Seriously though, lets get this back on track for the thread starter. Its preference and the goals will really help narrow down what direction you go in.

I don't understand why anyone would want to make 900Hp and then bleed off the boost with a computer wastegate. Why not build a 600hp car like Call911 has and bring the boost on smooth for good traction.

As was mentioned earlier superchargers also have lower iats and alot less heat under the hood.

I don't know about the rest of you but I can't even keep a set of coated headers looking good under the hood much less the array of hot parts that snake their way through the engine bay on a turbo.

Just a couple more things to consider.

Thats also another good point.

I was always talking about on the street, which my car hooks up in 1st gear on without heating the Nitto's. The track is a totally different story. All my track runs were done with slicks, and I have been unable to net any good launches which is partly due to the fact I am running my huge 18 inch wheels up front on still and partially because of the track prep, and then some more on my inexperience with track runs with this combo. However on the street (which again is what I have been talking about from the beggining) it hooks like a champ with street tires. If you don't believe me, here's a couple of vids to proove it;

45 seconds into this one;

In the first vid you BOG THE LAUNCH really bad.

Second vid you try to launch the same way although a little harder, but you can hear it hazing the tires in the top of 1st.

If I had to guess your in the 1.9x 60ft range at best. Here is a good example of what I'm talking about. My old formula(on nittos) pulling probably a low 1.7x 60ft on the street next to a cobra pulling probably a mid 1.9x 60ft. The camera car is an awd talon that goes consistent 1.8x 60fts. Also that cobra and I have the same mph, from a roll I can BARELY pull him, less than 1/2 a car.

While you may be thinking your hooking, come out to the midwest and our 450rwhp cars would make your car look SLOW.

Because he's not using his full 600rwhp all through his run either. You can hear him pansy launch it, bog, then haze the tires at the top of first. Also in a full 1/4 run, in the turbo setup, the back 1/8th would be WAY ugly for him if it was a 900hp car turned down for the first 1/8th to hook.

Honestly, if setup correctly, anything over 600rwhp, the blower car will have a very hard time on the street vs a turbo car, even with both setup properly. Although I will say, a big tire tube car on the streets can hook with a blower setup and about 600rwhp though, but I'm talking more street cars.

Dude, I don't think you know what you are talking about. My car hooks up all the way in 1st. Someone with a stock M6 could chirp the tires if they unloaded the clutch on it, I bogged it to keep the traction. BTW, my 60 ft times on Nittos are 1.6, and I didn't even heat them. The only time 1st gear has ever gotten squirly was when it started getting really cold and the streets were slippery and I started making more boost.

Get Fasbird93 in here if you want someone else who has ridden in my car. He's railed on my car as well and can tell you it doesn't spin at WOT in 1st gear.

See the bold, that is my exact point. On that launch, your in the 1.9x range or slower.

What was your 60ft/et/mph? My car went a 10.80 at 127.8 with a 1.56 60ft.

I'm not trying to talk down on your car, it just doesn't hook all that great like your play it out to be, and it isn't 60ft'ing or 330'ing all that great IMO.

I have already said my car performs better on the street than it does at the track, and it did a 1.6 60ft time at the track with the Nitto's.

I think any car with 600+ RWHP that can be rolling 3 MPH in 1st gear and then go to WOT without any wheel spin on street tires is pretty impressive. If you think that doesn't hook all that great, go look for others that have 600+ RWHP and can hook up in 1st gear on street tires. I doubt you'll find any. If you do, its doubtfull there will be many of them. Most guys I know with 500 RWHP have traction issues in more than just 1st gear.

theres a few fast cars here that hook awesome on street tires from a slow roll. One is a grand national that has ET's on it....ran an 11.3 and hooks perfect from about 10, idk about any slower as its basically a dig race.

Also, a 670RWHP cobra that hooks on the street with hoosier drag radials

and a 575rwhp GT that hooks with BFG drag radials...

Tuning your suspension is key.

My formula made 520rwhp on the first stage when it was the heads/cam nitrous setup and would hook up pretty good on 325/50/15 mt drag radials, but thats a big difference from a nitto.

So you went a 1.6x 60ft on the nittos, thats great, what was the et/mph then?

On just the nitto's? My best was 11.3 @129 with that 1.6 60 ft time. Like I said, it has always performed better on the street. This year I plan on getting some skinnies up front so I can actually make good use out of the slicks.

Enough with me having to convince to you what MY car does. Lets get back on topic; what is it specifically that the OP wants besides just big HP?

Seems pretty pointless and an even bigger waste of money to build a car just to have have bragging rights about dnyo numbers. Last time I checked, "driving" a car on a chassis dyno doesn't give most people a lot of satisfaction. Unless you have built a 900rwhp reliable motor, most people don't have any comprehension of what it takes. And reliable doesn't mean that the motor made big numbers on the dyno just before the motor let loose, it needs to be repeatable time after time without having "problems".

Even with the ability of controlling the boost on a turbo motor, the car's chassis is in need of some serious upgrades as well as tuning the chassis in order to apply that power properly to the ground. This requires still more money, time and knowledge.

If you want to "legally" run a big HP motor at the track, don't even bother to show up without an NHRA/IHRA certified chassis car, including a 10-point rollcage, 5-point harness, driver's suit, snell 2000 helmet and a grocery list of other required safety equipment and be prepared to have your car "teched" from front to back. The bottom line is that it takes a lot more than what most people are willing to give in order to go fast on a dyno, the street or the track.

Maybe I'm just too "old school", but this whole "internet racing" seems a little out of control as it seems to bring out a lot of S*** talking about other people's set-ups. I'm not saying that this is all bad as open discussions of what other people are doing and how they got there is generally a positive. It's not about having the biggest or baddest, it's about satisfing your own goals and being smart about how you get there and realizing that there is more than one way of doing it. Just my .02

I can't believe the attention this post got!

Everybody wants to know my goals. My original goals where for a fast street car. I got into it with a stroker diesel the other night from a dead stop. He wasted me because I was dancing through 1st & 2nd. By the time I hit 3rd and overtook him I was pushing 105mph. This would be fine if we weren't in a 40mph zone on the main drag in the small town of which I live! At that point reality hit and I remembered that I am soon to turn 39 (whoever it was that said 38 is old, thanks I really didn't need that), I'm married, have 2 younger children, and they depend on my support, which requires me to have a license to drive. I was very close to losing my license when I was younger, to the point that I had a doctor schedule a surgery that I needed on the day that I was due to go to court, therefore pushing the court date out far enough that I regained enough points to retain my license. So I got into building 4X4's instead (slower=less trouble).

The Camaro sort of fell into my hands, right price, right time. My plans are now to build a fast track (drag) car. I still want it to be streetable for the occasional cruise just in case I get a wild hair. Now, by streetable I do not mean the family cruise to grandma's house. I have always had dreams of drag racing professionally. I grew up with Doug Vancil (for those of you unfamiliar you can do a search) and now I am watching him live his dream. I am at a point in my life now that I would like to live some of my dream, even if it is only on the weekends. I am aware of the safety needed to be "approved" for racing and I do not have a problem with that. I just want the best advise that I can get to go all-out racing.

Now that we sort of know your goal....
what are you looking for E.T. wise? MPH wise?

8s, 9s, 10s, 11s, what?
Also, what is your budget going to be?
