aint gonna be no brake boosting against a tvs...same whp and roll racing is always gonna go to the s/c unless its at a mph to where the turbo'd car doesnt have to brake boost...u guys are compairing a m62 powered cobalt..were now in the tvs world..cole isnt concernd with a m62..

2K5SS/SC?

I have video back at home of a 01ish Saleen S281 supercharged racing my Integra which obviously has more displacement and a bigger blower than the TVS. My buddy in the passenger seat caught the whole thing and all you hear is the load placed on the engine from the brake boosting on the Integra, 3 beeps with the Supercharger whine right after the third beep, and then the sound of the Integra taking off like a rocket ship and putting multiple cars on it easily. My buddy with the camera had to film out the back window almost instantly after the brake was released and yes you could still hear the faint blower whine fading. Not sure what his power was, but he wasn't stock either and that was only on around 14-15psi on a small 16g.

No one will probably belive me without the video, but I am deployed right now and haven't had access to it for over 5 months now. I'm here to say that a fully spooled turbo ready to go as soon as you let go of the brake is just as fast if not faster than a superchargers initial grunt!

now we are comparing other cars.. .getting off topic here. and yes when im talking supercharger i mean the TVS or the Twinscrew. but if actually roll racing and you dont do that break boost bullshit... you will get smoked. but do what you have to do to beat a supercharged car i guess

Hahn RaceCraft

I have to disagree. ProCharger needs higher RPM to make boost, whereas our turbosystems can produce significant boost under 3000 RPM. It is for this reason that the ProCharger, and other centrifugal superchargers (Vortech, Paxton, etc), have never caught on with the 4-cylinder set...they are just much better suited to torquey V8's.

Hey man I tried to stay on track as I have raced the Cobalt against my Integra. We did it both ways and the outcome was pretty much the same. I hate to say it, you can call break boosting bullshit all you want, but when it comes to racing the one in the lead wins! A good driver will take every advantage a car has and uses it to go for the best outcome. Remember, not all people run turbos that are too big and take forever to spool either. My Integra redlines at just a hair shy of 7000rpms and has full spool by 3300-3500rpms and makes power all the way to redline. At 40mph in second gear that turbo is screaming already.

ColeJJones

like this? aaaaaaaaaaaaahhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhhh h!!!!???

THRcobalt07

I vote turbo! I'm goin with the Hahn Level V when I save up enough.

ColeJJones

can hahn level 5 run a bigger turbo?

2K5SS/SC?

Haha funny. No cookie for you mister! Go sit down in the corner!

Hahn RaceCraft

Sure! The Intercooler, piping, and manifold can support 600-700 HP with ease. But the S20G is a great all-around turbo for street use, and has delivered low 11's on nuts, 10's with a shot of N20...so be cautious about running something bigger unless you really really need to!

ColeJJones

looking for the 450 goal....

2K5SS/SC?

Hahn S20G is all over that like stink on ****! No real need to go bigger!

ColeJJones

i thought it was rated at 360hp

2K5SS/SC?

Nope, it's rated for 500hp! The small 16g's are rated for around 360hp.

ColeJJones

its the 20g and im reading the site and it says 360 but 400 with a portFueler

2K5SS/SC?

You're reading the horsepower to the wheels that they made with 60# injectors. The turbo is rated for 500hp which means if you had bigger injectors and/or a return style fuel system or the port-fueler than you could crank up the boost some more. Remember though, there will be a point where you will need to swap over to higher octane race gas to continue making power without detonation. The turbo has the ability to flow enough airflow for 500hp, which should be just fine for 450whp you are looking for.

TVS_SS

hmm if turbo is the way to go...

WHY did AUDI pick supercharger?... (yeah the same AUDI that is a very big fan of turbochargers)

im pretty sure they know 1000x more about boosting than anyone here...

Hahn RaceCraft

Well, heh, on that note...why did GM, who's put more supercharged cars on the road than any other manufacturer, now toss aside supercharging in favor of turbocharging?

TVS_SS

actually.. GM hasnt put the most supercharged vehicles on the road.. mercedes has..

also.. they havnt tossed aside supercharging last time i checked.. lol

IonFeright

...nor has Audi tossed aside teh turbo

Raven SS

simple...california emissions

TVS_SS

correct.. but my main point.. its not as one sided as many think it is..

and anyone who claims a proper sized turbo has no lag is insane.. they all have lag. reduced lag turbo's have limited power capability due to such a small size and choke flow limits..

its too bad the internet 'propaganda' has done such a good job brainwashing people with turbo's.. becase i could have a great technical discussion, but now it would be pointless.. the only repsonse i would get is.. "turbo's are free power" or just "turbos FTW"

so.. i will save my breath and enjoy reading comments..lol

Raven SS

dont worry..when u have that conversation i will be right behind defending s/c's

TVS_SS

I am a fan of having knowlege and basing opions on facts.

but, this is the internet... so.. yeah..

Raven SS

u didnt know?! brake boosting > instant boost full power lol
