In a nut shell rob. As they are the out put is extremely healthy for a auto car. If I wanted more out right power I could of pushed mark to put on a smaller pulley. Though he said I'm making healthy boost as it is and don't need it. Though you can imagine the outcome if I did. Right now I'm very happy with the car, with lower psi tires and my new dampers I grip much better and go around corners like a purse snatcher hehe. Here's the best way to look at my new found wheel power. All auto car. Supercharging a stock auto car with only a filter keeping all cats in will see u at 210whp. Adding a de cat manifold and a HFC 200 cell front pipe with full premium exhaust will see you to 222whp. Adding a water meth system will see you 16-17 whp. All numbers off dynos but another cars figures will vary. All are done in stages and a must to get the best gains. Just put this up to get a idea and concept for people to see the stages of how we get extra power. After all that's why we have this forum, to share info. With this I can see how a water meth kit is a viable option to gains and bang for buck. £200-300 for the kit of the shelf and fit it yourself. Needs mapping then a few quid on top of when you fill up with fuel. Don't forget you can run 100% water with gains but of course less. Water is free.. ; ) I know some one who is going to fit a kit to his eight six and run just water 1st. I'm intrigued at the data. Can't wait.

Thanks Lauren, but personally its a decent gain as you certainly feel it behind the wheel. There is so much more scope here. Anyway the power gains is only a bonus, and looking at that alone is missing the point. its about consistent efficient power all All I need to do is pay an extra fiver to my full tank of fuel thats it.thanks for the advice on my final drive by the way will look into that one for the future.

Thanks rob. Wait till you see the iat data. Best part is look at my new torque curve, well up from no water meth. Pulls hard in any gear. Its not just the kit its how mark at abbey tuned it! All the kit does is open new doors for professional tuners to extract safer performance.

After with water meth. In my opinion I'm making power more torque whilst being more efficient, safer and having much lower peak iat (intake air temps) by 15 degrees. So in short I can run more timing which equals more boost then equals more wheel power. So in writing I've upped wheel horse power by 16whp and torque by 11lbs ft on the wheel. So that's about or over 25-28bhp fly wheel. Please wait to iat data that's the big one! More power than most manuals on a 75mm pulley and maybe the most powerful sprintex auto.

So as you all know I have had a devils own kit fitted. We had had a awesome debate. So it is data that was needed and I will post it below. There is a before and after water methanol injection dyno runs. Point to note I'm running a stock 75mm pulley and the other point to note is I'm an auto and results are always 10whp or so less than manual cars.Mark himself will post iat data to follow. For him to post data says it all really in my mind. Also since I'm the first fa20 in u.k to have this set up and mark and I are very pleased thus far. Obviously I left abbey with a massive smile as that's the normal effect they have on me over there. Before. S.c no water meth.

With a s.c or turbo you would of crackerd that z4

Your very low. I'd hate that on my car. You get about town ok?

Why did you not buy a auto eight- six? Fun don't have to stop and looks better than a hot hatch!

What year and model z4. If it was a 335is then that gap would of been more. So you did drop it in the corners?

Que paso hermano.Me llamo James,Yo debo España pero nacido aquí.He elegido la HKS legamax premium tubo de escape.. Confía en mí. Su increíble Búscalo encima del tubo. Su mi elección personal sólo así como todo lo posible para hacerles caso todo depende de ti tubo como tu en España hermano. There's not much performance difference in pipes, its all sound really. The difference is in de catting. More air flow.you sound so Spanish, loud and has to look good hehe. Yo soy exactamente lo mismo. If you have no emissions test in Spain de cat your manifold and front pipe if you really want loud! ; ) then get a Japanese pipe as they are normally the best quality. Adios bro happy pipe hunting!

What error code did you get off the obd port mate?

Your in Poole. Not far from me then. Let me know if you want to go for meet! We all know metallic silver is the daddy lol

I agree with rob very expensive! They do look good but for that price I'd go with any rays, oz hlt's or Enkei racing line! Probably with decent rubber too! Those trds are only 7.5 wide too. I mean look at me already looking for wider rubber after getting my blower. The above should be lighter and stronger i suspect too.

Don't ask and I won't tell you lies! Haha

Just don't ask how he got the money. Lol dude I don't remember a Morrison's Lol see you tomorrow!

For me its hard to see how the cobra system has the label of being so loud. Not heard one in person. I got a cobra non res front pipe with a 200cell cat but with a de cat manifold and even now I think I'm not that loud. Maybe its the rest of the cobra system. We should get the dB tester out at abbey tomorrow since I'm planning some track time to. Keith I hope your there want to hear your pipes dude. I like loud ; ) I cant say if there is much of a difference in dB from a res to a non res , the resonated for me just gave me a deeper tone and after a swapped to the non res it gave me a true ricer sound top end that high pitched rev. Love it. But on the swap out I de catted my manifold so really my view might me pointless as the car got much louder. Lol

Its cool Dave. We just all have different goals and we should tailor are spending to what we want to do with our cars. I just want a fast road 8-6.. So I've spent a lot of engine, braking, noise and wheels. Those that want track cars will go electronic trickery or high end coil overs. Then again if you where very fortunate then build the best you can as money is no object. But I agree coil overs would be better and offer more adjustment but I don't really need them if I'm honest. The car does all I really need it to do just that added initial traction is all. Dampers would help that I guess with lower psi tires. But Dave you point is totally valid just came across like a slap Lol ; )

What's the biggest tire size you can fit on a 18x8? I'm running 225/40/18 yokohama v105s and they complement my abbey tuned car well. It tames the extra power but also let's the back end twitch when you go drivers aids half off. Let's say I wanted more grip in the future when i go for more speed and ultimate grip but as a result less playfulness,what's the most I can fit on a 18x8 wheel. I was told a 235/40 will fit. What else?

