Vortech Supercharger Installed!!!!!

[07g35coupe]

thats awsome

[07g35coupe]

have you tracked this thing yet

[kmech_7]

you do NOT want to use a shot of NOS in a supercharger setup.... the only time you use it is for cooling the intercooler air.

I have taken this 'thing' to the track and i am putting up about 8.1 on the 1/8 mile.

[USAF_G35_Guy]

yes it can run with the E55 amg. the benz goes from 0-60 in 4.5. mine goes in about 4.1 or 4.2........

i know that in the 1/8 mile i get 7.5-8.0's all the time.

and yes im pushing about 405whp. 475ish at the crank if i did the calculations right.

so what's the 1/4 time? and let us know what the actual hp is after a dyno! 405whp sounds nice tho! If you're getting that then I'll definitely go SC!

Supercharge is better for a road course/curves due to the power being in the whole RPM range.

Turbo is better for straightline/highway/open tracks

If this was true then F1 wouldn't have used them in the past...and WRC wouldn't use them currently...and 90% of the factory cars that come with f/i wouldn't have them. A correctly set-up and tuned turbo system will have almost no lag and full power can be had at any rpm while with a s/c you have to wait till the rpm's are redline. Also a car with a turbo can very easily be modulated with throttle as it is with a s/c system. F1 banned turbo's back in the 80's b/c motors were making way to much power...bmw's 1.5L 4-cyl was making more than 1500hp...they never got an exact number b/c the dyno's didn't go high enough for it.

For drag racing...yes the s/c is better off the line b/c of instantaneous response and power....but for maximum power and efficiency the turbo is better....

In reality both are better than being n/a, but to each their own and budget, legal worries such as CARB, and other factors will woo a person to one form of FI or another. But just so you know the vortech is basically a belt driven turbo system

Btw...not to thread jack....I'm very jealous of your setup there my friend...looks very nice and I bet the power increase is amazing to feel in your pants...NICE JOB!

Actually I've seen good numbers with someone that had a vortech and 75shot...The Vortech makes most of its power in the upper RPM band. If you hit NO2 just after the 60' mark, you'll be significantly quicker because your power band will be much wider!

What you're referring to is meth injection...which is a waist of money IMO.

I prefer the Supercharger...

Uhh? This is a huge myth. First thing I'll tell you is that regardless if boost is available at all RPM's, the winner of the race will be the one that can keep the most power to the ground at all times. This means, that even with a supercharger, you still need to keep the RPM's up by remaining in the lowest gear possible to take advantage of the torque multiplication. This renders low to mid RPM's useless on a road course. If you are halfway decent on a race track, keeping a decently matched turbo spooled is not going to be hard. Before you cite turbo response, consider that when you exit a turn, you make a gradual shift from steering input to throttle input. Short of way oversizing the turbo for the motor, by the time you are needing the power the turbo provides, it's already spooling.

The other thing you should consider is that centrifugal superchargers do not experience a level boost curve. Rather, it is more proportionate to engine RPM. So at low to mid RPM's, you experience less than the peak boost (at half the redline RPM, you would get approximately half the peak boost pressure). By contrast, even a moderately sized turbo will reach boost threshold by the mid RPM's and still have enough steam to keep it going through redline.

[joe603]

I don't know why they don't have high boost superchargers that bleed off excess at mid to high RPM levels...so if you buy a 9PSI system, it makes 9PSI at mid rpm range, just like a turbo...then release anything over 9PSI. What am I missing Chano??

[C-Kwik]

C-Kwik, what do you think?

I tend to be biased towards turbos myself. However, if I were looking at a kit, I'd be a little reluctant to go with a turbo as they have had much more history of blowing up motors. I'd speculate that this has to do with the nature of a turbo being independent of engine speed which requires more tuning parameters. Superchargers will be much more predictable in airflow and boost since it is tied down to engine RPM, so less consideration has to be made towards planning for early spool, or an overboost situation.

If reliability is a big factor, then I'd go with a S/C. Personally, Stillen's S/C would likely provide the most ideal power curve for most, but the hood bulge would be a huge deterrent for me.

I think if I were to make the choice right now though, Turbonetics turbo kit would be my first choice. Turns out they are now offering an optional limited supplemental powertrain warranty for an extra charge with any of their kits.

[Jacko3]

C-Kwik:

If the hp in turbos come all at once, while that of SC comes in gradation of RPM, it would then seem as though that Turbos may create more stress on the transmission and engine than a Supercharger. The gradual rise in boost form a SC, dependent on your RPM, should be safer than an immediate surge in energy. So, one would expect a re-inforced transmission system using a turbo than a supercharger. What do you think and what are your thoughts on this?

