Does turbo only benefit top end power? Because our low end is the main problem...

What about superchargers like mike diaz is working on?

depends on the turbo. A small turbo that spools quickly can be spooled up and providing boost by 2500 or so, and will provide lots of power. in low to middle range. A larger turbo that doesnt spool until 4500 or so(or even a turbo that doesnt spool unless you are spraying nitrous) will make ALOT more top end power, but will take alot longer to get it. a supercharger is belt driven off the crank pulley, and depending on the supercharger size and pulley size determines when you get the boost, but it generally will provide more power down low than a turbo.

anyway, there are many factors that go into deciding what you want. a setup with a lot of low end but not much top end(dv8) needs a 6 speed, but if you like an auto for a daily driver, go with a supercharger and a higher stall.

if you want drag racing, a lot of times a turbo will do very well, especially on a small car. if you want auto-x, superchargers with a stick are MUCH better than turbos. you dont have to spool out of corner, you just hit it and can always be in the gear and in power.

there are many different applications, and you have to study it and decide what is best for you, your car, and your application. its about 5x more complicated, so if you want to know more, aim me.

damm, thanks tyler, i'll aim you later

Why should we worry about a ton of low end power when DV8 is having traction problems with his N/A 3.5 on Drag Radials @15psi? We have FWD. The more power on tap low end will result in less of a gain than better high end. Low end torque on our cars would be nice in traffic and every day driving but will only screw us at the track. No I am not talking about the ~215ft/lb Like DV8 has with his 3.5, I am refering to the power being made by a supercharger.

If you disagree then please explain how you're going to manage that torque on a FWD legend. My car doesnt even get traction off the line and I have probably about 180wtq.

For/on a Legend? Can you show us?

He's right, im having trouble even with slicks. although i have yet to figure out what psi is optimal slicks are not helping yet, they are actually hurting my trap speed.
Take this as a grain of salt, i only got 3 runs on a ty track. Some times when i burn out the tires dont spin but the clutch is engaged and it revs out. i know my clutch isnt slipping, so i have no idea what is not engaging. i have a feeling its the diff, but i dont know. so this ends up hurting because i cant burnout. i was deffinetly spinning the tires in 1 st and second still. we'll see when i go back to the track eventually. This is so fustrating.

we need traction bars and a serious LSD.

DV8, just go ahead and throw a quaife differential in there it would never hurt

traction bars....

There is allready no room in the front of a legend, getting traction bars in would be a pain...

it would be doable, i just need to learn how fwd traction bars work and then try to build a set.

this might be helpful after you've got the concept down

There's many mods you can do to increase traction on a FWD off the line. Your car is probably stock when it comes to traction, thats why you dont get "traction off the line". Im just stating a fact that the legend low end isn't one of the strongest aspects of the car and that if turbo would help solve this. And its not like turbo kicks in right off the line -

I'm curious as to what mods there are, that i havent already used?

[sr79labrat]

This is good right? We will finally need something to enhance traction! Car goes in on MOnday! I will be gone for 1.5 weeks so I am tellin you now. When I get back I will run and dyno my car!

Peace, Kyle

Differentials / LSD
Traction Bar
Wider front tires
Downforce body kit

and if you want, a hood spoiler

You're already did mods to improve your traction, and you did state that your PG LSD increases your jump of about 50%. Im not a tuner or anything, but I know there are ways to increase traction, look at all the ricers running sub 12's with FWD cars.

Sorry if I sound ricey

 

[sr79labrat]

It would better to move weight forward and stiffen the suspension so the weight cannot transfer so much. Put a fuel cell as far forward as you can and the wider tires. What about an MSD unit, the have something that limits spark so power is reduced momentarily off the line. Just a thought.

Later, Kyle

I have the LSD, and the wider front tires. You forgot to mention slicks as a nessasary mod-have those. I have to have a traction bar fabricated and a downforce body kit does nothing for off the line traction. Wheelie bars do and im not about to put on wheelie bars on the legend.

I need traction bars, drag suspension and a true 1 peice drive shaft.

all this with 211lbft, imagine if it was turboed. Obviously the chassis clearly wasnt designed for this.

Kyle congrats on finally getting her done. I've watched her in the shop for awhile now. I know scott and andrea personally and know the shop they stand behind their work. I'm looking forward to seeing your dyno numbers. Would have liked to see the kit on a 6speed type 2 coupe but you gotta work with what you have congrats again.

Wheelie bars wouldn't work on a fwd car. They're meant to keep the front end from lifting too high into the air when a RWD car launches off the line...

You're wrong about how it wouldn't work on a FWD car...

Recognize that? That's Lisa Kubo's car...It's FWD and it has a wheelie bar...With her times, her crew and her have GOT to be doing something right...

I believe Bergenholtz was the first to pioneer this idea..

Read the second caption...
"In its original incarnation, the Bergenholtzes' Honda CRX pioneered the use of wheelie bars on front-drive cars."
