Interesting comparison Martyn, something i wasnt expecting, but i will say the 2.5 defo looks laggy . Maybe its the hybrid 35/42. I was thinking you may have shown one where there was a tad more lower down, like one of the clinics here https://www.scoobynet.com/showpost.p...&postcount=317

Effectively a 3000rpm power band, that would require less stirring of the box.

 

Well I can show this one, but as it isn't on the same turbo it becomes meaningless as a comparison.

 

Overlay the 2 Martyn, there is only 20bhp in it.

 

tbh,i never started out wanting a car that had more power than everyone elses had,just so i could say look i have a graph better than yours when down the pub.before i bought this car i had 2 forged engines built by 2 different companies.the first turbo i chose was a md321t+ and on the second one i chose the standered fit gt30.now if i was wanting massive power then i would have gone rotated back then and fitted a bigger turbo.all i have ever wanted is a car that puts a smile on my face every time i got in it.but most of all was able to handle the power and handle it reliably.now as a lot may already know the first 2 engines i had built by the 2 different companies (which i dont want to mention anymore) may as well been made from chocolate and jelly babies.so i had 2 years of dissapointment and missery,but then this motor came up for sale and had just had the engine built and fully specced up by enginetuner and of course scott the previous owner.after having 2 years of failures i was a bit doubtfull of even going on with scoobs as my confidence was at rock bottom.but i took the chance and bought the car which i can honestly say was the best move i have ever made since scooby ownership.as soon as i drove the car my smile was back, and even with the power it produces i have never got in it and thought i had to baby it so it will last me.i'm not someone that will sit there and bounce it off the rev limiter or doughnut it around halfords car park on saturday night,but i do like to drive it and drive it i do,the car gets used for what it was built for and i know what the risks are in running cars at this level.i am pretty confident that if i wanted the engine to produce more power by upping the boost above the 2 bar it is running and using race fuel then no doubt it would,but i never wanted a graph saying 700bhp(even though it would be nice).when i took the car back to enginetuner to be mapped on meth i did so because i had a 210litre drum of it at home,and when i got there i asked martyn to give me a car that would produce the goods on track and not a car that was mapped to the max to produce a good graph,which i must say that by the way it drives and the the way the power is put down to the road he has done an amazing job.i will be honest and say that i always used to go on about lag and thats the main reason that my first 2 engines were 2.5l,but after owning this car for nearly 10 months now i wouldnt change it for the world.now there will be cars running more power than mine and i hope they have as much fun from them as i do from mine, because for me thats what its all about.

 

wow, my eyes hurt!

A few new lines and paragraphs wouldnt be a bad idea.

 

iamonly4yearsoldsothinkyourselfluckyiputafullstopi nhereandthere.

 

Nail on head Arf, if your happy thats all that matters, although i never questioned that.

 

well said bigarf if only I had to worry about 600+bhp

 

i know that steven,it wasnt directed at anyone inperticular.just basically wanted to say that sometimes the big power game becomes an obsession and goes beyond what its all first started out to be.FUN.
just make the most of what you have mate.

 

 

know what you mean, which is why i like my hatchback. its brilliant at what it does.

 

i remember some of your write ups bigarf so hats off to ya pal well done mate

 

Its never been an obsession with me I have always said that I just want a car that scares the **** out of me when I accelerate

Should have stayed at 350bhp, then Steve. Will pop down this week, if you're off work, you can take me for a spin in it along past the Angel.

 

Cheers for thinking about the "1" - too many big guns on there already .

 

Agree totaly. I just wanted a brutaly quick car, that had usable controlable power, was reliable and put a grin on my face. And that is what I have.

Thanks to API, Harvey, Jules, JGM and Bob Rawle
I have your old MD321T+ on my car and it pulls like a train

 

I don't think that power would quite cut it Its only 50mph road for quite a bit now around the angel and on the motorway so it doesn't take much speed to get banned around there!

 

Meh, you drive, I'll watch for coppers.

As stated, it would prove fruitless as they are using very different turbos. 1 has a stock .63 GT35R and the other a hybrid .82 GT35/42R.
Coming back to this lag thing though, compare it if you will to the likes of Mike Latimers awesome Billet equipped 35R and Simons Green beast.
Both are using the larger engines, yet neither has more power at less than 5000rpm than Arfs, or so it would seem looking at the dyno graphs alone. The only point I wanted to get across, was that dyno graphs can be misleading for judging spool.










Martyn

 

GT35/42 0.82 a/r on 2.5 with 20% meth

 

banny what was that car like to drive compared to yours? doesnt seem much revs to play with? how was it around town? straight line drag and i can imagine it to be awesome!

 

Much more responsive, eager to go in any gear and no need to drop a gear. It revved to 8k plus but on dyno during mapping it was not revved that far.

Even made Simon giggle like a child, first time he went in it

 

lol sounds awesome! i wanna see 600+ from you this year on the classic

 

just out of interest steve as you mentioned it, and i have never taken much notice at where mine makes full boost in whatever gear i thought i would see what mine did in 6th gear.i read in your build thread that you were running at just under 1.6bar peak boost.so i set my defi warning at 1.6bar and did a few runs in 6th.from what i can gather mine is hitting 1.6bar at around 4100rpm,so i think really there pretty evenly matched to say you have 200cc more and a smaller turbo housing.that was on the vpower only map btw.

 

Interesting Arf, what box you running?

Steve's currently runs 1.8 bar in the mid range tapering very quickly to 1.54 bar where it makes peak power due to fuel shortage.

 

i'm on the standered uk non dccd 6 speed mate.dont know if that will make any difference as its all getting too technical for me now.

 

LOL, know what you mean.

Depending on tyre size, the 300rpm equates to anywhere between 15 and 20mph speed difference for boost. On your box, Steve's would probably do it at around 3400.

 

Has Steves been on a rolling road recently as I would be interested in what the curve for it looks like ?

 

The other week Martyn. New build, did about 30 miles bedding in, and then started to push a bit after an oil change. Was done on Zen's dyno with Paul mapping. We didnt print a graph off, as its no where near completed due to the injectors being maxed out.

Will see if i can get Paul to upload a graph.
