I have not seriously considered getting a supercharger. For whatever reason, the track times just aren't there v.s. a strong h/c car. But I run on the street and the highway. If a strong, say, 450hp h/c LS1 ran a supercharged LS1 with the same power, or even a little more, who would win in a street race, and especially the highway? I would bet on the h/c for the track, but would the street be different? And why? Thanks.

 

I can't comment on the supercharger, but I raced a Nitrous WS6 that dyno'd 8 rwhp more than me (I did 448rwhp), and I beat him by about 2 cars from middle of 3rd to top of 4th gear.

If I was spraying on top of that, he would have been destroyed.

 

Usually the H/C car would win.. No boost to wait for and usually the H/C car is lighter as well..

 

H/C? What does that stand for? You guys and your abbrev. <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />

 

Heads/Cam

See thats why you got to go with Heads/cam/and a blower... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Thats where the combo really starts to get you power... <img border="0" title="" alt="[Smile]" src="gr_stretch.gif" />

Stock, no heads/cam with MAC headers and ATI D-1SC I ran:

At the track: 10.98 @ 125.83 MPH

On the street, I beat two big-block 454's and a Nova with a 400 CID, runnning heads/cam.

Remember guys he said cars of equal hp.. That being said the H/C car wins hands down.. Unless we are now figuring in driver error... I raced a 505rwhp SC'd car on the street from a stop that had 3.42's. My car at the time dyno'd 419rwhp, but I had the cutout closed so I am going to say closer to 405rwhp.. I have 4.10's. We raced 2 times and he did not catch me until we were over 120mph from a stop.. A well setup H/C car of equal power will dominate the SC'd car from a stop to about 140mph. Maybe past that the SC'd car will ride out.. I think a turbo car would display different results secondary to the massive tq at lower rpm, but that was not the question..

Tq can also hurt you.. If you cant get traction. Guess what? You are not going anywhere.. Remember the parameters that he said.. Do not add to the equation..

 

I guess I should have asked a different way. Option 1: Get a good h/c package, like the Cartek X. All the boltons, tuned, basically wring all the power I can out of it. Option 2: Get an ATI, all the bolt ons, stock bottom end. Wring all the power out of that, but keep boost level safe. The dyno isn't a big thing, I think an ATI would dyno much bigger #'s, including tq, anyway. Who wins on the street/highway? BTW, I would love a turbo. But I don't think I could install it myself, unlike the other two options. And I don't want to lose my headers.

 

If you are talking about from a stop and all being equal when it comes to horsepower and tires. I would have to say that depends on the gears of the H/C car. If we are talking about from a roll of above 50mph.. The SC'd car would have the advantage if the right driver is behind the wheel.. Now if we are talking about SC'd car with 4.10 gears against H/C with 4.10 gears.. Then I would have to say the SC'd car if the SC'd car can hook... SC'd cars like gear as well. It gets them up to max boost faster..

 

I don't understand how someone would do FI tho without doing all the bolt-ons including a Cam and Headers. Heads are expensive and a waste for FI.

That's where the difference is. FI, Cam and Headers vs. Heads/Cam. I know that wasn't the Q, but I never would have gone with an SC without the above mods 1st. Also, SC & Gears. End of Story vs. H/C.

Maybe even molest the original post further and say.. Is the labor and cost of expensive heads worth the power gained? Esp vs FI SC?

 

Mellow you are starting another dispute.. Lets start another thread about your SC with cam and headers comment. I agree that with gears the SC would rule.

 

No doubt. To much TQ on the street is a bad thing. I raced a Turboed stang that made 500RWHP/600RWTQ to my D1 equipped 92GT with 400/450lbs. The HP difference was bc I had stock heads,cam, and intake. No need to mention the TQ difference. The race was nose to nose until around 100. He just couldn't make that extra TQ work. As far as SC vs. heads/cam, I say heads/cam. Ever notice that they run #s equal to SCed cars with 50less RWHP? Is it the driver?? I've always wondered myself. Even Mustangs are plaqued by this. In the same 92GT, I ran 11.40s/119. My buddy's 92GT with all motor almost same weight ran 11.40/117 with 30 less RWHP. We both were leaving at 5000 and powershifting. His 1/8 time was 3ths quicker though.

 

The reason I asked the original question is because of the type of racing I do 99% of the time. I cruise along the road, someone pulls alongside me and we punch it. On weekends late at night I prowl the highway. The E.T.'s of supercharged cars (in general) have never impressed me. But the mph has. Like a Supra with 600rwhp that runs a 12.50 at 140. I may beat it on a strip, but I would get crushed on the highway. That's what I'm looking for, and that's why I think an ATI may be good for me, because the the MPH they run on the strip tells me it may be a good setup for racing from a roll. And I like to race very fast. 140+ <img border="0" title="" alt="[Big Grin]" src="gr_grin.gif" /> If a supercharger has the advantage, I want it to be big to justify the loss of reliability (i.e. blowing an engine).

 

bravo you are righ, mph is what wins street races, and FI has it.

 

My buddy has a 2002 TA w slp headers, mcleod clutch, stock rear,and a borla catback along with his ATI D1sc kit.

We raced from a roll, and it was really close. His car put down 460 some rwhp while mine was about 407 at the time. I pulled a little on him....

For the street I would def go heads/cam....but that's just my 2 cents. I was looking into the ATI kit but am in the process of building a stroker instead...for my application it was more economical in the long run.
