but it was in there....

The kit is installed and works awesome! Props to Magnuson for their quality and putting together a complete kit. The ol 6.0 is much happier now :-)
