Hi all,

Having my car remapped for the first time soon by BRD

I'm just wondering what to expect in terms of improvements/changes to the way the car drives and its general characteristics. So I'm after experiences from people that have had their cars undergo similar transformations.

In a nutshell, I'll be going from a std MY99 with a H&S sports cat DP, decat centre and backbox.

Before the remap, I'm, having fitted a fuel pump, 3 port boost solenoid, ported headers and a VF34 turbo. Then over to Bob.

Anyone done something similar to their classic and care to share their experiences....I'm trying to wet my appetite!!

Regards,

LOL Care to elaborate?

You'll probably be jumping from 250BHP to around 310BHP with a bucket full more torque, so you should notice a fair difference.

Bob will probably set the VF34 to run 1.3-1.4bar depending on your injectors ability. But you weak link/limitation now will be the injectors and the standard TMIC.

It will also probably be smoother then standard, due to Bob's expertise.

I run a VF28 at 1.3bar in a MY00 UK an it pushed out 310 - 320BHP depending on atmospheric's.
A good friend had Bob map his MY00 Wagon with a VF34 and we are running very similar power/spec.

You won't regret it...

Thanks for that Scott- I very much doubt I'll be taking it any further as far as the engine mods goes (famous last words I know) 300bhp and similar torque should be plenty fast enough in the real world.

It's actually improvements in the car's responsiveness and the shove when the turbo comes on song -together with a wider power band- that I was after rather than headline figures per se. I also wanted to keep things nice and safe.

fuel economy will probably improve as well

get bigger injectors , 550cc

i have a vf34 , full 3" revolution decat , headers , K+N57i , fmic , 550cc injectors
mapped by Bob
mine makes 349/348 - - - my00 uk turbo

Hi mate. Nice figures!

It was my understanding that the 440s were ok to about 340bhp. I'm only thinking of around the 300bhp mark and will tell Bob not to tune it to the max, I want to give my gearbox a chance!!!!

How did you find the transition from the TD04 to the VF34. Was a significant increase in the spool threshold, a much biger midrange hit, was it better all round?

I've got this dilemma with my BR mapped 05 WRX. The response from the TD04 is fantastic (can really catch out some bigger bhp cars..!) however, I've got a VF35 waiting to go on and I'm concerned about loosing too much of that instant response.

Is the extra 40-50 bhp/ftlb going to be offset by the slower response (I'm talking real world terms). Andy F's last installment of 'Project WRX' highlighted this very point with the TD04h v's TD05 16g.

Decisions, decisions..???!!!

Send Bob an e-mail about the injectors, he will soon set you straight

I have to say the extra lag would be my main concern, I love the response from the td04 but it runs out of puff quite early.

I've been looking at AndyF's site and I think the td04 hybrid will be exactly
what I want, quick spool with a much larger power band.

I've run the spec (including current injector size) past Bob mate, he seems perfectly happy given my power aspirations. If I was going much above 300bhp I would upgrade as I personally don't think its a good idea to run any component at 100% when you have the option of being more conservative.

I defer completely to Bob's advice though. If he says I should get bigger injectors, I would!

forget the gear box, the way Bob maps my car is he brings the power in smothley rather than all at once which I am sure is why the box is still in one peice ( I can only compare this to how another garage once mapped it)

I am sure you can wreck the box just as easy at 300ft lbs than you could 320

if Bob dosn't think you need injectors then I would listern to him


One thing I will say which I may get shot down for is

when i went from a td04 to a vf34 (ish vf35/p18) after the mapping session I was chuffed, well happy with how the car preformed. On the drive home going nice and slow on the motorway tried to over take a slower car and it hit me - LAG

you will notice extra lag, don't get me wrong you soon get used to it and drive according but after driving a td04 anything will seem laggy - I was not prepared for this as everyone seemed to sugest to me a vf34 had no lag , it bothered me that much I now have a huge garret blower

you may not notice this as your car curently has not been mapped, I went from a mapped td04 to mapped vf34

and you will enjoy and will be worth the wait , Bob is a master not only at mapping but as a business man , the whole service is a pleasure unlike someothers I have read about

and all you guys who are worried about response - I was just the same 18 months ago while i stumped for a vf34, Ninnybobs and Midlife went for td05 18g
I wish I had saved my self a shed load of money and went for the bigger turbo

Thanks for your comments mate! I hear ya, but I think I'll need to stop at 300bhp, beeyond that it starts to get expensive!!! I'm prepared for a bit of extra lag, the TD04 does spool quickly, but lacks the drama of a bigger turbo I find, and -as we all know- has to wind the action down higher up the rev range, which detracts from the fun I like car to feel conspicuously tur
bocharged. I don't want some laggy beat, but a bit of a delay then Whooooooaaaaa is good fun and impresses people no end


How have others found the VF34 compared to the TDo4?

TBH I don't think the lag will be that bad, afterall, the turbo isn't that big.
If Bob has said not to worry about injectors, then you don't need to worry either

New_scooby_04

My understanding is that (thanks to the sports cat DP and ported headers helping out) the turbo will probably spool up just below 3k and really be in its stride by 3.5k. This is kinda like the TD04 before you get the cats removed etc.. Unlike the TD04, however, the VF will then pull all the way to the redline. At least, that's what I'm informed.

How much different is the response between a VF35 to a VF34 given that they have 15g v's 18g exhaust housings respectively..?

In a way I suppose it's similar to the difference between a TD05 16g v's 18g..?

NS04, when are you seeing bob..?

vf35 is not ball bearing like vf34

vf35 can have surge issues, putting on the p18 can sort this

July 1st mate. Are you taking part in the GB too?

No, I'm a very happy existing customer, you really won't be dissapointed with Bob's work, trust me..!!!

I am, however, thinking of fitting the VF35 (which I've ported so there shouldn't be any boost creep issues) and 550's/walbro that are sitting in my garage, so another visit for a map adjustment could be on the cards..!

Not sure if you have a boost gauge, but if you have (and you may or may not know this already) practice holding it at 0.5bar and 1bar for 10sec or so ie driving on the boost gauge. Not as easy as it sounds, but will come with a few practice runs. Saves you looking a complete idiot on the day..
