Megane RenaultSport 2.0 DCI175 **Back Boostin**

[Niall]

Its not easy tbh I need to redo a few bits as didnt have a geat gun so had to use hairdryer but better with heat gun so can really stretch it

Careful over heating it mate otherwise it seems to just let go and stretch a lot suddenly.

I know what u mean pal, I found that out when I did the 306 interior first time round tbh this wrap was too thick its exterior wrap and is harder to manouver so not ideal for out handle shape but will but some better stuff and redo didnt really take that long tbh

Airbox chop done

Garrett GTA1549LV

Needs a bigger turb

[Ruan]

Interesting, didn't know they ran a 1549VL...

Watercooled cartridge!

Get a GTB2056VLK on

[devils_fuel]

Sorry for not being with the kids, an airbox chop? Is that just shortening the airbox length due to it being way to big when std?

Progressing well mate

[CJ_Derv]

Il look into that ruan will that just be a straight swap you think? Would have to get another map done obv but not too clued up on GTA's

Air box mod is basically cutting a square out of the original air feed in corner of box makes a huge difference very noisy not sure if too noisy yet havent decided

[Piggy]

amazing what modern designed heads/pistons and injection systems can do with a gt1549!!

Not slating! But that clatter at idle ιs obscene! Quietness down a hell of a lot when reved though! What torque ιs ιt pushing?

It should be around the 350 360 mark pal

[Jonny b]

Cool!! Do you know what the limit ιs for these engines? You gonna push for more?

[Ed Doe]

The standard air inlet pipe is very restrictive, hence people cut the corner out of the box removing the inlet restriction generally frees up a few ponies too!

[devils_fuel]

Thanks CJ and Ed, I understand the mod now.

CJ..any better for it?

[CJ_Derv]

Il find out I guess no one had gone past 212bhp and 350ft lbs as far as I know

Initially yess improved pickup and feels bit more torquey and loud but then have the issue of throttle sensor more often now so cant get full throttle and its pissin me right off changed fuel filter too and got to clean egr and see if that makes a difference  but must be throttle sensor

PITA, rip it all out and XUD it

[Ed Doe]

CJ I think there is an issue with some of the sensors working loose on the inlet mani, which may be the cause of your problems... Might be worth looking into x

[CJ_Derv]

Could make sense as it doesnt seem to be boosting all the time gona plug it in tomorrow and have a look around pal thanks for help buddy

Can tell when its boosting and not with exhaust tone since dpf removal although launch on insta shows boost

[CJ_Derv]

Had a reset on ecu and seems ti be back boosting but not too sure if back to scratch somwthings still holding back think its got to be egr as everything cleared and still lagging

[WiNgNuTz]

You seem to be making pretty good progress with this mate, like what you're doing! Still not my cup of tea though, but if you like it, thats what counts. I also echo Darrens comment, at least its a derv!

One other thing, Liam also picked up on it, you need a new sig. So i made you one while i was bored.



Hope you likey! I won't be offended if you'd rather make your own, and dont use mine. Honest.

[Ruan]

Yeah, you'd need another map done, but in their stock application they make ~220hp - the GTBs are such incredible turbos for their size...

Should be able to see ~280-290hp at a guess, maybe even more - and they spool up stupendously quick!!

Probably the sweetest turbo for a ~2.0 engine if you want outstanding driveability.

Yeah gettin there with it pal seem to have ironed out the problem of turbo not boosting its back boosting but we believe the egr to be causing the lag so before dyno it will be gettin stripped down and cleaned

Thsts wicked matey il use that when im next on laptop nice one not got photoshop back on lappy yet cheer fella

[Ed Doe]

Can you not get the get sacked off and mapped out?

I thought I mite need a map going to speak to RS Tuning in leeds and weigh up a decent size GTB and then look at getting the injectors refurbed or uprated but the M9R are renound for injdctors siezing in head and a costly removal fee

But weighing it up need to look at bigger FMIC, bigger Blower and speak to rs about what else as id love to hit the 300hp mark if possible show the perv boys what torque is all about

Will be costly but im prepared to go for it lol

[WiNgNuTz]

No worries mate, glad you like it.

Might as well just sack the EGR off while you're there surely?

[CJ_Derv]

boost

[devils_fuel]

Oh the fun begins CJ ! XUD it and it will be all mechanical lol

[CJ_Derv]
