It's taken a fair bit of work (and investment), but i've now acheived over the target power that i'd been aiming for - Check out the ambient and intake temps!



In this spec, it's made..
534hp/490ftlb @ 1.7 Bar on Sainsbury's 95RON
568hp/515ftlb @ 2.0 Bar on V-Power
617hp/555ftlb @ 2.0 Bar on Sunoco GTPlus 109 RON

There's room for a bit more power too - I haven't heard any sparkly det yet whilst pushing the tune up, and am currently running 22-25 degrees of timing at full load. I'm tempted to increase the boost a bit, higher up in the rev-range to try and flatten out the torque and increase the peak power.

The car has been modified from standard, developed and mapped by me. - My main aim was to keep it looking as standard as possible from the outside, whilst delivering the power to surprise a litre sportsbike.

It's safe to say it's an animal to drive on the road at full throttle, yet surprisingly comfortable, economical and easy to drive around town, off boost.

I'll be back on the dyno this weekend, to see if there's any more to be had out of it, and i'll update the thread in due course.

 

wow nice one mate bet your over the moon.

Why did you go for a 2.35 over 2 or 2.5. i had speced that up at rcm but they seem to think 2.5 is the way to go, interested to hear your thoughts ?

 

Awesome Bloody good spec too

 

Cracking figures!

Welcome to the 600bhp club!

 

WTF

TX.

Edit - interesting to see you using an Autronic SM4 ECU (same as mine!) - why not Solaris etc?

 

Double post.

 

Great figures Rich

Tony

 

Love the standard look.......you didn,t go for the sport bumpers and bonnet look in the end then....?

 

"Standard" look is the new bling!

 

nice on Rich
was a long hot day but i am glad i stayed to the end
that was an awesome performance
FB Tuning
glad to have you looking after my car


not sure about the rear spoiler aditions though

 

Nice one Rich. Should make a fair bit more on a January morning Dyno session

 

holy **** how much money went into that car

 

It shouldnt make any more peak power regardless of the weather. That's what the compensation factors within the dyno software are for.

 

97mm crank is a mistake, or I want one too !

Amazing results, but what's that like to drive ?

Scary ?

dunx

 

i followed Rich to the dyno
i think the next mod will need to be wheely bars

 

Superb car, It sounds as good as it goes! it is the loudest car I have ever heard good work Rich

 

Holy sweet lord mate. That is outstanding.

Glad to see all the hard work has paid off mate. Enjoy it.

Steve

 

WOW, very impressed :-)

 

thats got a punch mate. whats the mpg like off boost

 

I think thats a silly thing to do, and it looks horrible you must sell it, to Meeeeeeeeeeeee
serious power I bet thats a real hoot to drive, im on the hunt for 300bhp I cant even imagine what a 600 odd bhp car would feel like, Hate to think what Money youve put into it

Well done to you mate great looking car with fantastic power I Love it

 

very impressive, loving the standard'ness

 

Awesomke mate wouldnt like to think how much it has cost you tho, but I bet you aint thinking about that at the moment

 

Cheers Tony

2.35 is tried and tested, and was the sensible option at the time of build

"WTF" - That's what some guy on an R1 said when we stopped at a set of traffic lights

SM4 is a very capable ecu - It doesn't have all the bells and whistles of the Syvecs, but it's adequate for my needs.

 

No, it makes far too much noise to be convincingly disguised as a 2.0 Sport

Cheers Pete - I wouldn't want those two blokes sat in the boot all the time - slow me down too much

I haven't added it all up, but at a guess around £23k including buying the car, but not taking into account any of my labour.

 

Cheers mate - Hope you are well

If you can force yourself to sit at the legal limit on the motorway, then it returns around 280 miles to a 60Ltrs tank full. Although a quick calculation shows that at full boost @7k rpm it's consuming just over 3.75Ltrs of fuel per minute


....bring me your car and around £25K, and you could be driving something very similar

 

Yup, me too. Put the money where it counts.

 

is that all

 

The top of the rod would probably hit the head though

Typo corrected

 

OK, OK - maybe closer to £30k then

 

Just a shame he can't drive it as well as I can, hey hun....
