Whipple or TVS? Lots of questions before the big buy.

[SVTdreamin04]

If you are ever thinking about E85, go with a 1000cc injector. The FRPP 80s are kind of dead because they are really ONLY good for E85...they have poor low pulsewidth control. Stock 13-14 GT500 56s or 60s are great for gasoline only fuel.

Just reading this thread, I got a lot of love for our old 2.3l tvs. We have a couple complete units that we assembled from parts, just give VMP a call.

For the HP junkies out there, I have tested all of the "small blowers", sub 3l, and the cobra will make 750-800rwhp if you shove a ton of boost into it, but you won't see GT500 or coyote numbers until you build the motor. The 4.6 didn't get the displacement, cams, or head flow of the newer motors. So as much as some people want to believe, there is no magic solution to making 800rwhp on a stock motor.

Your old TVS is a bad unit!!! I love mine. You have also raised some questions about my FRPP 80 lb injectors. I have thought that they may be a contributor to some of my minor issues with my tune, surging after the car runs for a minute or two and the car not starting as easy as I would like it to. It's just me being picky.

You make great products... The GT500 throttle body is a monster too. I'm glad I bought mine before you all raised the prices on them by a crap ton.

No, I'm not on facebook or really any of the other sites like Instagram etc.....this is the best place to find me

Same here. This place is more than enough for me.

Since you've tested them all....post up the overlay of the 2.65 vs 2.9 gen4. That would be a good comparison I think alot of people would want to see.

There isn’t a whole lot of 2.65 results out there. I’m currently in the middle of putting an engine together and I am thinking about upgrading blowers. The gen 4 2.9 seems like its leading the pack in the “small blower” market.

What size pulleys do you run? Only have 91 and e85, so I plan on running a 2tune setup as well. I don’t want to mess with the lower, I’ll be keeping it stock.

Well two factors: elevation and blower setup.

I’m on a Gen2 2.9 standard inlet.

@4k’.

Car was on 91oct 3.75 pulley at sea level for 15

Needs 3.5 for 15psi up here.

2.9 upper nets 20/21.

If I were at sea level the 2.9 upper would put me at mid twenties.

Here is a old video of my car. This combo is 2.3 tvs blower gen 1, 19lbs, headers, and e85.

I'm now running 21lbs of boost.

That's more than enough for the street, no use swapping blowers any time soon...if at all.

I agree, and it has a little more at 21lbs! Cooler temps I've seen 22!

You guys aren’t making my decision any easier (upgrading blower in the spring). I seriously change my mind weekly about going with 2.3 or 2.65. I wish VMP would put out more YouTube content on the 2.65 with the 03/04, to win me over. As of right now I’m leaning towards the 2.3 tvs.

I made 800 with the 2.65 you won’t be disappointed

I see what you did there!

What’s the max amount of boost that can be run with the 2.65. Or better yet the smallest upper pulley with a 4 pound lower. My question is relative to blower speed and efficiency. Not what a motor can take. I run a 3 inch upper with 4 pound lower and feel like there more juice left in it. Combined with the gt500 inlet. Currently see 24-25 pounds.

I run a 2.3 tvs on both 93 and e70. Great street blower with great power. I dont have dyno numbers but I assume I'm on par with everyone else running 22lbs and corn, low to mid 700s. Lights up from a 40mph roll and pulls like a train.
The right blower depends on fuel and goals of the car.
