still the same turbo as before?

 

Good to see you too frayz - its been a while

Cheers Peter - I was surprised as hell to be honest to get my best ever vpower result on a tight new engine especially as it is really my 95 ron running around map so has next to no ignition timing in there and little boost so was expecting 450 tops. 497 bodes well for adding some proper fuel and proper timing.

Yes Adam, the same turbo as before.

 

Atleast its addressed the "less than clean" engine bay issue

 

Too right, very impressive !

 

Car sounds fantastic too

 

Not from inside it doesnt lol - noisey as **** in there

The engine has done 250 miles now and feels very revvy even though it must be still pretty tight. I will drop the oil/filter this morning to get some proper oil in - Millers CFS 10/50 is what I use. Quick bolt check under there and then seal it up ready for action.

A few remaing jobs:

- fixings for bottom of rear screen
- some more permanent fixings for rear diffuser
- geometry set up
- wire dccd into syvecs ecu and set map up to control that
- bleed brakes
- clean it

Happy days.

 

Some pics

its erm an engine bay:



you can just see the end plates on the front splitter to block off the airflow from the front wheels and to create a high static pressure area on the side of the splitter (it also looks neater):



You can see the rear lip spoiler on the boot here:


and here:

 

Congrats Duncan

The intercooler pipes look sweet,think i'll get mine done

See you Wed!

Bern

 

looking good dunc

why the lip aswell??

 

Hay Duncan some brilliant results for 95 ron mate....did you change the compression ratio by any chance?

Cars looking superb and definitely liking the subtle aero mods....good luck with getting ready for the event mate!

 

That is mainly for TOTB for the top speed runs - it was getting very light at Marham for the 30-130 day at 180mph Hopefully this will keep it a little more planted

 

looking good Duncan , just gets better and better , good luck next weekend

 

Nice figures!

If you are now attaining 497bhp at 1.5bar on VPower, utilising an ignition curve for 95ron fuel, it would appear something has drastically changed since the previous spec, so what is it?

 

i would defo think that 497@1.5 bar on v power is defo possible shaun as i got 467 on v power on a fp green turbo which is slightly smaller than the 321v and 321v has a better compressor map imo.
very glad to see it running again, think i might have to purchase a 321v for one of my scoobs soon.

 

Cheers Daren

Piston to head clearance has not been altered and aside from any minor differences in piston crown cc there is no increased compression. Cosworth and Mahle pistons have pretty much the same design in the crown so cant be much in it.

RCM induction instead of APS CAI so maybe a slight improvement in airflow there.

Welded up a couple of holes in the exhaust that were probably not helping.

The run was done in 4th gear again as usual so that I can compare like for like with my previous runs at Pauls.

 

Car is looking stunning mate ,even my mrs has commented " who is the lovely scoob?"



Duncan will you be running it pre TOTB?

 

Thanks

Yes mate - Time Attack at Cadwell this coming Sunday which is my main focus.

Pretty much all ready for this now

 

Going from the APS CAK to an unrestrictive large cone will have given potential for tremendous gains. Some years ago I went from 417 bhp with an APS CAK to 434 bhp just for a change of induction tract and a big filter and 451 bhp following a remap. All measured on the same rolling road (G-Force) within a ten day period.
The APS CAK is only intended for semi standard cars and becomes a restriction and increasingly so beyond 350 bhp. The filter is rated by K+N at 309 bhp for naturally aspirated application.

 

Duncan had already uprated the filter on his APS induction to a large flat oval filter much much bigger than the APS supplied one. I seriously doubt the improvement has come solely with a change in filter.

 

Paul i think it was just you and your engine building tips to Duncan that may have swung this one lol

Dont forget to change the "Solaris" in your signature btw.

 

Yup, I recently made 477hp at 1.3 bar on V-power with a 2.35 I've been mapping, so Duncan's results seem credible.

 

Absolutely

and for the gems of information, guidance, loan of some specialist tools and patient tuition I am very VERY grateful

 

Obviously paid off Dunc.

 

Huge thanks to Paul today for doing a fantastic job on the suspension geometry. They were miles out .. but now they are flinking awesome ! Rails seem to be laid out in front of me to drive along. Cheers for also resolving the braking issue I was having too

Should work well for Cadwell.

Aside from a nut and bolt check - and last minute checking of the map the car is ready for Sunday

 

All the best! I hope it goes well for you!

 

Cheers mate.

 

All done, clean, polished, fueled and ready with a day to spare

Will get some good pics from Cadwell and some video from outside the car - didnt have time to organise in car video vbox unfortunately. Maybe for the last round...

