John. I would give Scoobyclinic a ring. There is another 60ftlb to be gained with a good map. Power sounds good but you will notice torque on the road.

I have the printout yes, just need to delete the customers registration number and personal details off there before I can upload it, but will try and do it before I go today. 0-60 times etc will be done next week when we can test it properly.

Been really busy out of the dealership today, working on our next Modifica WRX STi v2. I am afraid I am not doing the 400bhp version anymore, instead I am doing a 450bhp version.

Littleted

thatll be a 10k uplift then ?im pretty sure the well renown modifiers wouldn't touch 450 unless the block was fully forged internals ?

Think cheapest quote I got was 7k

Lichfields wanted 20 LOL

Mangoletsi Subaru

My target is sub £40k for the car, but absolutely it would have to be and will be forged internals without doubt.

Littleted

good number though 450 vroom

Printout attached. This is a car that has had the exhaust and re-map.

Will it be a closed deck block? Getting close to the reliable limit for the standard block.

Mangoletsi Subaru

That was one of the things he was talking to me about today, so maybe yes, but he is the expert, he's done it for over 15 years, so I am in his hands, and we have to build the same tolerances in so that a warranty can be offered on the car as well.

Mangoletsi Subaru

Sounds better than 400

Littleted

but your so close to 500 it would be rude not to

Mangoletsi Subaru

That would be nice, but have to draw the line on cost somewhere, sadly.

Another 60 ft lb would make a 100 ft lb in total increase over standard? I assume you mean 60 ft lb total increase over standard. We can and have achieved that, but it puts the engine way too critical on temperature, and there is no way we would cover that on warranty.

If it is 100 ft lb, there must be some serious additional cooling on board, as there is no way a standard engine can run that amount of extra torque for any length of time.

Would be interested to see the list of mods done, and dyno printout.

See scoobydoo link above.
It is 100ftlb of torque. But it was mapped by the master Pat Hepburn.

Might be some new figure up today for a billet turbo addition.

Mangoletsi Subaru

Not able to view it for some reason?

What else was done to the car?

Cheers terzoscooby. What else was done as well as re-map?

terzoscooby

From memory just Miltek sports cat, Miltek system and remap. The magic is in the mapper.

Mangoletsi Subaru

OK, studied the map and with the exhaust system and sports cat as well, it does make complete sense now. However this isn't something I would be offering and willing to warrant.

The biggest issue you have with them is the crap radiator which is fitted in std form, they are like this to keep the engine at an optimum higher temperature to get the best fuel efficiency and emissions as possible. your best bet would be go down the route of the earlier hawkeye rad or a big core alloy version. 2.5's have been known to run quite warm when pushed on.

You also have the issue of the clutch, 400lbs of torque is quite a lot to put through it, the map John has is for reliability and drivability to retain the warranty and tbh its the best of both worlds, not just which mapper is best but you need to look at a wider picture on a new car with a warranty.

terzoscooby

Well this could be an interesting debate. It is all a question of thermodynamics. Now if both engines are running the same boost it is likely the lower torque one is running hotter as it cannot breath and get rid of the heat from the cylinders so timing has had to be pulled to stop detonation. As the turbo is maxed out at 340bhp it is likely they are both running full boost from 3700rpm. There is more to mapping than winding up the boost and altering fuel and timing tables.

I am sure Subaru don't use a small rad for quick warm up as this can be achieved with a thermostat. More likely cost.

The clutch will depend on the driver if it doesn't slip at 400 ftlb then no issue. And that has been proven Clutches only wear when they are slipping so if you ride it a lot or do lots of launches then expect problems.

redace

Torque is effectively the force produced by each 'bang' in each cylinder, power is a function of this relative to how many of these 'bangs' occur in an amount of time e.g RPM. Not wanting to have to regurgitate years of thermodynamic engineering teachings right now, but I'm certain (without getting into extreme -20 degree turbo anti-lag setups or engines with timing problems) that an engine producing less torque (less bang) does not run hotter.

Mangoletsi Subaru

It's actually the other way around Terzoscooby, as redace says, the more torque, the bigger the bang, the more heat, and heat is the killer, that's why with just a re-map we dialled our's back to prevent det or sudden power drop off.

Agree with you on the clutch though, don't see a problem with that at all.

terzoscooby

I agree with the bigger bang makes torque but if the gas cannot then get out of the cylinder you get heat soak and pumping losses and retard ignition. So back to my conditions for two identical engines running the same boost pressure but one being able to get rid of the exhaust gases better than the other the result is lower torque and more heat soak.

Wow, this thread has evolved since I last visited.

redace

On a 'regular' engine, the exhaust valves are belt/chain driven (non adjustable/mechanically driven) and with the piston heading north at 90mph towards the open exhaust valve, that gas is coming out whether you like it or not.

Are you talking about the vvt tuning on the exhaust cam?

If each car is being setup individually, what fuel are you using. Are you stating one specific type or a broad range from 97 to 99 as this will have a big factor into the figures being lower than Scoobyclinics if your trying to go broad scale.

lower RON fuel you are no going to want huge amounts of torque from a 97 as it would most likely not take the timing so would det for fun...
