well would you???

 

Centrifugal blowers don't work well on small engines IMO.

 

last time i talked to vortech they said the type-r kit was gonna be around 5500.00, i can think of better ways to make power for less than that.

 

I've talked to Vortech about this and they are developing one that may be released in the next 8-10 months. They had to finish the GSR one first.

 

for that type of money , i prefer having built a 2.0l N/A with nice gains to 220whp

 

FI

 

Only if it came with a scantly clad **** strapped to it.

 

Turbo

 

Hell yes. The Vortech charger is no joke.

Supposedly some guy is making like 225/155 on a 99Si w/ just V-AFC and exhaust.

 

i remember seeing a pic of a cw itr with a vortech sc on this board. i think it was a vortech sc for a SI, but they did something to make it work properly.

 

Whats our compression ratio? Isn't it something like 11:1? How could you supercharge that without tearing it apart and putting in new pistons?

 

I drove their black si before it was stolen. At the time, it had their SC and that`s it. Stock exh from the block back. It was pretty quick, I was impressed

 

usitr 10.6 j-spec R 11.1

 

for one superchargers suck...
but I would get a JRSC before I got a Vortec

 

if its cheap~ yeah, maybe i will get it~ but more likely its gona be $4000~5000

so, i might just go NA and building up my head and button

 

Actually they blow, NA sucks.

Vortechs are dyno queens. They put good numbers down but the Si's still seem to run low 14s right with the JRSC cars which have 50 less hp.

powerband and use able power, id get a jrsc before even thinking of the vortech!

but ya, keeping it strictly n/a r0x0rz !

I agree with this statement, then again, JRSC suck *** too.

 

whats the difference between the JRSC type and the Vortec type, in terms of power delivery? anyone know?

hey mike, i think i saw another dyno, most of the power band isnt too much different from the JRSC...except the last 400-700 rpms, where the power band spiked... (creating the 380 hp civic) .. but again, it wasnt much usable HP, just max HP.

I have mixed feelings about this one...

No mixed feelings here turbo all the way

 

Here's a compairson of a Vortech Si and a JRSC type R that put out almost the same peak power.
Si with a Vortech charger:

type R with a JRSC charger:


Look at the trq!!!! Now you tell me which one you would want. The Vortech setups have way too big of a charger to make a good bottom end which makes them suck for that reason alone. Our little 4cly need that bottom end to get going. With the Vortech setups, once you make the trq and power, you have to shift and build it up all over again.
The only Vortech car I'm impressed with is the top speed dragger Vortech Si which hits over 200+mph with a crazy setup.

 

Roots vs Centrifical, why would you want a roots? They create more heat for your intake charge, and are very limited on how much boost they can put out. The vortech can put out some good boost, but we can't use it unless we drop our compression.

Even if I won the lotto, I'd still keep my R NA. ITB's and spec C's baby

 

Its simple.
If you want a Supercharger, go with a JRSC. If you want a Vortech, go with a turbo kit

The Vortech is a cool kit, and definitely adds a ton of fun to the Si, but its more expensive than a turbo kit, and lacks the respective advantages of a turbo kit or a roots SC.

 

IMO it comes to all around performance. So many people here are so concerned about their peak power or max power that they forget about the whole picture. I still don't see why one would want so much power! The average NA built R setup will yield anywhere from 190-220whp. The average JRSC R setup will yield anywhere from 190-230+whp. The average NOS kit will do anywhere from 190-230+whp. The average turbo setup will do anywhere from 230-350+whp.
Currently I'm at around 250-270whp with around 160-180trq. I love the power however the downside is that the front wheel drive system has its own limits. With my power I can't hook up in 1-3rd gear at all even with A032R's. When I downshift I will spin the tires and I also get tons of trq steering. I have been able to manage the power and make use of it by tuning the power curve around by giving more top end or reducing the bottom or top end in area's to give more power in other spots.
What I don't understand is the need for so much power when you can't even put in on the ground on the streets. Our cars are very light at higher speeds so thats not a real good argument and our cars will spin the tires in the lower gear with anywhere from 230+whp.
Yeah the vortech is cool for its crazy peak power, however wouldn't you want more low end?
I think the peak power thats totally useable on the street is around 230-250whp with the right adjustments in the curve to keep it balanced.
The main reason I went with JRSC is because it gives the feel of a REALLY strong NA setup. The power is totally linear which is great for our cars and the trq curve is flat as a NA piston dome. With the Vortech setup all your getting is a crazy high top end power jump. Kindal like having a NOS system kick in right before redline. The power is totally not useable. The only real way to make the Vortech work good is to increase the displacement and drop the compression to allow for more boost. By doing this you will get the low end pull and power from the larger engine and you will get a stronger top end from the boost, etc... However this huge power will just spin the tires on the street. It sucks. Say you were a street racer which most of the power hungry people are. Wouldn't it suck to not beable to or just lose to people because you can't hook up at all. Kinda sounds like the american guys that we make fun of. However I'm not one to talk since I loose traction also. However I'm trying to get the most out of my setup to prove a point to myself that my money that I spent on the JRSC isn't waisted. Also I want to see the max power of a JRSC with a stock internal engine. Once I find that I will be able to then drop certain area's in the power band to give power to other needed area's to make the car more efficient.
Anyway thats just my opinion. I know alot of you people drag as I do and need the most power and I don't knock that at all. However it just sucks when you can't put that power on the streets.
People need to keep in mind the balance in power, weight, traction, etc... that Honda had done to the type R's and other Honda's. Their is a reason why we don't have that much power stock. The more power you add the more it will take away from traction, handeling, weight/power balance, etc... Rememeber to keep the car balanced. If you add a ton of weight in the back with stereo equipment, you better add some weight up front to keep it balanced. Same goes with power. If you add a ton of power, you gotta enhance the brakes, suspention, adjust the weight, etc... If you don't do this you will loose the overall balance of the car. I know this because I too once messed up the balance and had to fix it the hard way. Yet now that I have it all fixed and balanced my car is a million more times thrilling to drive.

Please take my comments as comments alone and not as attacks on others or put downs on others. Its mearly a theory I have found in my car that has seemed to work for me and I feel that it might help others.

 

Here is the link to the ITR with a vortech supercharger meant for an SI.

the owner has had problems with the car though.