[Jacko3]

In addition, I am of the beleif that someone willcome up with another performance part that will increase horse power only slightly without the use of a TT or SC. Or, the price of the SC will fall to a reasonable level as a result of market forces of demand and supply. In the next year or two, something good is bound to happen to the prices of these equipment. I think the prices are very high. I shall sit and wait to see if they drop. In fact, I was offered a brand new Vortech Supercharger for $4700 in January 2008, with no taxes or shipping fees. I didn' have the money so, I declined.

[joe603]

Don't hold your breath...I had a 97 formula LT1 firebird that I was looking to put a procharger on...the price never budged at around 4k.

[C-Kwik]

Engines produce torque. There is no other force that an engine provides. Engines do however, transmit torque over a broad range of speeds. HP is a calculated figure that is based on torque and engine speed:

HP = (torque x RPM)/5252

There is no sudden rush of HP coming all at once. It doesn't somehow add up over the power band. Think of it this way. Put your car in first gear and accelerate to redline noting how fast it accelerates from 4000 RPM and up. Then compare it to driving along at 4000 RPM and flooring it. You'll note that the accelerative forces in both cases will be the same from 4000 RPM to redline. In other words, if you ran your car on a dyno in the smae way and plotted each, you should find (outside of errors inherent in dynos) that the actual torque curves will be the same after 4000 RPM. You could do this with any RPM and it will always be true. So the peak torque load that any transmission will see will be no more than the peak torque the engine puts out (not including dropping the clutch from high RPM which involves flywheel momentum).

That said, turbos have a slight lag response versus a S/C when going from a closed throttle or part throttle to full throttle. This actually means any shock loading from instantly opening the throttle would be less in a turbo than a supercharger. However, the shock loading from opening a throttle quickly pales in comparison to a drop clutch launch or shift. So it's moot in either case.

i think they jacked my thread....lol

What kind of mileage are you getting out of the G with the Vortec?

Put the $$$$ in an IRA or 401k plan.You'll thank me for the advice in 25 years

LoL I have been doing this since i was 18

I have built up about 30k in my IRA and about 12k in my 401k lol

And it is thanks to good advice like that, I will be so well set at 40 it won't be even funny!

I still want a SC lol

- the stupid... I started at 20 though.

If you can live off half your salary for 20 years you can live off the interest for life. My new fav thing to do is day trade stocks with Scott Trade... I only have about $6k to "play" with but I made just over $500 in January

lOOKS GREAT JUST ORDERED MY TUNER POLISHED KIT. DID THE TUNER KIT CAUSE YOU CAN DO SOME AFTER MARKETS AND GET MORE POWER OUT OF IT. I WILL ALSO BE PUTTING IT IN MY SELF HOW LONG DID IT TAKE?

[Beancooker]

Awesome. I have to say I wish I could do that. Saw one in Phoenix last March that had the Vortech in it. It was the car that made me want to get a G35. Well, seeing that one, and getting to hot rod Greg's (AZhitman) all the way to the airport and back to pick up Torry.

[TopSecretVQ]

Hawt dude!

I agree with Joe..screw workin with header lol..I've already got aftermarket so I might as well keep em and go SC. I think I just may have to do this instead of ST. I've been thinking about all types of FI for awhile and definitely don't wanna do TT cause IMO...it's just more stuff to go wrong. So, does anyone know how a SC does with a 50 or 100 shot of NOS?

I have been reading a lot about the vortech and spraying. I also did a little more follow up with a local G and Z shop in Orl and they are throwing a 35 shot on the front mount getting an extra 30whp when you want it and haven't had anything blow yet. This is the set up I'm doing they also have done a 50 shot but only two runs went really well. I would build my motor going any higher then that.

[kmech_7]

i hate when people kill my thread.....lol

thanx bud!

Careful who you show your car off too!! Too many haters out there bro!!

[AZhitman]

Kevin -

Did you remove the front bumper?

What was the hardest (most PITA) part of the install?

What gauges did you add?

Have you tuned it yet, or are you running the "stock" Split-Second settings?

I'm planning to do my install this weekend, would love to mooch some info from you!

[G_whizz]

I would email him Greg...he goes MIA from time to time..

[kmech_7]

hey greg, I did not remove the front bumper but, if i were you i would just pull out all of the foam and crappy palstic in your way. i have to say that that is probobly the biggest pain in the but. that and the uptube coming back from your intercooler to the MAF sensor. For now i just have some cheaper gages but if you just want to do it once and have the cash use autometer or defi gages. I have tuned it and i recommend going to someone with a lot of experiance doing so. i went to Tim at Speed Force Racing. the thing about the SS(Split Second) program is they run there maps off of timming which sucks. At speed force they run it off of boost. this is a better system this way and gave me a lot more ponnies if you wanna call me go ahead and i can get in depth of what to-and not to do when installing.
