~ ~ Cal ~~ Posted September 2, 2006 Posted September 2, 2006 While you guys were in Fife I slipped up to Wallace for reasons you'll find below... Thanks go to<?xml:namespace prefix = o ns = "urn:schemas-microsoft-com:office:office" /> Russell Hulme ( Wuz) , Andy F and Russ & Craig @ Wallace performance.......all great servicio ! The background My goal has been to slowly mod my car and create a daily runner which has a reasonable combination of power mods, chassis tweaks and powerful brakes which can handle the odd track day. My suspension is untouched as yet but the brakes have been fettled and are more than adequate for track and road in their current state. So Whiteline gear to follow me finks. The aspiration is to hone my car into a reliable all-rounder B-road weapon which can extract the odd STi scalp ( if required). Of course the STi ( say a 2002 UK model for arguments sake) has many different features other than the 6 speed box, stronger brakes & better handling but I like the thought of issuing a small fright on occasion. Apparently the STi UK 2002 model had 261.5bhp at 6,000rpm and at 253 lb ft at 4000 rpm. Anyway, purpose of the post is to show how a few tweaks can dramatically transform a 215 bhp standard WRX into something a bit tastier. 3 graphs on each page represent the 3 different RR sessions I have had at Wallace ( Dastek system) over 3 different stages of tune over 12 months or so ( I kept using the same dyno set-up for consistencies sake despite having no control over weather etc !) Stage 1 - the usual attempts to let her breathe and free up some burble Factory Map + K&N panel filter, WR Sport backbox, ScoobySport decat link pipe and unsilenced centre section. Horrible standard WRX downpipe & up-pipe cat still in-situ. Stage 2 - a remap to see what gains can be realised from Doctor F Andy Forrest Map + the above ( measily 1.1 bar due to EGT / cat restrictions) Stage 3 - more serious tweaks in pursuit of more boost & ponies Revised Andy Forrest Map + ScoobySport Backbox mated to to complete turbo back TSL Thundercat system ( high flow 100 cell cat) + decat H&S up-pipe + ported turbo ( though still a standard TD04). Not hitting target boost in 2nd as I need to tweak the actuator but 3rd & 4th is hitting 1.2 bar of boost. The results (I know the real indicator is how it feels on the road but the below is a worthwhile exercise to superimpose the three runs) ( edit - the middle line should read 230 ft.lb's ) In summary, I have a nice quick spool up with torque flooding in early & strong ( above is 4th gear on all runs (I believe)) with peak torque almost delivered at only 3500 rpm. Bottom line is 280 bhp @ 5750 rpm and 265 ft.lbs @ 5200 rpm. [H] Any thoughts ..as to what should come next ( TD04 hybrid perhaps plus larger IC ?) Not really keen on going beyond 300 bhp in line with my reliability mindset. Handling recommendations also welcome - not keen on the brutal drop of Teins but Eibachs may be next. However, the standard springs are excellent on a bumpy B-road so maybe Whiteline gear alone may prove the remedy ? Cheers Cal p.s Thanks also go you loony tunes for providing the inspiration & muchos knowledge !!!!!!!!!!!!
