Took above car to power station yesterday for a power run following andy f remap on tuesday, did'nt knowthat their known for conservative figures, apparently MLR & RSOC wont use them for that reson, anyway well happy she did 364.7bhp & 481.3nm (thats about 355flbs), chuffed, cheers andy.

 

What sort of mods does it have to get to that power?

 

Those are impressive figures for a wrx - let us know what you had done

I was thinking of getting some mods done to my 2005 WRX PPP

I thought anything above 330/330 ish wasn't safe/reliable ?

 

Norman.

Click view my Scooby - it's the normal stuff

TX.

 

So if I just say to the garage 'give me the usual' I too could be driving a 365 bhp monster !

 

It got to 329.1 & 476.5nm(350ish flbs), with 3" revolution system & sport cat, zero sports induction & pipework, walbro 255lph pump, iridium plugs,td05-20g turbo, andy forrest remap, after the map fitted an sti v8 intercooler, and then had a power run at power station, Then replaced the sport cat for a de-cat, magnex up pipe, and another andy f map, back to power station and 364.7 & 481.3 nm (355flbs ish), not bad for a humble wrx, thinking about bigger injectors now.

 

Mighty impressive there mate, bet your chuffed

 

How come you aint got a good dump valve as that would give you that extra 36 bhp to reach 400 bhp, can`t believe you forgot to get a good one fitted.

 

Nice, whats the WHP ?

 

Got a forge vta dv so it would have only made 329 without it,

 

242.0bhp but thats power station for you.

 

^^ That's close to my Spec C in standard guise. 242bhp should be about 295bhp at the fly though Certainly was the case when I went on a RR a few months back.

TX.

Edit - no offence intended fella.

 

Try power stations rollers, as explained to me by Mr Cookson their rr operator they had a spec c rolling roaded at power engineering's rr got a figure drove it back to power station put it on the rollers (same tank of fuel) over 15BHP less, Andy forrest told me power station are up to 50% higher losses between fly wheel and wheels than some other rr's i,e. 120bhp loss would only be 60bhp loss, so could have made circa 300bhp@wheels,could have taken it somewhere else and got a hugely exagerated figure but i allways use power station to see true progress, who do you use?

 

Nice one Not far from that target of 363 bhp then

Your std WRX injectors are coping with that spec/turbo at the moment, I'd be thinking about uprating the std WRX pistons before stepping up to the next stage on turbo/injectors, then you can run some serious boost


ps If you would like to see 400bhp, I can simply recommend a specific rolling road to you


cheers

Andy

 

looking at doing the same to my wrx going to chat to zen 2moz, well done mate sweet car

 

Cheers Andy, pretty much spot on with the estimates for that particular rolling road mate 364.7 & 481.3nm and you were rite about the wheel power % loss there too(242.0whp), the rolling road opperator also confirmed "concervative figures" too, i think some of the doubters should try a power run there for themselfs, P.S. pm me the rolling roads that i'll see 400bhp on.

 

What was the WHP when you had it mapped mate, 242 I think would be disappointing for the mods you listed.

 

I thought that RR's measured power at the wheels then used a %age to convert to fly power ie to calculate trans losses So any RR should get the wheel power about right, it just depends what %age they use to convert to fly bhp. Right or wrong?

My Spec C was about 242bhp at wheels which %aged up to 295bhp at fly ...

TX.

PS

I went to Surrey Rolling Road.

 

Well lane's dyno should get you over 400 with no addditional mods.........

 

Impressive figures! What did you get when Andy calculated the power for you on the road?

Not had mine on a RR but Andy said mine would likely be running 360/390 by doing some more wizardry on his laptop. I'm running an STI with a decat and uprated fuel pump... heavily modded lol

If you are still reading this post, cheer Andy. The car is so much more responsive and better to drive.

 

Wrong I'm afraid. Rolling roads differ in design to the extent that none of the different makes will agree on a wheel hp figure. The DD you ran on tends to give the highest wheel figures (thats one reason MLR quote WHP ) The MAHA rollers show higher losses but comparing the two via flywheel figures, they are usually within 5% of each other.

If tested on a DD or Dastek rolling road, this car would show over 300 WHP.

Thanks Mikkel I normally only run the power prediction when mapping at home on my purpose built track its difficult finding a proper level stretch when I'm mapping away, Wales in this case.

cheers

Andy

 

Thanks andy for sorting that out, was starting to feel abit harassed by mr.c & mr.d allmost asiff they where calling me a bull****er, anyway top job once again.

 

Asking for clarification against a high BHP claim is hardly calling you a bullsh1tter mate. Road mapped WHP is the most honest claim to the power you are running, hence why people are interested to see what AF road mapped it to.

 

Retard!

 

Here is an example of the other end of the rolling road transmission loss level.



Does this do more to impress the WHP crew ? shouldn't it have 400 at the flywheel ?

 

you know the figures, the rolling road and andy's explaination, you know as much as me, im no expert but im very happy with its performance

 

I know you made 242WHP on the RR, the question was "What was the WHP when you had it mapped ?" I thought AF did road mapping and would therefore have the power at the wheels whilst mapping.

Don't take offence people like me are genuinely interested in what mods you have done and what the real world power benefits have been. To congratulate you on a RR figure would be patronising in the least without knowing the road WHP. I found it interesting for example that your BHP was higher than the torque figure, generally the 2.5's I have seen mapped are higher in torque. (not a criticism, just an interested observation).

If I thought you were bullsh1tting I would tell you rather than take an interest in the modifications you have done. The fact that you have a modified 2.5 is of more interest to me than some figure from a generous or indeed conservative RR

Andy I think you are getting the wrong end of the stick, what I was after was road mapping data not more RR fiction.

 

I hope that you don't mean me! I'm just a simpleton really as I don't understand it at all & your explanation above hasn't helped, sorry

My standard car was RR'd at SRR as stated above when it got circa 242bhp at wheels & 295bhp at the fly. I then got a few bits & pieces done followed by a remap by Bob R where Bob quoted power as close to 300bhp at wheels & about 375bhp at the fly. Still doesn't mean a lot to me although I do know that the car is now fecking fast!

TX.

 

I'm a simpleyton too, i was just pleased with the figures cos it came out of the box with 227bhp @ fly and now its scary quick, dont know much about rr's only the one i used gives conservative figures, as for whp & transmition losses .

 

Forget about numbers just enjoy the car it sounds nicely moddified. It would just be interesting to know what it made on the Road rather than the Rollers thats all
