Trackhawkz06

Im going to be running full e85 and used the upgraded Lingenfelter injectors... (The stupid expensive ones).... and a low, and high side fuel pump.... along with a cam with +32% fuel lobe.... My trackhawk should be done in a week or two... and then the vette goes in to get it done!

What s/c pulley on the 2650? 8 rib or 10? Any belt slip?

Cordes Performance Racing

No slip. And the upper was a 3.5

Shoud run the fic injectors, way more reliable.

The 2650 requires coil relocation and aftermarket valve covers (or modified stock covers). The LT4 specific kits that will ship from Magnuson (about 3-4 weeks) will have the necessary cooling lines, fuel line, coil relocation brackets and a tool (template) to aid in cutting the factory valve covers if aftermarket covers are not used.

My 2015 Z06 made 728 STP corrected RWHP (700SAE) up from the stock 545 STP corrected RWHP with the Maggie TVS2650 on 91 octane only (no meth or octane booster)

Mods are:
Magnum DI TVS2650R (patent pending)
NW 102mm throttle body
GM Performance CAI
All else is stock (heads, cam, fuel system, exhaust, cats, etc)

15.6 psi out of the box?

That was with a 90mm pulley and stock lower, which is what the kit will go through CARB with. Goal was to match the boost of the 2300, but due to the different characteristics of the TVS2650R we have higher boost up top.

HNK

What would a 2300 with the same boost do?

2Highpsi; THANKS for the Info.

2650 is amazing.

2highpsi

I can't get to that boost level with the TVS2300 on 91 octane only due to the knock limit.
The 2650 runs more boost and more timing - A/F ratio was held constant between both blowers.
See Ignition timing comparison below.

Wow, 728rwhp from a blower swap and pretty much nothing else is amazing. Any idea on the ballpark this kit may cost?

$6k - check you tube Magnuson posted videos of TVS2650 !

Cordes Performance Racing

this tells me next to nothing. what is the combo, what gas.

CamOnlyJabroni

I think I’m going to have to do a cam and 2650r next year.

From the above post:

GM Performance CAI

In the "Part 3: video he says its running on 91 pump only.

Cordes Performance Racing

I'm trying to see if he is expecting me to believe it took that timing on 91 at that power level.

Good question.

More questions regarding post #45:

• Did the 1740 and 2300 blowers also have the 102mm TB? I’m guessing not by the low 1740 dyno number that I’ve seen people hit with 87mm throttle bodies. Inlet restrictions are a big deal on PD blowers.
• If we’re trying to compare actual blower efficiency and ability to make power between the 3 blowers, why aren’t we testing the 3 blowers at the same boost level? If the short block and exhaust system are the same, then the restrictions are the same to making power. All 3 of these blowers can play in this 600-700 HP range, so it’d be nice to see apples-to-apples.
• By just adding a 2650 blower, why can we now spin the short block several hundred rpm more? Did valve springs get changed too with the 2650? We know the 2300 is capable of making more power than shown above for sure if pullied correctly, so why are we stopping it short? Doesn’t seem like a fair comparison IMO.
• Just my 2 cents...maybe I’m missing something... very possible. lol

UPDATE: Spoke to Tim and the fuel pump should be shipping this week hopefully
