Thread: VVL vs. T25 question

Dollar for dollar, a T25 setup would be cheaper and make more TQ on the low end.

Keep in mind, while it is cheaper you are adding more variables and weight to the mix.

Like you said Chris, it comes down down to what you are doing and how much you have to spend. With a $2000 budget I would say the VE still gets the cake for overall performance and reliability. Less weight, broader powerband, killer response and less shock on our fragile drivetrain.

No bias here as I am both a turbo and NA guy.

Like i said a broader powerband will win up to a point.

So what is rolling and wind resistance going to require. Just like to get a car going initially, torque is being used for a moment then hp takes over.

Wouldnt the same apply with wind resistance and rolling resistance. Wouldnt the torque be used in this situation to overcome that?

Again at some point the extra 70 ft-lbs of torque from the turbo car is going to be used correct.

Again how else would you explain a 210whp ve and 210whp but 210wtq turbo car taking less time to get to 140+mph. You say its the hp but both cars being the same as far as gearing and tire size and so on. Explain this, the Hp VS Torque thread was useless in answering this question. Too much conflicting crap.

I like this idea the best !!!

Ashton I'm going to move this over to the HP vs TQ thread so we can continue.

Both of these setups cost about the same.

DE, S4, T28, 370 4bar, bored maf, 3" exhaust, JWT
VE, 16ve cams, Fuji Header, HKS 60mm exhaust, Calum ECU

Someone show one point in the dyno plot where the VE is superior.

Well that isn't a stock de w a t25 either. Let's see my ve vs ur t28 graph but I get ur point totally...

Yeah, I could drag up a T25 dyno plot, but it's still a super budget friendly setup. The only difference is the T28 is another hundred or two, and though I had a Greddy EBC, the same thing could be done with an MBC.

And if we're going STOCK for STOCK, nobody in their right mind can make the point that a STOCK SR20VE setup will outperform a STOCK Bluebird/Avenir.

Let's go real world though. Once you boost a DE, or install a VE, more mods will undoubtedly follow, and just adding a boost controller gives you more hp & torque than a whole bunch of parts thrown at a VE.

Edit..

^Exactly I see your point Chriscar but that is not a super strong VE setup. Also T28/S4 is a kick-ass combo. Your point is fair though.

I still like both setups and most of my SE-Rs are based all or in part on one of your builds so...

I tend to prefer turbo because of the massive low end torque. With turbo I can be in 2nd gear driving around town and if I need to gun it to quickly pass a car, I don't need to down shift. With VE I would have to find a way to shift into first gear (which isn't advised or even possible on our trans unless your going 5mph), to be in the power band, otherwise 2nd gear is too slow at lower speeds.

It all depends on your purpose. Auto X and Street = Smaller turbo, Drag strip = VE/Big Turbo, Track = depends on how many turns there are and how many straights.
