Is there any video on youtube?I can't save that video.

The funny thing is only a 9 sec 3/s and GTR seems like a slow car. All other cars spins tires and shift so many times and make tons of noise. lol Did you keep your old cat back system?
It's hard to tell from the video but I think I still see the same mufflers. Your car gained a lot with just a screamer and cams.

You should gain even more as soon as you put the race exhaust on.

HELL YEAH. Congratulations for putting together such an impressive build and tracking the beast. Amazing setup!!

And the fact that you ran 9.8's on Z rated 18" street tires makes it more impressive! Switching to the ET streets should cut around 4/10th I bet off your 60ft, that should put you in the lo 9's.

Again congrats André .

If you want a idea were 153 mph can get you with a ~1.40 60 ft take a look at this 6 yr old post of mine.

Thanks guys.

The exhaust I have run for the last 8 years was always custom, changing bits as required. This year I have a true twin 3" downpipe into a 4" collector into a 4" through pipe, to twin 3" exit pipes with a muffler on each. We had a 101 db limit last weekend. This will change for the Jap Drag Series where we have a 120 db limit and I will run twin 3" pipes un silenced exiting just behind what is my passenger front wheel.

I did change to screamers and custom cams but also went solid internally shimmed lifters too.

I would guess that it weighs around 3300 lbs with me in it right now. We didn't get time to fit those cf doors

for the next event, I can't run them either but with the exhast mods and wheels and tyres, I think we will get down to around 3150. The class minimum weight is 3192 so I might need to add some ballast.

As an aside, I got Tein to re-valve and re-spring my rear shocks to 8kg springs with the fronts at 9 kg

The dyno sheet says you reved it to only 7k rpm. with solid lifters you'll have another 1500-2000rpm to go specially with the dog box.

Here you go Andre's 9.89 second @ 153 mph pass at TOTB XII - YouTube

Yeah, as soon as Ben saw it wasn't making more power he let off. I really wish he would continue so I can see where my shift points are but bear in mind the guy had just pulled an all nighter to get my car running! I think we can forgive him eh? I'll have a word with him when we re-dyno for the side exits. The only way it will continue to increase with more revs is with more boost / timing.
