I'm loving my TVS

 

is the tvs a direct bolt on or do you need adapter plates and such

 

direct bolt on to our manifold with slight modification to the MAP sensor.

 

Seems to me like alot of trouble when you can just bolt on a TVS. I know you need to modify the MAP but it's about as close to a direct swap as you going to get . What area is the whipple so much better than the R1320? CFM or efficiency?

 

good question, I don't see it being better in either area.

 

what mods to the map do you have to do

 

You have to grind down the side a little so it can be twisted so the blower will clear.







Those are pics of how close the tvs is, thats why i was saying it mat not be possible.

 

I Want A Bigger Blower!!!!!!

 

thanks for the info, something to look at.

 

no problem

 

Despite common belief and talk, the TS and TVS excel in very different areas.
If we want to get very technical here... the 1.6L twin screw at full boost will push more CFM and be more efficient, hand down.... but there is a down side.
The twin screw is always compressing... it uses power at idle and while cruising to turn the blower, unlike the TVS.

 

true but with a good bypass valve, the power used at idle and cruising can be less then 1hp. stated on whipple's site.

 

ok.. please show me an isentropic efficiency map for the twin screw...

The fact of the matter is, VERY few know how to read an isentriopic efficiency map and understand what it means. People are still under the belief the twins screws MUST be more efficient. This has not been the case..

on an alternate note, I have yet to see any 2.3L Twin screw make 950+hp... yet the TVS R2300 (2.3L) made over 1000hp..

Please show efficiency maps when claiming anything becuase 90% of the time they just listening to what Kenne Bell, Whipple, and other twin screw manufacturers have to say... which of course, is in their favor

Also, a bypass valve cannot relieve internal compression.. and 1hp at idle is ALOT of power

 

I think very few people even know what an isentropic efficiency map is...I leave physics and thermodynamics to much smarter brain housing groups

 

I know we discussed this back in the day... and I know your hard core TVS
I still stand by my reasons that the twin screw is far more effeicent above 20psi than the TVS is.
I've asked Opcon for the true maps on the 1.5, 1.6, and 1.7L screws... and they are indeed far superior at the top end.

WRT the comment about the bypass, it is true that it takes 'very little' power to turn during cruising, but I assure you that Kenne Bell is out to lunch on that one. According to Opcon, it's 1-4hp depending on the pulley your using. Remember that a twin screw compresses in the rotors, unlike the roots type blowers.

 

Iono, I am pretty disappointed with TVS from what I seen and driven, let down.

 

I've ridden in a car with the TVS. I was neither let down or disappointed.. I actually opened my mouth up real wide once the pedal was to the floor.. It sounded like one of the big roller coaster rides right when you go down a Huge Vertical Drop..

SHHHHWOOOOOOOOOOO -headback- SHHWOOOOOO -shift- -scream- -giggle- SCHOOOOWOOWOWOWO.

Just like that.. I may be off a couple showoowow's.

 

race gas funny things happen

 

better flow, then upgrade blower...

I think area47 is going that route but still in the flow stages. (could be wrong)

 

what route am i going?

got a map i can use? cause im lost

 

 

lol, get a garmin, i hear those things kick ass.

 

well heres a huge bump for u.

http://www.whipplesuperchargers.com/...sp?ProdID=1162,

Model Displacement Max Continous RPM Max Peak RPM Max CFM Max M^3/HR Max PSI Peak VE Peak AE
W100AX 1.6 Liter/rev.......18,000..........................20,000.. ...........1120..........1902.............30...... ........99.............81....

those are the specs. i'd try and get something going but unfortunatly no more cobalt for me what a pooper. maybe someone else can get something going.

 

back from the dead again, is this going to come out or what? More options is great, but I'm still sold on the TVS.

after all, the TVS is basically a factory upgraded supercharger.

 

hell i'ld buy this one
