OK, there are a lot of people tuning their FRST's at the moment and instead of me answering all these people indepently I'm basically going to tell how FRST tuning was for me and maybe enable some people to understand why you have to change certain parts to get good reliable power and why is not just a case of add a chip and have Max Power Magazine BHP straight away...

Right, going way back to when my Fiesta was standard my engine mods started with a Magnex S/S exhaust and a K&N57i Kit it was then tuned on Power+ Engineering's rolling road, My car could touch and hold 9psi as standard and at this stage it rolled 138bhp..
Then I got a Superchips 165 chip and took the car back to Power+ and had it tuned and setup again I wasn't able to hold anything above 10psi and had a new actuator fitted and was then able to touch 14psi and hold 12psi. Because the charge air wasn't been cooled enough by the standard intercooler 14psi was the max i could go without pinking, but yet I rolled 161bhp..
I then bought a chargecooler and had a Kent35K cam fitted and went back to Power+ and and i was then able to touch 15psi and hold it longer before it would go down to 12/13psi. I wasn't able to go any higher than 15psi as that was as much fuel my standard injectors could flow to match the cooler air, at this point I rolled 183bhp at Power+ and a very good 201lbs of torque.
Then came the beige injectors for higher fueling and a Superchip 195 chip to enable the ECU to match more fuel and air and control it (although this proved to be a crude map and made my car run lumpy at certain revs) I was at this point able touch as much as 18psi (not recomended) and hold at least 14/15psi, A 16psi special order Actuator was also fitted to try and help hold more boost but basically the standard T2 turbo was running out of puff at this level of power, It was never rolling roaded at this stage as it was set up on the road by SCC but I would estimate it was between 190-200bhp on a good day


So... on my car, the standard intercooler limited me to a max of 161bhp
When the intercooler was uprated the standard injectors limited me to 183bhp
When the fueling was uprated I was limted by the standard Turbo at 190-200bhp

BHP figures are only half the story, I've had to uprated my suspension, gearbox, clutch and brakes as these are just as important as without them big power is useless..

On the road, my first go at Santa pod was at the 161bhp stage and i did a very good 15.18 1/4 mile. Second time at the pod was at the 183bhp stage were i could only just better this time with a 15.01 1/4mile I then also did a 7.4 0-60 at a Revs event (RST vs Rovers) as I was suffering wheelspin and a burnt out clutch.
At the end of my CVH fun the best i clocked was a 14.52 1/4mile and a 6.42 0-60 at most recent Revs event.

So these are my experiences I had when tuning me turbo, hope it helps and let you understand why people in the know rubbish silly bhp claims when the owners have standard intercoolers or injectors!!


The Future... well the engines been sold as has the T2. A Zetec lump is soon to be fitted along with a T3 hybrid and I just can't wait....

Phew..

Good lad Paul... About time someone made some sense...

I'm not picking but i've been waiting for a reply from Steve RS, cause he claims 180bhp at the wheels... I would love to know where this came from and whats been done to the car.. but he doesn't reply to my posts?? I thought he was on standard intercooler and standard injectors... dunno...

Ohj, paul.. My engine is getting rebuilt temporarily (spelling) cause it gonna blow soon and i can only afford a rebuild and charge cooler... so after run in a setup should be over 200bhp... better be anyway!

[sunnyFRST]

Paul is getting all of these new monster engine mods done from the same place where I am getting my new engine done from (any guesses!? ) therefore it really doesn't matter if people come on here with their maddly over boosted BHP and power claims - because our genuine figures will p155 all over them anyway

Regards to your new engine mate - Just you wait! - Your gonna have to get a loan for petrol cause your gonna be in it all the time (you'll love it sooo much!)
I know I did and will!

Sunny.

ps - All of the guys with mad quotes always get shown up at shoot-outs and magizine days. Whats the point, who you fooling apart from yourself!?

[Paul R]

Thanks Ian, your getting there!
Charge cooler will deff be a huge improvement!! will it be a standard rebuild or better??
Good Luck mate!

[Paul R]

Sunny, i'm counting down the days!!!!
Its going to be fun!!!!
I might get shares in BP he he!

[Doc]

Can a standard T2 and a standard clutch/gearbox withstand 12psi / 160 ish BHP without any problems???
This is the spec I`m thinking of but dont want to be changing any parts every six months.
Doc

[snake]

Still running the standard clutch at 196 bhp!!

(paddle on its way though)
You just need to take it easy in first gear..
Depends on how old it is aswell.. New ones only £70 ish from Ford+vat..

12 psi should be o.k, if its the original turbo it may kill it off!!

Gearbox is the same, if its the original unit u may be better off getting it overhauled if you want it to be reliable..

[Fezzy Turbo]

nice one Paul

good to see someone talking sense

cheers, Greg (proven 140 @ wheels )

[Paul R]

Cheers Fezzy,
I always had a sight slip in my clutch if i was giving it loads on launch, but the Rovers vs RST killed it!!! at 183bhp level.
Then I bought a AP racing clutch with uprated cover and bearing and put in a ERST box with the LSD, 7.4 to 6.4 proves they made a difference!!!!!

Whats you guesses for how long the turbo and gearbox will last.. mileage wise, now on 55k, if the car was standard upto 50k, then 12psi for the remaining miles, how long you think them bits will last. FFSH, and i don't go fast that much, and never above 5k, what you think ? :grin:

Cheers, Mark

[snake]

Mainshaft bearings in the gearbox normally let go 60000 miles+..

My original turbo had 62000 miles on it and I put it upto 14.7 psi and it blew within 1500 miles!! They just aint designed to run big boost..
I`ve got full history aswell..

Every car is different as they are all driven differently from when they are built.. Some are ragged from when they were built, some never allowed to cool down properly etc etc

I know this is an old post but what an excellent write up

I've found my times are pretty similar (before you uprated the injectors and pump), which, considering i see you as some sort of galactico type makes me feel even more chuffed

My spec is

Ahmed 175chip
T2 Peaking at 15psi and holding 13-12psi
Pro Alloy big rad and Front Mount Cooler
Mongoose Exhaust + K&N Cone
Escort S2 LSD Box
16" Wheels

Est power 170-180.

Bloody hell, talk about digging up ancient posts

Bloody hell, talk about digging up ancient posts

I know but i found it a very good read

I totally agree with Dave excellent post

[Paul R]

bit of history there..

[BUTRE]

This post from Paul stated the real thing for the CVH turbo puting the so called tunners Mambo Jambo asside.

This facts with Ian Howels statements regarding the CVH turbo tunning helped me to layout where to go... and I hope to get there

[Ian C70T5]

Saw this historic thread, so had to pop my head in and say hi..