dipsy Posted September 2, 2006 Posted September 2, 2006 Cal would you need to see Andy f again after you adjust the waste actuator and Andy f did a articles of his different hybrid turbos in scooby magazine and got good results with the tdo4 hybrid
wrxmania Posted September 2, 2006 Posted September 2, 2006 Looks well thought out and executed Cal - just what I had planned. TD04 Hybrid from Andy to perfect the maopping, with an STI topmount (just sold mine too []). Springs - fit the Prodrive ones - the Eibach's clunk apparently and the TEINS are too low for you, as you've said above. The Prodrive ones were in development for ages so must be good - they tightened up my steering, lost a lot of body roll etc, but was still very compliant on the road, not at all hard, and even Julie described the car as feeling attached to the road. Well worth the money. I had Whiteline rear drop links too. Good luck! Brian []
~ ~ Cal ~~ Posted September 2, 2006 Author Posted September 2, 2006 Cheers lads....... Dipsy - no need for remap woith the actuator tweak ( just one turn when the heat shield is next off) but yes a remap would be required with the TD04 along with a Walbro probably. Brian - my sentiments exactly. I just cannot swallow the Prodrive costs although I;ll have to bite the bullet as rattling springs would cheese me right off. I saw your car in T&C again yesterday - I thought it looked slightly lower and more taught !. For the benefit of the newbies who are considering the modding game. Do your homework on here, buy all the selected mods in a "oner" and then install promptly before hitting Andy F's doorstep sharpish. I did this over 14 months or so instead ( paretly beause you are never satisfied when modding)........I have paid more for the pleasure but in hindsight I got to appreciate each tweak as the car evolved ( whilst watching the fuel gauge reduce !) Awra' breast ( edit :- the filter wont let me type "b-reast" !) Cal
wrxmania Posted September 2, 2006 Posted September 2, 2006 I thought I saw it on the road the other day as well - must have been my imagination! Still at the same ridiculous price? And is the Prodrive splitter cracked? The Prodrive springs were less than £200 plus fitting - they cost me £330 all in - fitted, and them Prodrive geometry set-up by A F Nobles, Subaru - the Eibach's were about £160 odds I think - about £30 quid difference and not worth it if they rattle. If you're looking for a Walbro pump Russell has a nice new one in stock lol [] All the B r east. Brian []
dipsy Posted September 2, 2006 Posted September 2, 2006 Cal will you be putting your car back on the rollers after actuator tweek to see if there is any changes to your boost and torque readings ??
~ ~ Cal ~~ Posted September 2, 2006 Author Posted September 2, 2006 Cal will you be putting your car back on the rollers after actuator tweek to see if there is any changes to your boost and torque readings ?? Nah...........these runs were done in 4th anyways. Andy Forrest just recommended I do this to extract the best from the map as the car was just shy of target boost in 2nd gear during the mapping session i.e wasn't picking up as sharply as it should be in 2nd. Bairn - you're a bad influence my son ! The splitter looks a tad goosed at the passengers side but nothing major. I couldn't see the crack underneath due the close proximity of a wall but pretty sure it got twatted ( although i might be wrong) CGS
st3ph3n Posted September 2, 2006 Posted September 2, 2006 Cal the whiteline gear is a must have next. The droplinks and a proper geometery setup are easily the best mod for the car and improve the handling by so much. Your figures are interesting indeed. I just made 248/232 with 3rd cat deleted, unresonated centre and H+S Backbox. No mapping though.
STi_Bandit Posted September 2, 2006 Posted September 2, 2006 Cal those are great figures def an STi Killer I made 267bhp/268lbf.ft today thats an 04 STi with Angled back-box and unreasonated centre section. Very nice figures mate well done [][Y]
WUZ Posted September 3, 2006 Posted September 3, 2006 Good to see that the car is running just how you wanted it.....a real "sleeper" Always did like how this car ran. Russell ps - fitted a TD04/05 hybrid recently, (not one of AndyF's but another supplier) - WELL IMPRESSED is the best way to describe it!
~ ~ Cal ~~ Posted September 3, 2006 Author Posted September 3, 2006 Thanks Russell ! .............when are you back ? Did Angela get my new bambino "kerd". I think I will require your services on your return :- * Rear discs & pads - deffo * New front pads - deffo * Oil Change - unless I bite the bullet and give it a bash myself * Rear Drop links - again unless I bite the bullet and give it a bash myself * Rear ARB - if purchased in time Cheers mate - hope all is going well in pursuit of our favourite hydrocarbon Cal p.s edit :- anyone know what insurers are like w.r.t ARB kits ?
WUZ Posted September 3, 2006 Posted September 3, 2006 Yes M8 - she did get your card. Thanks! Due home in 24 days so if you can hold on then great......................if not, give itr a bash yourself. After all, what can go wrong?[^o)] Russell
Russs Posted September 3, 2006 Posted September 3, 2006 Nice numbers Did you manage to find out why it was lean?
