real 1/4 track times of BBSC?

[madfast]

ok I know that 91-94 BBSC put out 366hp to the wheels...and 98-01 bbsc put 406hp. Does anybody have 1/4 mile times of any of these cars? I know ppl say it can do low 12 and high 11s. I need somebody who actually ran and can tell me for sure they run those #s.

I'm just interested in the trap speed at the end of the 1/4 mile.

Low 12s and high 11s??? Thats incredible! With bbsc the nsx will be close to the new twin turbo porsche. Just hope it's reliable.
Does any1 know if the engine cover have to be altered to fit the bbsc (t-top storage reason).

c'mon guys! none of u have run ur s/c nsx? sup with that?

I would sure hope for a mid 11's with the BBSC. It puts out a lot more HP than the TT kit does.

 

[madfast]

I want real #s...nobody? no takers? I want to see the phrase...I ran 12.xx or 11.xx @ 1xx MPH.

I seriously doubt you'd see 11s on stock boost levels, unless the car is significantly lightened.

 

[Litespeeds]

Will be getting on in the very near future and will post times when everything is all done and tested.

From what I understand, one of the primary design goals of the BBSC is to have no modifications to the engine cover/T storage whatsoever. So no, no changes are necessary.

I'm not a drag racing expert - actually I don't know much about drag racing at all, I'm a track driver - but from the look of the dyno graph on the BBSC, it doesn't look like it produces a significantly amount of torque or hp under 5500rpm...so from this I'd guess that your off the line start wouldn't be that great.

It seems like the BBSC would be a good setup for road racing, where you can keep the revs up high. On most road circuits, however, you'd probably need a short gear setup or a 6spd tranny to optimize the BBSC to keep the revs above 5500rpm. Yes? Or am I smoking crack?

In any case, I have yet to sit in a BBSC NSX...so I don't have first hand experience. I'll have to get a ride or take one around a track to get a real impression. That being said, I think the BBSC has the cleanest installation of any SC setup for the NSX...very well engineered; but, then again, I wouldn't expect anything but the best from Mark Basch!

For drag racing, I think a nitrous setup would work better...JMO...

Well I have the Bell TT kit, I dynoed at 351, When my car was running on 5cyl (blown engine) I ran a 12.3 on street tires. I haven't ran it since, so I'd guess high 11's on street tires now with the new engine. That said, I'd assume the 366 or 400+ would be in the 11's also.

HomeDepot,

Unfortunately, there are no current dyno data or graphs for the actual production BBSC yet.

It will be interesting to see what the final product delivers.

thanks guys...quite informative. But remember that dyno #s are not that important cuz we all know that s/c or turbo give about 355 hp or so. I want to see 1/4 mile times with a 3k lbs car. c'mon rx7s run low 10s or high 9s on the 1/4 and they wey about 2900lbs.

These typically have NOS, mongo boost, and a half-life measured in quarter-miles too

 

[madfast]

yes it's true but the nsx should be a more reliable engine and with weight nearly equal to the rx7 it should be quite a good performer. but I am astonished as not many of u guys have run ur car on the 1/4 especially the s/c and turbo nsx

This kind of topics has been beaten to death. Everybody has their own opinion about Drag racing. Look at the link below.

Actually, there is a production run. However, it was run on a NSX (whitey) using lower compression pistons (9.5:1). While the lower comp pistons will result in less power, the car is also equiped with headers and a tuned exhaust...

I'm only aware of one forced induction NSX around here that has broken into 11s and below, and that is SpeedDemon's bell turbo.
I would venture that David's NSX would surely run that or below as well.
However, I do not know of ANY Supercharged NSXs that have run the 1/4 in the 11s.
Peak HP is just one very small part in running that kind of time. Even with the greater (and early) torque that the Comptech and GruppeM produce, I have not seen any 11 second 1/4 mile times for them either.

Saying that an NSX with peak 425HP will break into 11s would be a ludicrous claim.
If you saw a dyno graph of Speeddemon's turbo, you would understand why he can run 11s. Hint: It has nothing to do with his peak HP. It has to do with his power curve at barely 4K looking like everyone else's AT PEAK. His car easily put 5+ car lengths on a 9lb. Comptech by the end of 2nd gear and will do the same to any Supercharged NSX I have ever been in. I watched him do it on the freeway from a slow roll at least 10 times in a row. That NSX clearly blows away any production SC unit I am aware of in pure acceleration, any speed, any RPM, any gear.

