Hi guys back out at the creek again.

This time with 311kw at the wheels.

I'm still having a little bit of trouble off the line.

the only spot on pass i did i managed the 12.0 at 128mph.

Next time we do out we don't want anything less than 133mph.

before anyone says you won't get that, we will run another 5 psi on top of what we had before.

Also on the 12.0 we ran with 18psi next time we wil drop it to 15 as thats the pressure we ran on the last two.

one my last run i forgot to put the traction control back on, this resulted in lots and lots of wheel spin all the way down the track untill i got into forth.

as for wheel spin, yes with the traction control on it still does spin through third but we limit it with the motec.

Cheers

My guess is it needs some serious suspension work, like all front wheel drive drag cars it will benefit a lot from a decent set up. What spring rates are you running? Shocks? Camber? Toe?

Personally I wouldn't be worried about more power until you can use the power that you currently have.

:P cheers :)

The front end will cost us about 3k to get sorted where as we believe there is a good 100kw more in the power side of things.

New products wich will go onto the car in the future.

1.Hypertune billet plenum

2.Hypertune billet 76mmTB

3.New turbine housing.

4.ARC 100mm front mount

5.ELF race fuel

6.More RPM

7.More boost

I wouldn't recommend that approach. ET is king.

I 100% agree with Kenny, no use in having mph and a would of, could of, should of ET

I know with my old set up I ran 128mph and it was good for what ever ET but the best I ever ran was 11.7 so really it was a high 11 sec car no matter what the mph said as thats the best It ever did

The front end will cost us about 3k to get sorted

You don't need to go to that extent to improve the ET's.

Have you had it on a wheel aligner and looked at the front end dynamic camber change? What about bump steer? Keep more of the tyre in contact with the track surface, $100 well spent.

Have you checked the corner weights? If not, there is a good gain there for almost zero cost.

If you are not running at least 1,000 lbs per inch springs in the rear that that's a start. Lessen the weight transfer off the front wheels, $300 well spent.

There are so many simple things that you could do, I bet there is at least 1/2 second in it with a mimimal spend and a day's work.

:P cheers :laugh:

Man I have so much that I just don't know about drag racing...

This is the most refreshing statement re: drag racing I have ever read on this forum.

You're my favourite person of the week, Dan. Congrats!

:D

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
