How much boost with E-Force 3" pulley?
 
Does anyone know roughly how much boost the 3" pulley makes with the E-Force supercharger?

JM10 02-07-2011 02:27 PM

I was told this by stillen:

- LS3 TVS stock pulley 3.5" = ~7.5psi 599fwhp 547fwtq

- L99 TVS stock pulley 3.875" = ~5.5psi 554fwhp 515fwtq

- 3.25" TVS pulley = ~9.5psi (will require belt change)

- 3.00" TVS pulley = ~11psi (recommended for forged internals)

- 2.75" TVS pulley ~13-14psi (recommended for forged internals

3" pulley on a front drive TVS might be 10 to 12psi or it might be +14psi. Just depends on how the rest of the motor is set up. Need to know a little more on what's involved mod wise.

Will have a cam and currently has 1 7/8 lts. I want to keep the boost to a minimum. Like 8-9 at most. L99-Ls3 conversion if that matters.

I'm running a front drive Maggie TVS with mild blower cam, Ported 243 heads (similar flow as stock LS3 heads), LT headers, 3" duals, no cats, and 3.1" pulley. I'm seeing 12psi. Based on that, I'd bet your LS3/L99 would see well over 8 to 9psi with the 3" pulley. If you're looking for 8 to 9psi, you might want to go a step bigger than the 3.0".

JM10 02-07-2011 06:16 PM

Im using the 3.25" and seeing around 8-9psi at WOT

05gofast 02-07-2011 08:28 PM

Depends on setup - cam, exhaust, heads, etc.

I have personally seen 3.25 pulley, cai & full exhaust get 8.5-9psi on hit & rise up to 11 by redline. 3.0 pulley on same set up peak at 13psi

2010 SS RS 02-08-2011 06:54 AM

Strongly suggest fuel delivery upgrades on anything smaller than 3.25 pully. JRE dual fuel rail upgrade and BAPon 3.25 pulley and LPE or ADM dual fuel pump 3.0. Also get inside and get internals done or you will be soon enough!
Rings, pistons, gaskets, bolts will all prove to be weak points.

kook 02-08-2011 08:06 AM

Dual pump, JRE upgrade, injectors are all being done. I want the boost 8-9 psi max.

Yea..what he said.

E-Force 3"pulley will system Supercharger system to between 9.5 -10 PSI on car.

I am trying to decide which size pulley to go down too 3.0 or 3.25. I have a LS3 with modified heads, cam, injectors and exhaust but have not touched my bottom end. Have you rebuilt your bottom end or is it stock.? Current psi is 6.5 with stock edelbrock pulley.

epstein 08-16-2013 02:06 PM

Just my opinion.... But I wouldnt go smaller than 3.25 on stock bottom end

You can see from my sig I did all the fuel upgrades before I went to a smaller pulley...

during the dyno run as was stated...9.5 psi....and when the rpms approached the limiter...was just shy of 12 psi.....

My next step is forged internals on stock displacement. Along with a JRE Cam Package and a 3" pulley.

I appreciate the advice. On your change to a 3.25 pulley did you need to change your belt? it would seem on a ls3 the std pulley is 3.5 so a upgrade to 3.25 may not need it but knowing ahead of time would be great.

epstein 08-17-2013 11:05 AM

Yeap had to change the belt.

Do you happen to have a belt number you went too? or an idea on how much smaller of a belt I should be asking for?

Hope this thread isn't too dead by now...

I'm at 486rwhp and 467rwtq on a Mustang Dyno, my current set up is:

L99
Edelbrock SC w/ 3.5" pulley (upgraded from the 3.875") (w/ the 52 lb injectors)
Borla LT Headers
Cat Delete, resonator delete, straight pipe to flowmaster mufflers
AEM Cold Air Intake
Tune

I want to break the 500rwhp mark, hopefully it can take some easy mods to get there?

will the 3.25" pulley be too much PSI for my set up? unless anyone else can tell me some easy & not so expensive mods to go with to get me to the 500rwhp range?

My overall goal was originally 550rwhp, but i'm trying to avoid having to put a cam in and i don't want forged internals... but if that's the way, then that's the way, so i've dropped it to 500rwhp.

Try a ported throttle body and then retune . It should get you close to your goal. It will actually make the car feel more powerful with the better response also

epstein 10-12-2013 11:54 AM

your prolly almost out of fuel and injector........Id make sure before you push anymore.....I dont even see a bap on your list...

The TB issue - i've searched and searched... the snout to the Edelbrock SC is same as stock from what i've read and getting someone to port it is hard to come by... i've been told by one shop that they have an adapter they make for it, but that seems like putting an adapter on there would defeat the purpose? they estimated 10hp max gains + retune came out to be some $900-$1k for a few hp just seemed too much.

The last tune i had i inquired about fuel and they said my fuel was fine when they were running it... told me not to waste money on a fuel upgrade until im closer to 550rwhp+

When building mine I came to the issue of the TB, you are correct that it is same as stock. Very thin at that with no room to port. It is however very rough inside, we smoothed it out and who really knows if it gained but we tried.

I'm running a 2.6 pulley and am around 14lbs, I am also at 5500ft above sea level.

sscamaro 10-16-2013 12:32 PM

As you can see from my sig, I'm running the E-Force with the stock pully, ported TB, ZL1 fuel pump, Jannetty fuel upgrade kit and 72# injectors. At 546/rwhp and 522/rwtq. Before the fuel upgrade kit, ZL1 fuel pump and the #72 injectors I ran out of fuel at 6500 rpm. After the above fuel upgrades fuel wasn't a problem anymore.

Bump

hiddenangels89 04-11-2014 05:52 PM

took me a while to get back on here. I've compiled a list of things i believe i need (if this thread still gets any attention). I'm trying not to go the Cam route to get to what i want, so hopefully someone can chime in and let me know their educated thoughts.

1. JRE Fuel Rail ~ $200
2. ZL1 Fuel Pump ~ $300
3. ADM controller ~ $200
4. ID850 injectors ~ $750-$1000
5. 3.25" pulley ~ $50
6. Belt ~ $25(?)
6. Tune ~ $400

With those upgrades, I've asked before, but feel i need to ask again, will a 3.25" pulley be ok to run with stock internals and such on the L99?

Also, anyone know what belt size I will need for the upgrade?

Ret Fuzz 04-11-2014 06:16 PM

well you are persistent.... a lil slow ... but persistent :)

You dont need the fuel rail.... But I would suggest the fuel line mod.
youll be fine with a 3.25 pulley but I would suggest to stay safe add meth.
Ill get the belt size ....
