Hi, just wondering what's the most power anyone's run with a decat and the standard exhaust? I'm going to be fitting a hybrid but want to keep it quite low key and wondering what power the standard exhaust can flow. Cheers.
365 on mine. I personally wouldn't bother with the Hybrid though, For the gains the outlay is not worth it. Id rather spend that cash again on several TD's
Thanks for the reply Jamie. To be honest I'm only considering this route as I've already got all the parts there from my r26, so thinking may as well fit them. Otherwise like you say the cost probably isn't really worth it.
That's good figures. I do wonder sometimes if there's any point in getting a new exhaust. I'd love a cgr but is it worth it.
I wonder this too. Wouldn't a de cat or a sports cat just be fine on there own with a standard exhaust. I maybe sounding stupid here but is there much benefit upgrading the standard exhaust?
Just the usual; Decat, Pro Alloy intercooler, 630cc injectors, cone filter and a TD04HL-20T (the hybrid). Mapped by Tuur on here, doing 382hp and 520nm.
If youse were building your cars now, would you ditch the hybrid turbo and just put a larger turbo on
With a hybrid 400 is possible so you just have to decide if that’s enough for you. It gets a lot more expenive after that since more parts are being pushed. 382 is completely driveable with some sense so i am going for a bigger turbo in the future for more power.
How much power before forged engine. A hybrid and larger turbo are similar prices. Can you not run a larger turbo with less power, will it have too much turbo lag. I think 400hp would be plenty
400 may be possibly with a hybrid, but I'm dubious but that still doesn't solve the issue of the small frame turbo. Ie it running out of puff in the top end
At 382 the HP line is still climbing, 400+ nm still present. 400 Will probably max it out but that’s ultimately what you want from a turbo right? You size it according to the desired power output.
It may be, but the torque drops off massively on the td04 and it just can't sustain it to the redline Do you have a copy of the dyno graph? Can't say maxing a turbo is something I'd want to do, especially on our stock sized turbo. All your doing then is generating heat and running it out of its efficient zone. Much rather a larger turbo blowing at 80% than pushing a turbo flat out
how would you describe driving a hybrid megane. Is it a noticeable difference when you hit the accelerator compared to a stock megane.
They are not massively quicker when on the move with a hybrid tbh, I had several laps with a few different Meganes at Spa and mine didn't pull on them enough to justify the costs tbh
I can’t say i agree. The car feels totally different with the hybrid, a different car realy. Adding 50% power does that. With the uprated intercooler there is no heat issue, we monitored the intake temparature while testing so if that worried you, you are good to go. My turbo guy sizes everything around the turbo since that’s the part that ultimately limits how much power you can make.
I was already running 330 before going hybrid so not a massive step up, if your coming from a near stock powered one then it would probably feel a lot quicker Still stand by the fact that they ain't massively quicker when on the go
Which I guess is more import if your doing a track day at spa or round the ring on hot days. I'm surprised by how you don't need to fart on so much with the car. I'm used to tinkering
I was doing 350hp and 435nm with the hybrid but without the uprated intercooler. I was also losing power after each run due to heat building up. Was probably running a bit lower in real world when pushing it. Going to 382 and 520 made a huge difference on the road. To be fair i can’t comment on track performance yet. When going with just a tune i’m not sure a cooler is needed, i would think not.
With most things you get used to it, I'm sure if I drove either of yours they would feel much quicker
@Djauweh I'm planning to get my rs250 mapped soon, I just have a decat and intake. Was planning on getting an intercooler but is it not worth it? Not planning to get a hybrid turbo or anything and maybe a couple of trips to the ring a year.
Without testing i can’t say. What i can say is with a hybrid at 350 a cooler is needed. After the first run the power is dropping due to air intake temperature being too high. I noticed this on the street as well. You can always try without and add it later if needed.
Cooler is needed without hybrid ime. My inlet Temps were stupid when running a file for decat, even on the road they were pretty high, now they barely go above ambiant
Rs tuning is the closest for me. Is it best to get tuned on the dyno rather than data logging and them sending you the file,
I spoke to Andy at Engine Dynamics recently and he recommended the intercooler. Again, not for the power gain, but for IAT control. He said intercooler and remap is as far as he would recommend going too. Beyond that he said it isn't really worth it.
I spoke to Andy a few months ago about the same thing and he said the same from what I remember. But I was just after other people's views on the topic.
To be fair, the majority of the Yellow Meganes from the Megane train that lap the Ring are running stock power
I only went hybrid because i could realy. I like working on projects like these with absolutely no use to them. The car is only driven on the street for a few thousand kilomters per year and maybe 1 or 2 trackdays. It's just a hobby which gets out of hand rather quick. Looking for more power already.
Do you know if xthilox and hinterherfahrer bahram were running hybrid, on hinters YouTube it says 360
Wow that's some money. They both look like really good drivers which makes a big difference. I wouldn't mind getting some driver tuition. I think that's more important to start with
