-   -   Which is more effective Turbocharger or Supercharger ? (https://www.team-bhp.com/forum/technical-stuff/2184-more-effective-turbocharger-supercharger-4.html)

Hehe, dont be confused, just read the post again...

I have put down what I was told. Anyways, you might want to speak to the tuner or the owner directly, I can give you their contact numbers, PM me if youd like.

Sorry, Ive never read the definition of external modifications, pardon my ignorance. I would like to hear from you...if you may!

How do u expect me to be sane after reading this???
First you tell me that some car is running a SC and does a 1/4 mile in 15 odd seconds on absolutely stock internals and zero external mods..

then you go and give what all external mods are required.. How is he running an SC(whatever brand that is) as a daily drive without any mods..
I completely agree with v1p3r..how is he running the car without any mods and without ruining the conrods, or rings under repeated high-stress applications????:confused: .

Someone has definately played a prank on you.there is no way this car is going to have a stock engine..

Godfather

Either that car is producing 20 bhp more than stock seeing the way there is no upgraded fuel pump, injectors, conrods or the likes or the owner is lying through his teeth :D . These days you cant believe anyone. Too many people claiming my car is stock while running sweet mods.

thanks for explaining godfather had stated that the power required and also mostly used on muscle cars and few pony cars.

but this is not the case when they are looking for high hp cars like the new gen z06, srt 10,stang gt all these cars put above 900 bhp and are preferred to twin turbos and not sc even though in na form these cars have bucket loads of torque sitting with them.

these cars which i m talking about are lingenfelter,heffener,Hennessey,Pure Power Motorsports etc..

Bro, thats why I askd you to read my post again... Pls refrain from asking questions before you read the posts well.

Ask him.

Just another Honda...I guess:p


Like the way you said an Indian vtec cannot drive a supercharger is it??LOLzzz

Im afraid I couldnot strip the car to see what its running inside so I took the tuners words for it. I am not interested in performing a credibility check anyways...coz some people simply are trustworthy, that might be news for you.LOL!!!

Read my 31st post 5th line, you should get your answer!

I dont have anthing upgraded that you have mentioned, but I promise you my car is easily 20bhp more than stock. Get a dyno, Il prove it to you:)

Guess you forgot some cars come quick straight from the factory!

but this doesnt seem to be the case of top fuel dagsters. ill tell you why.

1.the turbo can reach its limit very soon.(the sc used take 1500 hp to move)

2.belt driven turbine can always push harder.

3.the sc is a 14-71 type roots sc.

4.46 pounds of boost is used at full throttle imagine the lag of the turbo.

5.You could make a turbo topfuel, but it would be very hard, expensive, unreliable, and extremely dangerous. Not to mention much slower.

regarding the vtec what type of supercharger is it using is it roots,twin screw or centrifugal.

I was talking about the SCed Vtec ritesh not yours. As you said if he is running just a street setup without upgraded internals there is a doubt that it will clock low 15's. Yes, I wish I could get a dyno though. Is the car brown in colour? With red stanley seats?

Roots type mate.


Funny cars and top fuels are a total different game mate. There again the SC's come into play due to some very similar reasons you and I have mentioned below...


No I guess you mentioned the car wouldnt be more than 20bhps without those external mods mentioned hence I quoted my car as an example, which doesnt have anything and without the SC its easily producing 20 additional horses easily... and also coz above that the connecting rods would bend etc as per you!

No, thats not the car you are mentioning.

FYI, the fastest car in india in 1.6L FI class runs stock pistons and connecting rods!!!

so its roots type they produce low range and also is he still running the stock intake manifold since these sc dont compress the air inside the sc like turbos but compress the air at the intake manifold.
wonder why he used and not twin screw because they become really hot.

Very true. But I was told that its some hybrid types, not sure what!!!

Agreed. May be price and availability for D15 concerns!!!

just googled it an this is what i found hope this helps:

Traditional roots blower design is old engineering, and admittedly is not very efficient, but engines designs from that era were not very efficient either. As engines have improved over the years so has roots supercharger design. The Magna Charger, Inc.Eaton supercharger is a hybrid-roots blower pump, with substantial design improvements. The rotors have a unique involute lobe shape and are engineered to a specific l ratio. Each rotor has been twisted 60 degrees to form a helix. The two counter rotating rotors have three lobes, which intermesh during operation. These twisted rotors, along with specially designed inlet and outlet port geometry, seal timing, and axial air flow help to reduce pressure variations resulting in a smooth discharge of air and a low level of noise during operation. This arrangement significantly improves efficiency over traditional roots superchargers and reaches a volumetric efficiency near 98%. Magna Charger, Inc. applications have an adiabatic efficiency that stays above the 50% mark over the full operating range of the engine, from 2000 to 6000 rpm.

from 2000 - 6000 is really good.some thing like a twin screw low and mid range.

But he is not hitting his 75 shot of nitrous every day, is he?
