Thats kind of what we are saying though, i dont think the headers should make that much difference at all, certainly not nearly 1000rpm, 2-300 maybe.

Im sure bob will sort it out and the car will fly

ditto i had an after market manifold ( all be it 421 design )

get the car to scobyclinic for a rolling road they may see something obvious like a leaking upipe etc

if nothing else a comparison for if \ when you move on to a bigger turbo


get out on a big dual track with a passenger 2k revs in 4th and put the accelerator to the floor watching your revs. get your passenger to give you a shout at 1 bar boost and tell us where in the rev range its hitting

for refrence my much bigger turbo is hitting 1 bar by 3k8 revs

Thanks again guys, i will scare the missus into watching the gauge for me! LOL. It's worth a laugh if nothing else! She ain't one for the speed you see, my missus.
Mind you, at 2k revs and 4th gear, when i put my foot down my car will go nowhere! Hahaha.

It's puzzling mate; must be the headers and their interaction with the turbo I guess. I have the ported headers and VF35 and although it definately comes on song later than the TD04 (it's stronger off boost though, which compensates) although its only a few hundred RPM later.

I hope you get it sorted to your satisfaction.

mad, iirc when you first had your car mapped you were not happy with the 'lag', but am I also correct in thinking that it was only mapped to 1.2 bar..?

This probably won't effect response, but as a guide Bob mapped my 05 wrx (VF35) to peak at 1.4bar (although my blitz gauge over reads at 1.5bar ) holding 1.3bar at >6000rpm.

Another thing is, just how good is ceramic coating at retaining heat (and ultimately gas flow velocity) compared to proper wrapping..?

I can't help but wonder if your car has been mapped too conservatively..!?

I really think your scoob is capable of much better performance as your choice of mods is a well proven setup for newage WRX's.

Speak to bob if you haven't already, he's always willing to give advice freely..

MaDaSS

Yeah i think i will do just that!
A quick test last night, as per the above suggestion, 2000 revs in 4th, then foot flat to floor, 1 bar boost came at i would say 3400 revs.
So this maybe normal tbh?
I appreciate all your comments though ppl, the help is welcome

Hi Mate,

That does sound a little late to me - although two important provisos

1) I'm going frm memory of my mapping session as I don't yet have a boost guage

2) I have a VF35 which spools a little earlier I think.

But I think mine was hitting 1 bar at about 2800 revs

Subjectively, if you do the foot to the floor in 4th from 2k rpm you get the impression that the turbo is starting to do its stuff from about 2700-800 then and by 3400 (the point where you get 1 bar) is really blowing!!

If you look at my delta dyno graph it seems to add up. I have as much torque at 3k rpm as the std car did at its peak of about 5k rpm

Do you have a delta dyno graph from your mapping session?

No delta dyno. Richard does not use it. He had his reasons and he told me about them, but I won't put that here as it is his business really and he cannot reply here obviously, so I don't wish to quote him.
Tried again the other morning on my way home from my lovely night shift, and it appeared this time to hit 1 bar before 3400, but still not at say 3000. So it may be ok, may be not, lol, but I cannot look at all the info.
The mate will have to do it for me!
Will post back with the "proper" test results later
I ain't doing bad, I have been going for a RR run since i had the work done, and that was miles and miles ago now.

i think the truth of the matter is you are not happy and you havn't been since the remap

i have been there before and Bob did sort it out 100% but for all so different reasons

i'm worried that even if Bob did map the car that you would still be unhappy. what you really need is a test run in another car of simular mods

if the car went on the rollers and pulled 350bhp would your opinion change ?


i say this as my dad ( a guy who has owned a gsxr 1000 up untill recently ) does not like the power delivery of my car at all, he admits it is grossly powerfull but can not deal with the lag \ power delivery ( he has hit the limmeter twice now in 3rd )

if your are ever around the worcester area you are more than welcome to a passenger seat in mine or what might be even more satisfying is if you get your wife to drive your car, some times you do not realise what you have and how stupid the speeds are

althought i stand by Bob 100% and I will stand infront of an snet fan and say he is the sole reason my car is still on the std engine, i wouldn't want you to go away thinking Bob will make you car feel 100bhp faster, as i am sure Richard has gained his rep like any other mapper


if you are going for a rr run treat your self and get down to scoobyclinic they are good guys and will give you a honest opinion unlike some rr's that will just try and sell what they have on the shelf, when my car has been on the rollers they have nothing but resepct for the other tunners who have touched the car ... this can not be said for all rr's i have visited



have you ever said to Richard you are not 100% happy ?

Good points, particularly about speaking to Richard (which I presume you have..?), however the fact that, iirc, your car is only mapped to 1.2 bar, when most make at least 1.3 no problem, will have an impact on your cars performance. I do wonder if it's been mapped a bit to conservatively..?

Initially I also missed the instant response of the mapped TD04, however within a week the VF35 started to really impress. Now I don't even notice the slightly slower response, just the constant surge from a shade over 3k to well over 6k..!

Like Rich, if you're around the Midlands sometime you're welcome to have a run in my car as a comparison (although VF35 v 34), just PM me... Performance and how it is delivered, is a very subjective thing. So a direct comparison (or as near as) would be very useful in determining if there is a problem with your car or you're just a fussy bugger expecting to much.. IMHO, I suspect the first..

It's been a few months now that you've been unhappy so I think it's time to get to the bottom of it, one way or another..

Agree with what has been said above.

1.2 bar does sound quite low, compared to what cars with your mods usually run (a peak of 1.35 seems like a comon figure). But, if a car can be made to make expected gains on 1.2. rather than 1.3 bar then surely that's a good thing? Alternatively, maybe it has been mapped conservatively; Richard may have perfectly good reasons for having done this - he is the expert. I think you really do need to have a word with him.

I came from a std TD04 map to a VF35 appropriately mapped by Bob and I honestly believe that the car is improved in all respects,even at low revs. Sure, the boost comes in a bit later, but the car is torquier low down to compensate, so its not an issue really. The real difference is how much stronger the car is when on boost and how it sustains it all the way to the red line. Remember that my car has a map that is sympathetic to the gearbox too, so I'm sure Bob could have brought the boost in more abruptly had he wished.

I'm in the SE and would be happy to take you for a spin in mine so you can compare if need be. First though, I would suggest that you have a word with Richard and see if there is anything he can do.

Bob is simply superb, as others have said, but if you go to him expecting a complete transformation this may not be possible as -although I don't have any experience of him- Richard is also reputed to be a fine mapper. Also, as previously stated it may be that tyour car isn't getting on with the headers/turbo combination as well as others might. Andy F was on a thread the other day commenting how sometimes differences in cars can make as much difference as the use of comparable turbos VF30/34/35/ TDO5 16G etc.. depending on the interaction between the cars manufacturing tolerances and the turbo chosen etc...
