Very impressive I hope she puts it down ok in mixed / wet I will always remember Damon hill in turkey pole position as everyone else couldn't put it on the tarmac. Bill had a smile on his face I know he's not keen on the camera's. Good luck Nick for 24
Alright, so here’s a big question, and I hope you’ll make a video about it altogether-you e had a G25-550, G25-660, and G30-770 on a 2L setup-based on your experience now, would you have done the 770 to start? I have a 2L on a G25-550 and I see 1.2 bar (on gate spring currently) by 3700, still tuning it in though. The 770 seems to match it spool wise and just adds power everywhere.
Hey man, that's a GREAT question! Perhaps one to do a video on shortly. We went 660 first, then down to a 550 as we were racing in a power:weight forumla which didn't allow over 355bhp, so the 550 was the right choice at the time. If I had my time again I would jump straight to the 770 though, it's bloody wonderful!
Also, well done on the weight loss chap, you look like a lot more streamlined 😂 With family life, work and everything else in-between, not to mention updating rhe race car, thats no mean feat 👏
Been following since you decided to build the car years ago. (vegeta gti on vortex), refresh us with the full engine details/setup? Brilliant outcome, the .61ar 770 is waiting for my next phase in the mk1.
Am i understanding correctly that the bigger turbo is spooling faster? With a mimic build to yours would you recommend the g30-770 over the g25-660? Im also considering afew couple of BW options, namely the s252sx-e and s257sx-e. 1.8t stroker to 2.0, AMB head with mild cam and aiming for a quick street car. How does this car feel in the low rpm off boost if you wouldnt mind
Hi Nick, I have a question. You have a quick car, really grippy, have you thought about dry sump system, or you think that that grip level or the type of tracks you are runing is not really neccessary?
Hey! Dry sump is something I've considered, but we currently log everything in every session and don't suffer from excess oil surge at all. Running on belts etc it's potentially another thing to go wrong that I'd rather avoid unless we're forced to!
More than 2x the power I have, I think I'll have to keep an eye on my mirrors for when Im lapped (yet again!). I'll have to accelerate my engine swap plans.
@@TeamPrawnRacing awesome! I'm looking to build a UK based 1.8T with a G30-770 too hence asking haha! Thanks for the quick reply and congrats on the car, the progression has been insane over the years!!
Get 523whp from a 3071 gen2 at 2bar on a true 1800cc JE pistoned setup. Which likes to rev higher than a stroker and doesn’t run as hot. Not much of a gain in that respect. Wonder how much % of losses have been estimated in order to get the flywheel figure. Whp is all that matters, onset and ftlb. I dont find it that impressive logically not too far in front of the aforementioned setup.
I get where you're coming from, but the reality here measured on the same dyno on the same car is quite different. A 3071 here might do somewhere around 480whp, and come on boost a solid 3-400rpm later than this does. I've had a 3076 HTA before and it was SOOOOO laggy compared to this, and still made 100bhp less power. I used to be of the same opinion that short stroke was better suited, but since going stroker I'd never go back. The difference is just night and day how it drives, and it still very happily revs out to 8500.
@@TeamPrawnRacingIs this 770 on a .83 housing? Also would reckon the characteristics of what its done on the stroker would be of similar value on a 82mm je pistoned 1.8? I’m willing to try the 770 over the 660. Going by what your showing and the outcome over last years setup which was a 660 you are comparing it too im guessing.
so at 2 bar you have 567 whp which is close to 610-620 crank max What fuel you use? One more video that proves a G30 770 is a bad performer. Garrett claims 770 crank hp which is a joke for that turbo which has a compressor map with max 69 lb/min and it chokes hard after 1.9 bar
Sorry man, but you've got it all wrong. Forget the 770 number in it's name, it's a fantastic turbo. Your estimates for crank power only allow for 8-9% trans losses, which just isn't realistic. These are measured on coastdown, and repeatable, it's 640bhp. Find me another turbo that'll make 640bhp, hold 2.2 bar at 8500rpm, and also produce 480lbft at just 3800rpm?
@@TeamPrawnRacing The 770 its not just his name ,its the Hp rating garret claims for that turbo Also dont push 2.2 bar on that one ,its overspin and you will break it As for the loses you add 80 hp loses ? Lets say your car stock has 200 crank which is close to 170 whp ,it has 30 hp loses which is 15% ,but if you tune the same car ,with the same gearbox the loses now are 80 with the 15% ,it dosnt work like that..the same loses as you have stock will be the same or little more when you tune it As for a turbo that can run that torque and power i will say a Borgwarner Efr 7670

Thanks man! Means a lot from someone who's been here a long time 😊 it's a constant juggling act!
Absolutely great figures! Cant wait to see how you get on this year bud!
Wow very impressive! See you in 2 weeks
Looking forward to this year, well done badger 5 as always
Fantastic results Nick 👍 On track it's going to be like a missile. Wish you all the best mate for the new season 🏆
Brilliant result!
Can’t wait for this season that’s a bloody rocket ship 👍🏻

what the hell did you do to shift the power curve so much to the left? nice
I guessed 545 at the crank, really damn impressed with those numbers, what octane is this on?
Car sounds absolutely fantastic by the way
great result!👌 my guess was 650 so not too far out👍
Omg that some power fully machine you got there. Let’s hope the wheel hubs handle it🤞🤞🤞.
More than 2x the power I have, I think I'll have to keep an eye on my mirrors for when Im lapped (yet again!). I'll have to accelerate my engine swap plans.
Hi bud what fuel do you use
That’s wild 😮
Wild!
Awesome❤
Badger 5 tastic
I've just looked back
I said 635😮
Great 👍 results 👏
I think the hybrid ko3 is going in the bin
Gt25 ??? In coming
653hp Let's go!
4:34 how fcking close ❤
what A/R you using?
0.61 🐌👍🏻
How it is possible to have bigger turbo and early boost? This is amazing Nick❤🏁💪
It's a good question. Was it the engine rebuild and cams?
Turbo is the same as last year :) A few changes to combustion chamber and exhaust valve seats, and a fresh build :)
I've had a look through the comments but can't see an answer!
Is this on 99 or E85?
Hey 👋🏻 this is on shell 99. We don't get E85 in the UK Sadly 😭

640 0:34
Honestly haven't got the foggiest: 628bhp
Gud vid
im guessing 400hp
1:08 (576bhp) 👀
3:43 so close 😅😂 impressive numbers sounds quality !
4:55 (641bhp) it gets better ! 😂👍
👀
627 🤞
643hp 583tq
646bhp
Did I win a hat? 🤞
431 bhp
544hp
680
637 hp

My golf was in the back ground when u went to badgers
673bhp
Can I guess 😂😂😂

Also dont push 2.2 bar on that one ,its overspin and you will break it
As for the loses you add 80 hp loses ? Lets say your car stock has 200 crank which is close to 170 whp ,it has 30 hp loses which is 15% ,but if you tune the same car ,with the same gearbox the loses now are 80 with the 15% ,it dosnt work like that..the same loses as you have stock will be the same or little more when you tune it
As for a turbo that can run that torque and power i will say a Borgwarner Efr 7670
