I know this has been talked about a lot. I have read some older posts.
I am deciding between Whipple and VMP. What would I need with Whipple 2.3 or 2.9?
What would I need with VMP and what kind of numbers can I make without going crazy on a new fuel system? Thanks guys

Removable elbow...

"Removable", not the easiest with a GT500 TB bottom bolt it as PITA. I'm really interested in the new Whipple 3.0, not that there is anything wrong with my Gen 2 2.3 but I feel I'm leaving a little on the table. That said if you're not upgrading the fuel system and going E85 don't see anything wrong with getting a used Gen 2 on the cheap. What fuel system you running now, stock?

stock fuel system and I would like to do a E85 tune to use it every now and then

I’d had both a Whipple 2.9 and VMP 2.3.
Here are my thoughts: Whipple has more room to grow. It’s not the best blower on pump gas- you’ll really to keep it on E85 as it’s a big blower that takes a lot to spin. That’s not to say it’s not fun on pump, it’s just a big blower. It’s a fun blower that just keeps pulling and pulling. You can get around 600 rwhp on pump @ 16-18 pounds of boost on pump (that’s really the limit on pump IMO). I was at 820 on E85 on 25 pounds of boost.
The VMP 2.3 generally (from what I’ve seen and heard) has more torque and puts out crazy numbers for a smaller blower. It’s a more than capable blower on pump and it’s really fun. As Roy noted, the removal elbow is really a plus.

It’s really just comes down to what you want. E85 and cheap don’t go well together. To upgrade the fuel system expect to spend some coin. What kind of numbers do you want? Does your car have head studs? Plan on dragging the car? Need to have clear goals and guys on here can steer you in the right direction.

Knowing more what you want to use the car for will would be more helpful. A 2.3 on pump gas making 600hp will be a lot snappier then a 2.9 at 600hp on pump gas. The bigger whipples leave your room to grow and you can always pulley down keep on making more power. My old 2.3 tvs was spun up to 21/22psi and I put down 730rwhp on e85 and it was a very fun street car but I felt that little guy was at its limits. For my next build I’m going with a bigger blower so I have the room to expand and grow.

Really I'm not racing it or anything like that. That street driving. I would like to be around 600hp. I thought that the VMP was a 2.6. I'm really looking to do plugs, 60#injectors, single blade, ba3000, boost a pump, heat exchanger, expansion tank. I'm not too sure about a lower pulley. I would like to also do an E85 tune but not to use all the time, just every now and then

Gen 3 and up are 2.65 the Gen 1 and 2 are 2.3. Honestly my 2.3 is plenty on the street for just screwing around (well over 700hp) but I have a bunch of other stuff done. If 600hp is your goal 2.3 would fit the bill nicely for all around broad power band IMHO. In that case E85 probably isn't needed and don't know if the system will support it even with a stock fuel system and E85 even with a BAP and 60's.

Where you gonna get a 2.3 tvs these days? Shouldn't even be in the conversation imo...

In the market, for cheap, possibly mine shortly. IMHO the new bigger blowers are a waste for 600hp when you can do the same with any of the 2.3 blowers at half the price on the used market. Judging by OP goals and budget better off with an older gen blower and putting what he saves into a proper fuel system then a shiney new blower with a boost a pump on 16+ year old stock pumps. Might not have the same room to grow but plenty of guys making in the 700 range with a 2.3 and E85 but going to need pretty much a whole fuel system at that point.

I don't see the stock fuel system - even with 60's and a BAP - being able to flow enough volume to support E85 or any 93+E85 blend. I'm running 60's and a JMS BAP and she's cranked all the way up. If E85 is the goal, you'll need to bite the bullet and beef up the fuel system. No way around it.

I'm new to modding and everything. What would I need for a fuel system?

Lethal Performance makes and sells several different kits. This is right in @c6zhombre 's wheelhouse as he's all about "grazing the corn fields." lol

I would never run a twinscrew on 16lbs. Thats just insane. The peak hp number on a low boosted twin screw means nothing. Not saying you did it and you hit the nail on the head on big blowers need boost. There were ported eaton cobras with a upper lower pulley comob staying side by side backinthe way with a 2.2 kb on 15 16lbs of boost. on 93, if you have a 2.3, 2.6, old 2.2 kb, 19lbs is the sweet spot.

I don't even remember twin screws I installed on my cobra. and I did experiment with the 15, 16lbs. That was with the 2.4 kenne bell when it came out. The car felt like total shit. worst combo I have ever had on my cobra.

If your not going to race it, or have the need to make 700 800++ rwhp in the future and just want to have fun on the streets, just get a small 2.3 blower. You can buy a 2.9 whipple, run it on low boost, pump gas, make the magical 600hp, but, I will bet you, it will not perform like a 600hp car and you will lack so much low end tq you will hate the car. If you have a built motor yea you can run the 2.9 on pump gas. On a stock motor, this blower needs boost. I run 22lbs on mine. I will never run it any less. I don't care what the internet tells me. Id rather go back to a ported eaton if I pulley down. Thats just me.

Well said, @stangfreak. This is why folks were asking the OP what his goals were. Those goals should determine which blower and setup he should consider. I would say based on what he is stating he will be doing with the car, your advice on a smaller 2.3 with higher boost would be in his best interest.

The new blowers don't act like the old blowers. I made 600 with my 2.9 starting out. It acts like a 600hp car. It still seems pretty snappy. Even on the 91 tune at 18psi.

That being said I'm currently tuning on E85ish and going to be getting a smaller pulley soon. But even the starter tune was a ton of fun.

As mentioned if a fun street car is the goal stick with the 2.3/2.4. Buddy has a 2.3 and loves it. Simple enough set up and will walk 90% of what's out there.
