Will the V-7 JT-B mount to the same bracket as the V-3?

Thanks!!

 

Yes sir

 

So much for that excuse. LOL

Thanks!

 

lol!! You can pretty much run any vortech or paxton in that bracket.

 

except for a Novi 2000 and Novi 2500. Needs a different bracket but those are pretty much phased out.

 

Ya I definitely have seen those units used in the last 9-10 years on C6's. Pretty much anything Vortech or Paxton modern day will fit. They are mostly the same units with different case designs now.

V3TI/1500SL
JT/2200HD
YSI/2200R
YSIB/2200X

 

yep, I’ve had a Vortech SI, TI, 2 YSI’s. Paxton Novi 1500, 2000, 2200, 2500. All work differently for different purposes.

 

You should definitely look at some of the other units that are out there now. I have run Vortech V3TI, V1TI, 2200HD, AFI91 and now I'm on a ESS G3R. If you not brand loyal to Vortech you should look at Procharger with the A&A bracket or Ess with A&A tensioners/idlers. Self contained units with higher max impeller speeds. Lower step ratios so you don't have to run baby pulleys on the blower to spin them. D1X is killer on a LS3. The G3X and G3R are sick. My G3R pours boost on crazy fast without being overspun.

 

Not so much brand loyal. More that I already have an A&A bracket installed and running good. Plus changing the bracket increases the cost.

The V-7 JT-B looks to be a new(er) design and will a billet impeller and to be a step up from what I have now, a V-3 Ti with a redesigned/improved billet impeller. Guess it would be a Ti + in the scheme of things.

I want to see what it can do with a 7L vs a 6.2L. Maybe it will be enough.

I've looked at the ESS site a few times. No information for the G3R, no compressor maps, no apparent support for C6.

 

The JTB will be a nice upgrade over the TI. Higher max impeller speed, Oil fed, HD case and bearings and larger shaft. It is a race blower.

The cost of the JTB alone is more then the cost of the ESS head unit with brackets, hardware and spacers. Ess sets up the brackets to use the A&A tensioners and idler pulley from your kit. The G3X would be the equal to the JTB. Both flow 1600cfm. The G3X is lighter, self contained, no fancy oil, has a higher max impeller speed and a lower step up ratio. Say you want to turn the JTB to max impeller speed 65k at 7000rpm. That would require a 3.0/10%. Doesn't sound like much but on most 8 rib setups on a 3.0 upper you will likely get belt slip. On the G3X you would run a 3.50/10% to get max impeller speed 70k at 7000rpm. The G3R is more on par with the YSI-B/2200X with cfm. Ess gears their units more towards coyotes but that's also what Vortech geared the JTB towards. If I planned to stay with the OEM GM LS3 block I would have gone with the G3X but I knew the LSR was in my future. Which should be fired up this weekend. I ran the G3R on my forged H/C 6.2 and it was nasty. With Centri's its all about how you are setting the motor up. What rpm you plan to turn and what you will need through the mid range. A lot of people get hung on a peak dyno number or boost number.

 

Interesting info, thanks.

Do you have a compressor map for the ESS units? I sent an email to ESS.

The engine is a 427 with 11.375:1 static. Built for E85. If I can't get E85 I turn the boost down.

What does "ESS gears their units more towards coyotes" entail?

LSR? What displacement?

 

I do not have compressor maps. Have run all the different units I have a pretty good idea of what one will do and what I need it for.

What's the power goal, intake manifold and power goal?

I think its how they cut the wheel for air and rpm, inlet and outlet size based on engine size and rpm

My LSR is a 388

 

It is at 750 WHP on E85 now with the factory 6.2L and factory intake. The SC is limited to 9.5 PSI so there is some boost left.

New engine is 427 CI, 11.375:1 for E85, FAST LSXR 102 with medium runners. 230 INTAKE / 245 EXHAUST 116LSA 112ICL 0.609LIFT, 2" headers.

I don't have a hard and fast HP goal now. I should be able to hit 900+ WHP, maybe closer to 1,000. If I change the SC it would be to get to 1,000.

 

Looking at this combo staying with the V3TI will be a good option. In reality it should make over 900whp. The Fast intake is not designed for boost and is not recommended to see more then 15psi where most of the larger units will want to make well over that. If you slow them down they will just be lazy. People have done pushed the intake beyond 15psi it but its really just pulling the pin on the grenade and will end up damaging parts. It will be playful and fun. Traction will be a nightmare.

If you decided to go after the "fast" later I'd make some changes. The cam is small for a 427. 427 will make ground pounding torque so you will want some rpm to help you get to a traction point. I'd also change the intake for something boost friendly that will turn a little more rpm and peak at a higher rpm. Resleeved blocks are pretty stout so I would look at the G3X or even the G3R. Just depends on how much you want to make at that point.
