I think Imo000 (Imre) ran a 12.4 with his DIY S/C 6 psi setup with a 5 speed and stock manhole covers! It is really hard to get a good 60' with an auto, they are dogs off the line with the 2.20 rear.

Brett: Glad to see you get the record, take your time setting up your new system. Get that baby into the 10's! It is a rough crowd here, I know your pain. When I had may GSXR1000 I raced a ZX-14 at the strip, both of us were newbies and I won by a fender with an 11.1 ET. I posted it on the GSXR board and I got laughed at huge, everyone said I couldn't ride and that I should be in the low 9's!

 

Hi Mark

Its the new REVO system from Wizards of Nos and its totally progressive and totally electronically controlled (no jets)

To get that 13.03 I was using just over 10% of my available Nitrous power lol...

If I had carried on then yes I am sure I could have had an easy 12 or a hard 11 but I had done enough to take the UK record and once the aircon belt shredded on that final run, I took it as a sign that it was time to call it quits...lol

I have no intention of running the 1/4 again (unless someone takes my record) as my intention is top speed runs...

I only ever ran the 1/4 to stop people hassling me about no times etc with my new Revo system...well I am now the Uks fastest 928 on the quarter, which you would think would stop them, but it has not lol.....apparently either I "SHOULD" have run faster or "there are lots of 928`s in the UK that can beat that time"

We will see lol

All the best Brett

 

Civilzations and been built and overthrown in less time than that! I thought you had a progressive controller? That should have allowed you to get much more power in the upper bands.

I did 12.6 with my SCer, and I think Tim Murphy posted 11.7 or better with 600RWHP and you supposedly have a system capable of 3X that kind of power. WTF?

I know... baby steps. But at this rate your baby is going to be 47 before it takes its first steps.

Cut that AC belt and MAN-UP!

 

Its still quick compared to 15's stock.
Yes there are other cars that are supercharged going faster but his point is not in the UK.With more nitrous its capable of going faster in the 11's

 

Brett,
Before I bought the 928 ran the Duster 1/8th mile only best of 7.06 which is the same as a 10.90-11.0 in the 1/4 mile.No supercharger,no nitrous.Just a good stroker small block chrysler 340 motor with 4inch crank(416cu in). Full interior,exhaust still on 3450lbs with driver and of course it needed a good set of slicks.No wheel tubs even the back seat was in it.Just a plain looking street car.
That ran 0-60feet best of 1.53 seconds.
0-96.7mph in 7.06seconds 1/8th mile.
This is why I am board going 14's and 9.40 in the 1/8th.
Something close to that my old street car ran today is a new 997TT for 1/4mile times.The 997TT 60foot in about 1.68 the Duster did it in 1.5's that was the best part when leaving the line.There are alot faster street cars but for something looking stock and NA motor it ran good.When I first had this car it only ran 9.30's in 1/8th mile and over the years of different combinations was almost into the high 6's in 1/8th mile.There were other heads for the car that put out about 100hp more than what I had but connecting rods were stock and would have to change those and the heads plus traction would of been a problem as with the 28" by 11" wide slicks were at the limit the next thing would be tub the wheel wells etc but didn't want to cut the car up.Its now somewhere in California think Riverdale area.
Basically the stroker motor is probably close to what some guys are bulding for their 928's.
Stock was 340 cu.in
4.04 bore with 3.31 stroke
Went to 4.07 bore with 4.00 stroke.
4.07*4.07*4*6.2832=416 cu in.
Roller cam .660 intake .630 exhaust 260 duration intake and 270 duration exhaust at @.050
Edelbrock Victor JR intake
750 holley #4779
Stainless steel Norris Rocker arms
ported w2 heads
727 auto trans case with smaller internal parts from 904 with 6 clutch pack so it
would hold up for street use but light reciprocating weight to save horsepower.
Venolia Pistons 11:1 compression ran on 93 octane pump gas because street driven.
Ran .120 wrist pins as drag cars uses .09wall and oval track used .120 which was
good combination for a street car lighter in weight but stronger than regular drag style wrist pins.
Pistons were 480 grams compared to over 600 for stock.
Auto Trans with Turbo action TC flashed at 5200(That left the line good)
The best part was building the motor back then they didn't have stroker cranks that big for the small block chrsyler.
I had it made at Moldex Tool Company in Dearborn Michigan that was back in 1987.
Today you will see the 4inch cranks in the chrysler performance parts catalog.The biggest stroker back then was 3.81 that
was used for super modified class.
Raced that car from 1978-1994 then bought the 928s4
Remember no matter how fast you go someone will say they have a friend or knows someone that has something faster
be happy with what you have as you set your goal and made it,your car runs good.

 

Take it easy on this guy he is having fun with his car, remember he drives this 928 every day. A record is a record so let him enjoy his win!

 

He did what he said he would do. Good for him. I'm sure he could do much better with the system running full tilt, but who cares.

 

13 FLAT!
That IS getting it.
nice job.

 

That is fast/quick for street tires on a old runway ! And the car still has A/C not a gutted race car. Good job !

 

My car creates a bazillion horsepowere.

Heck, I even have the fastest 928 on my street!

Oh yeah, I have the only 928 on my street.

Does that mean I have the slowest 928 on my street?

Quit picking on me.

 

Kudos. That's a decent time early in the development.

The trap speed is of course more important for your top speed objective.

Thanks for posting the time slip. It's good that you posted it. Some may think the ET/trap speed are impressive, some that they are unimpressive, but you run it and then posted the time slip.

I think there will be fewer people giving you **** here from now on.

You should definitely continue to run those tests. Don't focus on the ET, though. The trap speed though is extremely relevant to your ability to hit high speeds in a limited distance track. The 1/4 trap speed is probably the single most relevant test that you can run for your project.

Exactly.

 

12.87sec was my fastest and it wasn't easy to get it. It was cheap but not an easy road. This was on stock tires and beforwe the H pipe. Ted you should be in the 12s too.

Brett, well done.....small steps and you'll get there. If traction is not there, there isn't much you cand do.

 

Brett Awesome job! Glad to see your not afraid to 1/4 mile your car to gauge performance. Nice job on your record! Your trap speed is high at 113mph! That's moving and should be good for 11.9 to 12.1 all day long! Your gears and tires are holding you back in a big way!

Nice job!

 

Hi

You are correct, as my car was intended for top speed runs, my diff is a 2.35 and my rears are 10x18 with 285s (oversized) which improves the gearing for top speed but definitely does NOT help on quarters lol

But I said I would produce a time and ticket for all the doubters and I have...

Some may not be happy with my time/speed and say I "should" have gone faster, but I am totally happy with my UK record...

I realise that to you Americans with multiple drag tracks it may not seem much but it will do for me

And for anyone in the UK....its going to take a 12 to beat my record and with all the UK power 928s that I know, that aint happening soon lol

If it does I will happily shake their hand and congratulate them

All the best Brett

 

Hi All

Some pictures from my record run day that someone sent me....















All the best Brett