I'm actual happy with my performance now. Just building on my defensive driver training I've got. Basically same as the police interceptors get. I'm a mostly road driver and hardly go on track. my car has loads of mods already, mods im srill getting to grips with. I cannot justify coil overs right now after a massive list at abbey and a new house. I'm sure robs dampers will be enough for now.actually more than enough also cheap thanks rob ; ). So manning up to spend more money for something I feel I don't need just yet is pointless Dave, not to mention if you knew me I'm the last guy that needs to man up... Trust me!.all I'm saying. you guys are probably right but end of the day I'm happy and a great road driver, leave you pros to tackle tss. I'm actually booked in this sat for koni fitting and another map. I could buy set of coil overs tomorrow just feel dampers lower psi and more grip will be adequate.

Here are some pics I've found of scion frs's running on 245/35/18s on 18x8s. Could this be right? And can anyone see a drama with this fitment for fast road? Or is this just a bunch of wild yanks? Lol

Very true Lauren. Still getting used to it. Its funny how fast the car is now, you get used to the feel of it quickly but then look at your speedo and say bloody hell better ease off. You just don't realise how fast your going with f.I. Yet to try 28psi, I know Keith loves that pressure for road too ; ) What pressure are you using on road Lauren? Will 235s on a 8" give the same bite as a 235 on a 8.5" par say? Or even a 9"? Next tire choice will be stay yoko v105s, eagle f1 a2s or pilot super sports if I can get them in a 235. The big question is how would the car ride on 245s on a 18x8.. I've need told they would fit...

It seems the consensus is on 235s. I could actually fit 235s on my 18x8. I agree I love the playfulness of the slimmer rubber but I noticed the down fall on racing a new golf r the other day where I had to pull out all the stops to drop it on b roads. The down fall was coming out of very slow corners and when your about to straighten up you boot it and the car fights for a split second for grip then its perfect. That where the golf always closed in. I was surprised how the golf struggled with slowing down for fast bends and roll on corners. But once out of corners and straights it was a beast. At speed the Yoko's have surpassed all other tires I've ever used. Just the initial bite let me down. I could of gone faster with a bit more bite. So beating cars with more power is doable with your average Jo behind the wheel but like all things in life there is always some one who has your cards sorted and faster. : ) I feel slightly more initial grip is all I need. So going to wide would lose the fun factor and I just need a bit more bite than 225s has to offer and now my talent on road is now catching up slightly to my ambition. So once my Yoko's are spent I shall stick 235s on my wheels. Anyone got 235s on a 18x8 out there? Your personal view? Will 235s offer a difference to 225s on a 18x8? Jay as for the dampers they are robs old ones so getting them for a great used price! I can't warrant coil overs just yet as I feel I am now only becoming in to my own as a fast road driver and understanding how to go fast safely. So basically Ive just upgraded from novice to amateur. Once I feel I need more to match my added talent over time I shall add coil overs and more even more power etc. So dampers and slightly wider tires should do for now. I'm no rob or Lauren I would even get near to the limits of coil overs just now only managing to exploit stock shocks and eibach springs. Good thing is my talent is growing slowly so gives me time to save for more Gucci kit! Ain't out grown my jeans just yet. Waiting for rob to school me! Hint hint

I'm on eibach springs. And already on 30psi, I might drop to 28psi and see how that goes. As for a bag of cement I rather drop psi and get those dampers in. 28 psi ok to RU. Fast road on? The v105s are amazing on dry and especially wet I've not had a tire that felt like these in the wet but with the added oomph its the which static turns that give way. Let's see how they do with lower pressures and dampers.

I'm fitting adjustable dampers this weekend which should help, no coil overs as I'm mainly a fast road guy. And coik overs are more for hard track in my view. Im thinking staying 225 on my 18s but just go to pilot super sports or pilot cups as they are more dry orientated. Hard choice between the two tires. Just need to wear the Yoko's down ; )

Haha I did I almost turned round 90 degrees on a 4 way junction. : ) I'm trying to apply less throttle or feather it mid turn and awaiting the straight to floor it. But the corners is where I drop most people that try to race me. Hence the need for more rear traction. The Yoko's are awesome enough but the f.I puts a lot of pressure on them 1st and 2nd gear on tight corners. It will be good to see how everyone else with f.I copes with this. But then again I'm only on 225s.
