13% I wish..!!!

With all due respect, you obviously don't know what you're talking about..

A well designed FWD transmission would be lucky to get only 13% losses, with RWD around 18% and AWD anything from 22-24% depending on gearbox and diffs etc..!

Agree mate. Note my graph on page 1. Stipulates loss allowance of 23%

 

Thank you Jasonius and RLE

I love the fact that some members on here think they know more than the pros

 

i was told this by a reputable mapper, don't know if you fall into this category, but i'll take his word for it ta

wheel horsepower + 13% will give PPProb 320 odd, which for his mods is a good map. no way it'll produce 350. sorry. headers and other work needs doing to get to that sort of figure.

unless the formula i was given equates to a 23% transmission loss, in which case i humbly apologise

 

Alex,

Having experienced RLE's car at different stages of modification, personally i would definitely follow the 18G route, yes a bigger turbo can have slightly more lag than a standard Vf35 but with the right supporting mods (and a deep pocket ) you should be able to acheive what your after.

18 & 20g are fairly notorious for turbo surge (confirmed by a reputable mapper!) so id probably suggest finding someone closer to you who has already modified to this level & be a cheeky git & ask for a ride to see for yourself, bare in mind tho that with more power you brakes will be under more stopping stress so you may have to splash out on bigger brakes!

RLE's car pulls like a train, i've been in some bloody fast cars over the last few years, but you certainly know when he taps the pedal!

Again this is just my opinion, and each to their own

 

so is the vf35 only capable of around 350bhp then. what would be an ideal bolt on replacement.

 

Rob (RLE) was running vf35 with this chart

 

16, 18 or 20g

 

and where would you get that from and how much, and would that literaly just bolt on or do you have to make any adjustments and what would that give as apposed to the vf35.

 

You'll deffo need a remap, Rob's 18g came from Andy Forrest, think it was £1000 (or there abouts)

 

jesus that much think il keep the bloody vf35, get to about 330-340 and call it a day £1000 will by much needed suspension to cure my understeer!!!!

 

remember you can always sell your VF35.... get back £300 odd.!!

or keep your eye open in the for sale section... they do appear every now and then.!

 

PS Rob also has AST's

as mentioned above, you could always sell the Vf35 & keep your eye on the For Sale forum

 

right ok. the origanal plan was to get my 04 sti ppp up to about 330ish 340 would be better and sort the suspension for about £2ooo so is this realistic then or am i going to have to sell the house, missus, kids, and the dogs...

 

you will be pushing to do it all for 2k, won't take too much more though.

Be prepared to take a hit on parts then sell the old ones on.

was good enough to see my 03 sti type uk non PPP to 358/359

 

what was the bill?

 

Andy F. does do px on turbo's so could be less than that £1000. Go see his web site. He maps well too! ;-))

TD05-18G - goes very well and little / no extra lag. I got TD05-20G and again little extra lag, 1 bar boost by 3200 rpm, 1.65 bar by 3600 rpm. Waste gate area is ported to reduce compressor surge.

Harvey does ported and wrapped original headers, worth some spool and bhp/torque, good deal if avoiding cost of tubular steel ones, and keep the scooby rumble!

 

£2500 followed by a thick ear from the missus and the the dreaded cold shoulder . Full track day at oulton park reminded me it was more than worth it . Still gettin the cold shoulder now but who cares

 

what sort of boost are you lot running to make that much torque?? mine was mapped at powerstation, hits 1.3bar and tails off to 1.25 up top and made 334bhp and under 290lbft

ported headers
3 port solinoid
prodrive d.pipe
full 2.75" milltek
k&n panel

 

mine peaks at 1.4 bar

 

where are bob rawle and andy f based to bacause im in devon. aaarrrrrgghh

 

You are ever so slightly closer to Bob then

He is in Swindon.

Andy

 

ok ta so if i was to go to him then and say sort out the bhp and i want change to do the suspension he would be able to do it.

 

Andy is ooop north ... north of the border in Edinburgh ... but have laptop will travel!

 

what about the rolling road?

 

If you map with Bob he will e-mail you your power output and power graph. I would imagine he gets the data from the mapping session

 

the mapping yes, not the suspension

 

Isn't there an Ecutek dealer located somewhere in Devon.....?

 

there is , its in plympton but i have heard no feedback from there and when you throw the best part of £1000 you want to know that its good.