Just my observation. That turbo barely breaks into 11s and I have yet to ride in an NSX that feels anywhere near as fast as that car. So how would any of these Supercharger's break into 11s if that turbo, with an excellent driver, barely makes it.
They WOULD have to be running much higher boost. Until then, I'll believe it when I see it. I had a vette that ran mid 11s and know the kind of power and launch it takes to do it. I love all the supercharger kits, but none of them yet have the power to do it without cheating bastard tactics (drag Hoosiers). sorry.

For those of you that have had cars this fast or run with someone in the 1/4 that broke into 11s, you already understand how blazingly fast that is. It feels like someone slammed a book on your face. None of the supercharger kits for the NSX are producing that kind of acceleration yet. I will be blown away (and very happy) when I see it happen. The vette, at 3500lbs, needed 600HP and slicks to do it.

ilya,
I agree completely with u bro. do you know the answer to this question as I am sure will help answer many questions. How much cfm of air are the gruppe M, comptech, Basch boost pushing at 6psi? and how much cfm are the bell turbo kit pushing? I'd be very interested in knowing that. thanks buddy!

Regards,

Dave

The 1/4 mile metric isn't a good comparison of the car's potential unless you hold the driver constant. Check out this thread:

http://www.nsxprime.com/ubb/Forum12/HTML/000080.html

With a very good driver at the wheel, there shouldn't be any problem getting a SC late model NSX coupe (with minor weight reduction, i.e., delete spare, tools, engine cover, mats, lightweight battery, etc.) into the high 11s.

On a side note, I just did a side-by-side ride along in a well sorted 3.0L GruppeM and 9-lb 3.2L NSX, both coupes. Both cars have been dynoed and pulled 340-360 RWHP. At WOT both cars pulled similarly hard and were nicely fast. Scary fast if you're the hapless passenger. Huge difference in the throttle response though, with a major advantage to the GruppeM, which felt much sharper. In contrast the CTSC felt like it had a dampener on the drive-by-wire throttle and had to spool up to full power. Can't wait to drive a production BBSC!

<sigh> Am I typing in invisible ink? Trap speed will be the same for the same car with almost any difference in driver skill unless you go to absurd differences. Note the referrence above (by Nimbus) at the beginning of the thread.

Driver skill and average hp will make huge differences in ET. Peak hp will produce nearly identical traps with almost any level of driver skill. That's why experienced drag racers ignore traps (except as a tuning aid) and Supra guys don't talk about much else.

As you may be aware, most NSX owners aren't as concerned with 1/4mi times. The NSX deserves more than to be regarded as "...a 1/4 mile at a time..." automobile. In fact, when you get yours, you'll be delightfuly surprised at how well balanced it is for the track (road course).

-Cheers!

 

[madfast]

Oral Physician,
I'd be very happy if the nsx could do high 12s or high 13s. You need a little of power tap to get out of the corners with a power slide. I am sure the nsx is well balanced but power is important too.

Just because someone wants to know the increase in acceleration capability of a car after a very expensive modification doesn't mean the car is going to be regarded as ""...a 1/4 mile at a time..." automobile." It's VERY important for anyone who is buying a modification to GO FASTER. All of the 'non 1/4 mile crowd' thats been putting down the people who want to know need to recognize.
I don't think anyone has run the supercharger in the 1/4 because they are scared of what the result will be. It will NOT go 11.xx ...no way. Like Ilya said...many people can't even comprehend how unbelievably fast an 11.xx 1/4 time is -as well as the difference between say 13.0 and 12.5...a HUGE difference.

/B]

I'm glad someone is paying attention here. Trap speed tells the power performance of the car. ET mainly tells the performance of the driver, and mostly how well the driver launches off the start.
In this thread, we're mainly interested in finding out the power of the BBSC in the real world road environment (not dyno, we already know all the dyno figures). So, if given a legitament trap speed, we can equate roughly how fast the 1/4 time should be, the rest just depends on the driver and suspension/tire/non power related factors.

Same simple analogy to road racing: knowing the lap time of a car does not tell it's HP because it's mostly driver dependent. But knowing the power of the car can offer more insight on how fast the car should lap around the track. Of course I'm just simplifying this example. Road racing has many more variables besides power than drag racing.
