and how would you increase compression ratios?
i've heard this is also the disadvantage of schrick cams being too much of a performance cam, you do lose out low down. while with the kents and the newman's this doesn't happen as much??

I have a Schrik cam, Shrick valves and GTT stage 4 head & when used in combination with my other mods I do not believe that I lose low down power / torque. True that above 4000 revs things get wild very quickly but low down I have still gained.

Proof is my 30 to 70 time in 3rd gear of 5.1 secs tested on Bens racelogic box of tricks

Hope I all gets sorted soon.

it has been an interesting experience which is becoming an expensive one!, i tell you what would be more interesting!.... a thread on all the comments/claims/criticisms made by all the tuners about other tuners i've spoken to (5 tuners out of 8) and then get people to vote "true/false" regarding their comments in a poll.(obviously keeping tuners names anonymous) that would be interesting - but then i'd get banned 3 tuners didn't do that at all.

what mods have you got to help low down?

That is a good idea to be honest but I don't think it would be allowed. I know a couple of tuners that work well together and generally it should be like this as at the end of the day you as the customer want the best advice and not be ripped off. Your in good hands sayanthan

every business has a right to promote and defend their products and services and that will inevitably involve criticism of the competition -i see it all as good fun really and would have no qualms about using the majority of tuners i've spoken to.

minimania (adam is the fountain of all knowledge) are down the road from 1320 (won't rip you off) and they get on with thinkmini who happen to also sell gt tuning's products! since roland and paul don't really talk. so there's a nice mix/group right there.

I do not track my car but all the extra torque is great on the motorways and A roads I use.

you should check this link - adam at minimania has an alternative explanation - on page 12.

Thats right, we find the shrick has excellent low/ mid power as well as top end obviously.
And Alans car is proof of this. The art is getting enough fuel in. ...GTT440cc + GTT Adj FPR achieves this very well, without even necessitating a remap.

[blaze6]

well i've decided what i'm going to do, and i know i'm going to be criticised by some people on here:-

once the grs arrives and my uprated radiator is fitted, i'm going to thinkmini to have 450cc injectors and AFPR fitted and setup along with getting a newman/?1320 cam fitted either at 1320 or think mini. then i'm going back to 1320 to get the car dyno'd again to see where i'm at. then either do a remap with the 19% pulley or switch to 17% pulley with a remap.

i'm hoping the uprated intercooler + radiator will lower IATs by 5c at 7000 rpm (ie reducing IATs from 69 to 64)? feasible??

and that the 450cc injectors + AFPR will sort the AFR leaning out and possibly reduce the IATs a further 2-3c at most. the conversion should then be safe. a remap may be able to do the rest after this.

if remapping a 19% not feasible the i'll go with - 17% pulley+new supercharger (both of which i have;blades not ground in) and a remap. but I would like to make use of what i have

the GRS intercooler and 450cc injectors will complement whichever pulley i do with.
i will be getting kit to monitor IATs and AFR.

adam feels sticking with a 19% pulley is feeding the "addict", so be it.

regards,

"the addict"

ps:maybe i should change my mini2 name to "crackhead"!

Sayanthan are you running water wetter in your coolant? Remember to add a bottle when your new rad goes in!

water wetter? - what's that?

What it says on the tin lol.

I have seen this used when I used to race motocross, on tuned engines it helps the coolant temp

so i add this to the 50:50 coolant/water mix? does it really help?

[MINIMANIAUK]

No - it is really to be used in place of the coolant and with water only -preferably distilled water

Coolant (anti freeze) is added to water 50/50 normally -this is to stop the water freezing and to lubricate water pump and to inhibit corossion and lastly to raise the boiling point a bit higher

But antifreeze does not transfer heat as well as pure water , so less heat is transferred to the radiator with anti feeze mixed with water
If pure water was used then no lubrication, corosion inhibiting ,and anti freeze is available - so a water wetter is used in place of the antifreeze during the summer months ,it then lubes,inhibits rust and reduces the water temp - the boiling point is reduced but this is off set by the gains in cooling ability ,extracting heat from the engine into the water and then via the radiator to atmosphere , seems more popular in the US than here!

oh i see, so i guess you could get caught out if there was a cold freeze over the winter, unless you do a fluid change twice a year. never heard of people in the UK doing it.

[Bhozar]

I usually run water wetter in mine, but with reduced quantities of anti freeze. I didnt think I needed protection down to -18 degrees which is provided by mixing it 50:50.

that's what i was wondering about - is it safe to combine coolant/waterwetter/water? does this negate the effect of water wetter?

[blaze6]

i've been asked to post the comments of tuners i've spoken to, i think it's best to keep tuner's identities anonymous if i do this!

tuner 1 - " tuner 2 use older archiac injectors, we've seen some of those american's cars and their injectors are the same. it's not just about size you know.. "
"don't trust their dyno, go to a non mini one, one with no vested interest"

tuner 2 - "tuner 1's intercoolers don't fit, you need to cut the bellows"
"tuner Y's cars go bang don't they?........" (tongue in cheek)

tuner 3 - "we're stuck in the middle"
"we can't trust anyone else to set up that product in case it's not done correctly - this may unfairly bias customers against it"
"Tuner 1's intercoolers don't need brackets, they have snoot boots"
on tuner 1's comments about tuner 2's injectors:- " yes this might be true " - ?is this the supplier of both tuner 1 and tuner 2 ??

tuner 4 - "the R53 cooper s does not have a fuel filter"
on sounds coming from my car's suspension:-"it's because you've got upper and lower alta rear control arms" - they fitted these and koni fsd's - it turned out to be the fsd's making the noise! the fsd's which were sourced by me were faulty unfortunately. when replaced with stock dampers the sounds went. - so these things aren't taken out of context - i think these guys are excellent and would use them again-they did a great job on my car.

tuner 5 - "there's no telling the untold damage done to your car putting it on a dyno......they should have stopped before the IATs went that high... minicooper s's are not safe to be dyno'd, as they're supercharged engines..."

tuner 6 - "we've dyno'd a few of a certain tuner's cars, the mapping's awful-cars were running lean. our dyno setup's a lot slicker than tuner X's..... not many people like to admit we've tuned their cars..."

tuner 7 "you're feeding the addict...."

tuner's 4 & 7 made no criticisms of other tuners and/or their products

tuners 2-7 advised me to go for a larger 15/17% pulley. tuner's 3&4 also suggested bigger injectors possibly.

tuner 1 suggested an independent dyno first, he also had a product you can combine with bigger injectors which he felt would be enough to keep my car safe with a 19% pulley although he doesn't sell a 19% pulley himself.

tuner 3 advised against running a 19% on a track day but feels it should be possible on a road car with the right mods.

i've had the best customer service i've ever had from tuner 2, i can't comment on his work yet as he hasn't done anything on my car yet. this is out of all the garages i've been to, i've driven bmw's & porsches in the past and these guys definitely come top in that respect. judging from other people's comments they do good quality work too.


It's also worth saying that i think it's fair game for tuner's to promote their products and inevitably this will involve criticising other tuner's products when you want to demonstrate why yours might be better.....but you don't have to do this!!
