How to make a 9.67 sec GT-R even Faster "The Mighty Thor" Upgrade

[peatough]

Sorry bolle?

[David]

I am guessing the idea behind the 3.8 is to keep cylinder pressures down and make power by adding more rpm to save cracking blocks from high cylinder pressure. I see no reason it won't work

Seems a waste of money rebuilding your old engine or bad advice.

You are completely right stehub, it would of been a complete waste of money IF I had rebuilt my old engine, an engine that had proven reliability and proven power - proven by the dyno run results and the UK and European quarter mile record that has been held by myself and SVM for the past 14 months.....but I didn't, under the advice of SVM I sold it complete.

My new engine does have bigger heads, bigger cams, longer rods, shorter pistons for higher revving. You may or may not know that performance parts for the R35 have changed and improved massively in the last 14 months, hence the reason for my new engine....either that or I have far too much money...thanks for your interest in my build

Stehub. Have you read the spec? Cams,big valves?

If you keep capacity the same, modify the cams go for bigger valves install cosworth pistons can you not flow more air plus run higher boost to make more power?

Read the spec before you slate fman and Amar, ur unbelievable mate.

That AMS kit looks very nice.My car is a complete animal I can't stop driving it

It will be a good year for all the SVM team

Steve, how the Devil are you? still being a keyboard Ninja?

As in your legal profession you need to gather all the facts before you put your argument forward..else your case falls apart

Heads and cams were up graded and replaced, Also Rod lengh increased and piston crown height adjusted accordingly (these items are in the short motor and required the Engine to be completely stripped

As a matter of coarse new bearings rings gaskets used as part of good engine build practice

We wanted Francis to have our "latest engine Unit, and a Deal was struck with F-man,

As the Turbo choice was more efficient in a higher RPM range we wanted the engine unit to work in partnership, this was My advice from my experiance with the family of garrett GTX Turbocharger's and from my experience with the cam and Engine block work carried out @ SVM, achieving 218 mph and more

This advice IMO was the right advice given to F=man

Hope this info is of use ,

Regards kk

Not being funny mate but your engine lasted less than 600 miles and it broke.

Car to share what you have learned ?

Fmans engine was already built so what knowledge can it learn from the hulk ?

As the hulk only done a few runs then broke , that's not what customers want .

What is the way forward ?

Let's keep this constructive and positive and not a slang match.

There is obviously issues in big power.

[Kev@SVM]

steve you are always being funny with your relented jibes at my work and company, its about time you stopped!

Unfortunately i can not share all my knowledge and experience with the GTR community , Obviously its my business and wish to keep much of my knowledge to myself to stay ahead of the game, i hope you can under stand and appreciate this as you run your own business yourself.
However i always share as much as i can, as the Hulk posts has demonstrated, info i don't mind sharing with the GTR community....

F-mans engine project has benefited from several higher spec cars SVM has created. Comp ratio,valve size,Headwork,cam profiles,Con rod lengths,piston bowl squish area's
much has been tried and tested, and development has significantly moved on by our experience building these high powered VR38 unit's for nearly 3 yrs
Not just engines, 14 plate, 16 and 19 plate clutch system's, (francis has tried Dodsun without success)we now developed our own, billet baskets and wider carbon clutches ,Fuel system's, Turbo systems, Francis is now running Hulk units !!
Progress moves on ! Hence the decission to improve F=mans car, from lets again repeat, allready the fastest qrt mile car in Europe first time out

The Hulk unit is only one of about 20 High powered units in development, infact the Hulk has 2 units of his own, one 4,2 that is almost ready to test again, and one 3.8 unit with unique features,

We pushed 3bar of boost pressure to find weak links, part of the program, block strengthening has now been improved further, and no we are not prepared to say how!
we have the great pleasure of releasing many 1000bhp+cars this year and take pride in our work ,


The Hulk project has been of great help, we now are lifting the bar 1400bhp+ we feel confident in making Reliable high power by raising our own game
may i point out, The water leak, the Hulk obtained was not Fatal, and the block has been saved ,which gave us invaluable insight into exactly the area to concentrate on
The central valley has been much strengthened amongst other crucial area's modified head gasket retention system , now again,we will put him to the 3 bar test , this time with much larger turbos ...

The high energy 3.8 units do seem to be the most robust to date, as the blocks tend t0 hold without cracking, We have had No issues with 1000bhp 3.8 units
However my Heart is still with the Hulks engine Design, I have never experienced a GTR with such urgency, I'm giving the Darton mid sleeves another try !!
We improved so much in block strengh i feel my miss hap, was unlike any other, now being in a different area, from JUN or AMS issues.. Time will tell,

Steve i hope you stop, knocking my companies efforts and get behind our passion and desire to push boundaries on this marque
If the engine Brakes, we will fix it until it doesn't when it doesn't we will push for more BHP until it does,,,development go on...how else do we get to 2000bhp?

+100, and yes for the numties on here that are frightened to leave the house and the lap top and get a life, I do swallow

Kev


Superb answer Kev but it don't matter shite as our resident stehub legal dick who doesn't want a slanging match is ignorant of what's written on here.

So stehub pls answer - what car do you actually drive? What contribution do u make on this forum apart from trying to disrupt people both personally and their own business who do make a contribution on here?

Stehub - I dont know u from Adam but its obvious you have a mission to upset Svm. Just review your posts - imaginary contribution to this forum - ur embarrassing mate

Reason I write this is out of frustration. If you contributed to this community in a positive way then I could understand but you can't so why don't u just **** off to whatever car forum u actually own?

[robsm]

Someone needs to ban this idiot

Well said Kev,

We're lucky to have SVM on here sharing in as much detail as they do. If it wasn't for them this place would be pretty dull.

[Nick Xoticar]

Nice one Francis and the Team at SVM ,
Love it when people go on about just changing cams only to make a car rev more , well they do but with the sort of horse power this things running would sure be a wise move to replace Rods and Pistons for stronger items so it Lasts at higher RPM and yep while you at it going for longer rods and shorter compression height Pistons to make it last and help it rev harder , I’ve done a very similar thing to a different engine altogether and because the engine has gone from 1599 cc up to 1951cc most people say stroker don’t rev but the decision to go long rods and short pistons has cured that problem as the car revs to 9000rpm now no probs

Please Google rod to stroke ratios, get some knowledge and then come back and post something.

9.71 @ 155 on 20" inch***8207;
Hi, F-man ran at Santa pod this weekend, drove there on is Road 20" wheels and tyres
Ran 9.70 sec and terminal of 155mph,

Only using 32psi fuel map and using his daily rubbers, looks very good for future Runs,

As the uk current champ 9.67@145mph, this may not seem very good, but I.m sure
the guy's in the know,will understand a 10mph increase in terminal speed,and not using his 18" drag radials,hopefully the New record will come

F-man experienced poor traction in fist four gear's

After completing his Run.s he drove Home Nice weekend drive LOL
Race maps,Race drag tyres and set up next time out, !!!!!!!!!!!

Thanks for ludders for his assistance again and well done on his blistering Run
we have to catch ya LOL