A nice chilled out day tomorrow with just loading the car onto the trailer to do.

After a month and a half of work on it and all the various setbacks it is really good to be in this position

 

I love Cadwell.

First off huge thanks to Julian for giving up his weekend to help and to do all the little jobs (and slightly bigger jobs) that need doing on race day. Always there, willing and able to get stuck in to make it right. Also to Steve for pitlane assistance through the day. Lots of other thank yous to just get there in the first place:

Mark @ Lateral for engine parts
Paul @ Zen for engine building guidance and expert geometry set up
Steve Darley for bringing down fuel for the day for me and saving a space in the paddock
Daz Davies for his help during the day

Anyway, the day itself... we arrived fashionably late but just in time for scrutineering, signing on and briefing. A quick check over and it was out for the first warm up session. Julian and Steve headed down to the pit lane (the first of many trips down there laden with tools and part of a new fitness regine with that hill !). Running on low boost and on the 50% methanol mix, the car worked great til it popped a hose off behind the bumper (bound to happen) but a quick pit lane fix and I was back out to shakedown the car.

All was working beautifully and it felt planted to the road. I came out with the fastest time in club pro despite being held up on my flying laps and was generally pleased. Although most people arent on it fully on it in warm up, it was good to give it some beans to make sure the little gremlins were ironed out. After all it had only done 350 miles on the new engine !

Back to the paddock after the session and another nut and bolt check and prep for the practice session. Mostly it is hoses and dry sump belt set up for me in this but also a quick look at datalogs to see if anything nasty was happening. All was good and ready for practice.

Practice and car was good from the off then went uber lean half way through the session - really felt like the car was holding back. Looking at the logs it was running at just over lambda 1 at full boost !! hmmmm VERY lean and not good but was only doing it intermittently. Still came out with the 2nd fastest club pro time so again was pleased but yet to really nail coppice and charlies 1 right.

Lots of head scratching, checking injectors, wiring, hoses and then a change of fuel for qualifying to Sunoco Race E85 and it was fingers crossed that it was a problem with my saturday afternoon map for methanol.

A quick bleed of the brakes and re-attach the exhaust that had come undone lol and we were good to go



Qualifying was split into 2 groups to give us more space on track - this worked well and it was possible to get a full flying lap without getting held up. A great idea but should have been done in the final too (or instead) because the traffic in that was silly.

Car felt stronger on the E85 even though still not running full boost quite yet or full ignition timing ( i had taken a couple of degrees of timing out as a safety precaution to the lean running - a token gesture I know but it set my mind at rest)

This session ended with a 1.36.5 and 3rd place. My best qualifying position this year. With still more in the car and me for the final I felt good.



What seemed like days later we were out for the final - this time instead of 10 cars out - there were 16 and although that isnt many cars compared to track days, when there is such a mixture of speeds when cars are on full speed laps and 'cool down laps' at a far slower pace than was dictated in the briefing - meeting cars at the wrong part of the track is inevitable and impossible to judge a space big enough for a full flying lap.

So the first flying lap had to be the one. It was slightly cooler now and there was oil / cement down on the track from the previous session into braking at park and into chris curve braking too so tyres werent working right from the start of the first lap so had to go for a couple of hot ones. The first was fine and second better but not quite good enough so went for a 3rd full hot lap as the tyres felt good still and I hadnt hit my target time. I dipped into the 1.36's but not as quick as I had hoped and a missed gear in the mountain section cost me. Looking at sector times though it was still a quick sector.



A couple of slower laps to recoup and back on it again ... met Mr Lloyd in the evo halfway round chris curve and had to overtake at full power around the outside mid way through - a bit butt clenching but it had killed the potential for that lap anyway so time for another and again met someone halfway through the gooseneck again ruined lap. At this point I was in 3rd place but just at the death on the last lap Martin Byford pulled ahead of me to take the podium slot by 0.1 seconds.



I didnt know til I came into the paddock and saw Julian and Steve.

Never mind - I had a ball, beat some old adversaries and came away with a car in one piece ready for the next outing this weekend at TOTB.

To qualify 3rd and to finish 4th was a great result and my best yet in club pro.

Superb day !

Thanks to everyone that popped over to say hi during the day

 

Massive congrats to Scott Robson for his club win, Paul Doyle for Club pro win in the old Zen car and to Gav in the Lateral banana for their podium.

 

Great write up Duncan.Very eventfull as usual.

So makes you feel that you was there by reading it.
