Cat is Out of the Bag - 2.85 Upgrade

[Mean Cat]

I decided to finally do a 2.85 TBA Machine pulley ( Thanks to Todd owner of TBA Machine for a great deal ) , F1 1000cc injectors ( Thanks to Keith owner of Fuel 1 for a great deal ) & have it retuned. After the Track Rental day a couple of weeks ago & my best time was 10.241 on stock boost, I figured that I have just about got the most of stock boost with my set up & I wanted a little more to run 10.0's & maybe high 9.'s so here we are. The install went pretty smooth after watching a lot of different vids on it & @Speedy's vid on his install, good info !
Got the retune yesterday at Peitz Performance , job well done to Alex ( owner & tuner ) & the whole shop !
It's a Mustang Dyno which will show a little lower readings vs a Dynojet Dyno, but it made 732 hp / 688 torq. - 93 octane tune. If we don't get rained out this Friday ? I'm excited to see what # it will run at the track , to me that's what really matters.

Isn't it funny the $ we'll spend just to see different #'s on that little piece of paper?

I hope all your upgrading goes smoothly and the car just flat strolls!

Thanks , & yes it is , but considering that I did the labor , the total cost was $933 ( pulley , injectors & retune ).
I'm done with it at this point, I don't want to push it any further & will be happy with what it does now.

Look how purty the underside of that S/C lid is... 'Damn near eat off of it...

Congrats on the upgrade, the install is really pretty simple once you get in there. I've not heard of the TBA pulley but it appears to be decoupler like the Litens?

Thanks Speedy, the TBA is not a decoupler pulley , it the hub is octagon shape , as well as the pulley & does all of it's driving force with the hub center on the pulley center , the 6 screws just hold the pulley on the hub, hope that made sense. I went with TBA over the Litens or Metco pulley bc of cost , design & I already have my lower stock damper pinned.

It would make a good ice cream bowl.

Really nice looking. That's the factory snout and elbow, just with the new pulley, right?

Famous last words. Lol

Yep makes sense. I like the decouple setup on the Litens to keep pressure off the blower when you shut the throttle, but lots of folks run fixed pulleys no problem as well. Glad to hear the crank is pinned. Cheap insurance.

9s here you come.

Thanks & that's correct.

FYI , I don't know if anyone else has had this issue but the shop that did my tune was showing me they have had several Litens pulley failures , where some snap ring had broke or came out & the pulley would walk back into the snout , so just keep a eye on that ?

I've heard one report about something like that. Litens asked for the pulley back to do an analysis and (from memory) something was done incorrectly during install. Also, they I've seen they now include a spacing washer so I assume some of the blower snouts that are cast aren't all exactly the same. I was told to measure mine after install to make sure I had 2-3mm between the pulley and the snout. Mine was on the close side at 2mm but was good. I bet some hit the snout at install and that might be what the shop was seeing. Mine's been on there a year with LOTS of WOT hits. Probably in the hundreds at this point The pulleys the same design as OEM.

It’s about time your balls dropped 😂

OK , good to know that, I haven't heard of issues with Litens pulley until the shop mentioned it, so prob. some difference between each snout or one of those fluke things ?

Well I guess I am just waiting on you running 9's.
Then I can go out in spring and feel slow.
Great pics. I can't believe how clean the blower looks compared to the one they took off my car.

Well I guess some drop sooner than others , but as long as they drop we're all good !

I just wanted to see what I could do with stock boost b4 I did any more. I think it might of had a little more in it with low humidity on track day but we hardly ever get low humidity down here on the coast , so it is what it is.

Thanks Jim, maybe with great DA it will run 9's but I don't expect it to be the norm.
It might be so clean bc it only has 6900 miles on it & in March I will have had it 3 years, lol.

Don't forget your still fast too !

Everything on mine was coated in oil. Mine had about that on it when they changed the blower. The mechanic had no problem with installing the spacers when he saw them after seeing all that mess. LOL
I just do my thing and have fun.
I have to give my track lots of credit for the fast part. I can line up and confidently nail it 99.99% of the time. The track usually only gives up near the end of the day when they stop keeping up with it.

Not exactly one off but something folks need to be aware of. Cast parts aren't all that precise.
