1.1bar boost?
Hi all,
I've recently bought an MY99 Impreza with the following mods; Green panel filter Walbro fuel pump Ecutek ecu and re-map Magnex ded-cat pipes Magnex downpipe Magnex full system I have a folder full of receipts for all the work carried out. The last owner said it would be running at around 270bhp. It also has a boost gauge which holds at about 1.1bar. Basically, all I want to know is, is 1.1bar 270bhp or should I be looking for more or is this too much? My next step is a P1 turbo and re-map. |
bhp
hi mate pretty new to the scooby world myself but as far as i know it should be abit more because the downpipe decat adds about 30bhp instantly, if its a import you could start with 240bhp,260bhp,280bhp all depending on what year and spec hope i was some help

1.1bar is about 17psi of pressure which is the force of air the turbo is feeding the engine;)

I thought 270bhp was about the max my turbo could go to? Anything after that would require a new one and a re-map? |
A UK Turbo basic spec is 215bhp so with the mods i would say its probably more around 250bhp possible 260bhp. I had a UK spec a while ago with almost the same mods and this was what it was running at.

why a P1 turbo?

Only reason I'm going for the VF28 is because I thought it would be cheaper than buying new. Forgot to ask too, would I see different boost pressure if iI use different fuel? I put in Tesco 99 last week and I'm pretty sure it was peaking at 1.4 and holding 1.2. But I recently put in BP ultimate and now I'm seeing a peak of 1.2, holding 1.1?? |
I have a similar set-up to yours.
Magnex centre/backbox, JR Panel filter, Ninja Sports Cat downpipe. Std turbo Td04 like yours, remapped via ecutek to 273bhp/273lbft @ 1.25bar. TD04 doesn't do much more than 270-280bhp. I was also thinking VF28, would like to see 300-320bhp/300lbft. Turbo change, fuel pump and remap should see that. |
TD04 is good for no more than 270-280bhp. Sounds like yours is running at its max. Bet you get a good early spool up though?
|
i was told the td04 can give a 300 bhp, where as a td05 can give 350bhp with suporting mods, injector/psi levels ect.
i have a uk classic, but i'm hoping to be in or very near the 300bhp mark |
Not on proper rollers!! Unless its an Andy F hybrid of course.
|
it was andy f who i asked about bhp levels i would get with the td05 turbo i have. there are a couple of other mods i have too, but hoping i'm around the 300bhp mark
sorry, for hi-jacking the thread. |
A TD05 will as you say get upto 350bhp, but a STANDARD TD04 is limited to 270-280bhp?
One of Andy Fs hybrids TD04 however can go up to 320bhp I think? When you say you asked about the TD05 you have do you mean TD04? Unless you have swapped it you should have a TD04? |
Unless you have an early UK Turbo which has the TD05 of course? Didn't think about that ;)