WUZ Posted September 3, 2006 Posted September 3, 2006 Define LEAN - what AFR's are we talking here? On Boost? or Off Boost? Figures would help this discussion. Russell
andrew_forrest Posted September 3, 2006 Posted September 3, 2006 It's certainly not lean on the road. As wuz said, define lean ? Andy
ANDYJDMSTI Posted September 3, 2006 Posted September 3, 2006 For the outlay of costs over 14 months, could you not have got yourself a sorted 2002 STI (ppp) with more power??? Then atleast you could babble on about having an STI with STI scalping capabilities [] Just a thought.
~ ~ Cal ~~ Posted September 3, 2006 Author Posted September 3, 2006 In hindsight probably yes......but my burd at the time was not keen on the ironing board "tail" as she called it and I personally think the gold wheels ain't so "purdy". As you know your self, you buy something and aren't content for very long so start some tinkering. This of course propagates into a modding cancer. So STi performance became something to aim for ( or an equivalent WRX PPP). My signature is just a virtual tongue in cheek designed to wind up the purists in a banter like fashion. And I'm not babbling, I am burbling [] .......[] But ultimately you are correct, having just got married and bought a new gaff, a new scooby ain't on the cards for a while. Hence I mod away quietly in pursuit of something rapid that won't me stick out like a bonar on a daschund....Give me a new Litchfield Type 25 though and I'll give you one of my kidney's ! Cheers CGS
colin_ross Posted September 3, 2006 Posted September 3, 2006 But ultimately you are correct, having just got married and bought a new gaff, a new scooby ain't on the cards for a while. What about an old one Cal, haven't you heard? Classics rule! []
~ ~ Cal ~~ Posted September 3, 2006 Author Posted September 3, 2006 It's certainly not lean on the road. As wuz said, define lean ? Andy Andy - I have sent you a PM on this issue. I think we have a repeat situation of what happened to the Dastek folk yesterday i.e http://forums.sidc.co.uk/forums/771122/ShowPost.aspx. I think my readings went from 11.25 to 13 at higher end of the rev. range. I think it's wise of Wallace to forewarn me of this issue as there may genuinely be something wrong with my car. However, I think it was just an anomaly and I trust Andy's mappin implicitly. Cheers Cal
~ ~ Cal ~~ Posted September 3, 2006 Author Posted September 3, 2006 But ultimately you are correct, having just got married and bought a new gaff, a new scooby ain't on the cards for a while. What about an old one Cal, haven't you heard? Classics rule! [] As much as I like the old skool whips I need a daily driver that's reliable. I would cold turkey if I didn't drive her everyday anyway. I am more of a millenium man although the idea of a sneider car for winter has crossed my mind
Russs Posted September 3, 2006 Posted September 3, 2006 Andy.F wrote "It's certainly not lean on the road." Not nice, this internet conjecture, is it?! At least I didn't say "the person that mapped it should've known better". Cal, IF Dastek yesterday did have an issue with their wideband, it may have been down to the new logging software (1st time out). We are using a different wideband without the software (mapped several other cars up to 400bhp last week with no issues). If you'd like to drop in one evening this week I'll gladly verify the fueling with two different widebands. May at least give you (and Andy!) some peace of mind. I'd much prefer help out rather than argue.
craig mac Posted September 3, 2006 Posted September 3, 2006 []Hope it was none of the evo's at Japerformance today LOL (J/kin Russs)Coz none made it above 370[] Craig
Russs Posted September 3, 2006 Posted September 3, 2006 Yes, one of them at least! Dyno dynamics dyno's are very open to operator "error" shall we say!
craig mac Posted September 3, 2006 Posted September 3, 2006 Russs What do you guys charge for a power run? It would be very intersting to compare the 3, Japerformance, Dastek Dalgety and yourselves Craig
