How big is the lower pulley for that kit?

If you go back to 6 rib you will need:

Stock balancer $35
Blower snout $250 (I think, it could be more)
Blower pulley $140 (I think)
Good belt tensioner $90 minimum
Belt $45

That's the bare minimum. You may be missing idlers or something too.

Do this. Figure out what size lower that is they're trying to sell you. And find out what size 6 rib upper pulley comes with that blower to make 450hp at 10-11psi. I will be able to tell you how much the Steeda kit actually makes then.

Worse case I can make you an upper pulley so you're making 450hp. You wil have spent less money than going back to 6 rib and you will have a belt system that's 100x better.

That would be awesome if we can coordinate something to keep me in the safe boost/hp range.
I emailed Steeda back in regards to the pulley size for that lower pulley. Hopefully they are willing to let me know. I'm just waiting to hear back.

So from what I've read and from your wisdom I think I want to stay with this 10 rib set-up as there are lots of positives. The fact that I will have a better set-up and will be more cost friendly than going back to a 6-rib set-up.

The fact that I have Comp Cams Mutha Thumpr cams, BBK shorty headers, Bassani catted X-Pipe, with A Bullet Axle back would in theory lower the boost level as well while maintaining the power correct?
Sorry for all the questions but I am new to the boosted world. If I had of just bought this Whipple kit new it would have been way easier! Lol. $$$

I found all the below information from the Mustang 360 article that is basically my application but an automatic. It has then Gen 2 Whipple. I'm unsure if mine i the 1 or 2 version?
http://www.mustangandfords.com/how-to/engine/mmfp-1001-2007-ford-mustang-gt-steeda-10-rib-blower/

The stock balancer pulley checks in at 6.5-inches while the Whipple blower pulley is 3.5-inches. The Steeda pulleys feature a 2.5-inch upper and a 5-inch lower, (11-13psi) which bolts on to the Steeda balancer. Using a calculator, the pulley ratios are different with the Steeda pulleys spinning the supercharger faster (Whipple's 1.85:1 versus Steeda's 2:1). That meant the more aggressive Steeda pulleys would turn the blower faster at a given rpm, resulting in more boost down low and upstairs.

The Steeda 10-Rib set-up produced 479rwhp with the 11-13psi kit. The 6-Rib set-up made 459rwhp.

I'm thinking this should be mostly safe. I won't be racing my Mustang at the track or drag strip. Just for fun as it is my summer car.

I myself won't run over 450rwhp and 6,000rpm. And I'm going to do it at the lowest boost possible. You can make 450rwhp with 14lb of boost. But your tuner will have to kill the timing a little to get it done. Then you have the extra boost which means higher IAT's for no reason.

I can easily make you an upper that will spin the blower at your desired RPM (11,150rpm) which would be 2.7". But that is assuming that your stuff is all stock. With your mods that 11,150rpm blower speed could get you 475rwhp. Or 495rwhp. What you really need is a few different pulleys so you can tune it in right. Who is doing your tuning?

Dasilva Racing in Toronto would be doing my Dyno tuning. I've heard from a few people out my way way here along with some members that they are awesome!

Also this is what Steeda replied to my concern of "safe power" and estimated boost/power with my current mods;

Yes, you will have around a 2psi drop.
I have installed this setup on stock 3v motors without any issue.
You should get around 450-475 at the tires with this setup.
You will need a fuel injector of at least 52lbs/hr and more fuel pump.
We normally use the drop-in Walbro setup - Walbro Mustang High Performance Fuel Pump Assembly (2005 GT) - See more at: http://www.steeda.com/walbro-mustang-high-performance-fuel-pump-099-tu281hp-2/#sthash.LakoTi8g.dpuf

Dyno tuning is required for your setup, of course.

Thanks,
Rod

So with this said it looks like I would in theory be at a max boost of 11ish psi or lower. Sound right?

Also the seller said he is looking for that lower pulley for me as the shop took it all apart for him. Fingers crossed.

 

[Department Of Boost]

I wouldn't run over 450rwhp.

Steeda won't buy you a motor if you launch a rod. What do they have to lose?

Is that where they got the term hot rod? Lol.

Would you be able to make me a lower 10-Rib pulley as well in the event my seller can't locate that 5" pulley I am suposed to have? Or is that one more challenging? Due to how it mounts.

Was just looking at the fuel injectors and the part # is Fuel Injector: 0280158060, 4G7V-B5A. When I look it up it comes back as 36lbs. I thought Whipple sent 34lbs?

The FRPP Whipple I had came with FRPP 32lb injectors. The 32lb rating is at 39.15psi. The injectors are capable of working with much more psi and this in turn allows them to support far more hp than a 32lb injector should be capable of. They will support over 470rhwp provided you have GT500 pumps and your tuner has cranked the delta psi at higher loads like FRPP does.

Are these the injectors that came in your setup?

• OVERVIEW
• SIMILAR PARTS

• 32 lb/hr, 4-hole, high-impedance fuel injector with USCAR electrical connector
• Original equipment on 2005-2006 Ford GT

INJECTOR NOTES:

• Medium length injectors are for use in GT500 or Ford GT. We also use the MU32 in our 3v supercharger kits.
• The long injectors are the more common length and are applicable to all non-GT500 Mustangs since multi-port injection was introduced
• Wrong electrical connector for your application? Try our M-14464-A8 Fuel Injector Adapter Kit
• Need help determining which injector you require for your application? Refer to EFI Tech Tips

About electrical connectors:

• The USCAR connector is sometimes referred to as EV6, which is a Bosch term for the generation of injector.
• Jetronic is the older style connector, sometimes referred to by the Bosch generation EV1.
• Neither EV1 or EV6 is technically correct because those generations of Bosch injectors could come with either connector. However most EV1's commonly seen use the Jetronic connector and most EV6's use the USCAR connector so it's easy to see the connection.

Stock pump with a bap probably isn't going to supply enough psi for those injectors to support 450rwhp safely. I don't know for sure.

If you get bigger injectors make sure they are the mid length just like the ones you have.

These are an excellent replacement. I've run them with a dob kit and they work very well. https://performanceparts.ford.com/part/M-9593-MU52 They are also pretty reasonably priced for what you get and what they are capable of. $250 US on ebay brand new.

Aren't the ones I have (36psi)a little bit more flow than the standard 34's that come from Whipple?

 

[BruceH]

Aren't the ones I have (36psi)a little bit more flow than the standard 34's that come from Whipple?

The ones you have (red stripe) are exactly the same injectors that come with a Whipple 3v kit.

Here's the thing I've been trying to explain. Those injectors flow 32lbs at 39.15psi. Sure, they will flow 36lbs at 60psi. They will flow even more at a higher delta psi but you have to have enough pump (you have a stock 255lph pump with a bap) to make that happen.

Just looked up the calibration sheet on frpp. The offset is showing a multiplication factor of 1.1233 at 60psi.

https://performanceparts.ford.com/parts/ics/m-9593-mu32.pdf

So, if your pump setup will support a higher delta psi like 60 lbs (remember that you will also need enough to overcome the boost) then they will flow 36lbs.

Say you are pushing 9psi of boost, then the pump will need to supply 69lbs to overcome the 9psi in the manifold in order for the injectors to flow 36lbs.

Like I said, they will support over 470rhwp on gasoline with a GT500 dual pump setup. I don't think they will make it with a stock pump and bap.

They might, I'm only guessing at this point. I can tell you that I've run those injectors with a stock pump and non intercooled Whipple and we ran out of fuel pump at 409rwhp. I didn't have a bap though.
