Intercooler Test (Pics added Page 10)

First off a massive thanks must go to Pete and Darren of Spec-R for bringing there intercooler and helping to remove and fit all the coolers and rad 
They also saved the day with a spacer to move the rad forward otherwise both the Spec-R and Airtec intercooer would not have fitted.
We started the day testing my original 50mm intercooler.
We had more power from the start today due to the Air Temp being 11 degress cooler than the last time my car was on EPs RR, this gave a bit more boost midrange.
Run 1 Start inlet temp of 26 and finish 42 Power 466.6bhp
Run 2 Start inlet temp of 27 and finish 43 Power 466.8bhp
Run 3 Start inlet temp of 29 and finish 42 Power 468.3bhp
Air temp was 11 on these runs with a intake temp of 15
Next we fitted the Spec-R intercooler.
Air temp was 15 on these runs with a intake temp of 19
Due to the 4i bumper being different to a 3dr we could not refit the bumper correctly, also due to the intercooler being thicker my oil cooler would not fit in the position i had it in so had to be cable tied to the car.
Run 1 Start inlet temp of 22 finish 36 Power 473bhp
Run 2 Start inlet temp of 25 finish 36 Power 476bhp
Run 3 Start inlet temp of 26 finish 37 Power 474bhp
We then done 3 runs with the bumper removed as due to it not fitting correctly with the Spec-R intercooler it was covering most of it up.
Run 1 Start inlet temp of 24 finish 27 Power 478bhp
Run 2 Start inlet temp of 21 finish 27 Power 480.8bhp
Run 3 Start inlet temp of 20 finish 26 Power 479.1bhp
It was noted that during the power run NO INCREASE of temp was noted, only when the throttle was shut did the temps rise.
We then fitted my Modified Airtec Intercooler.
I had different size pipes fitted due to the standard ones only having a inside diameter of 53mm, i had these changed to the same size as my original intercooler of 61mm inside diameter.
The bumper was refitted for these runs.
Run 1 Start inlet temp of 22 finish 27 Power 478.2bhp
Run 2 Start inlet temp of 22 finish 28 Power 479.4bhp
Run 3 Start inlet temp of 23 finish 27 Power 478.8bhp
Air temp was 12 and intake temp of 17.
With the Airtec intercooler fitted when the throttle was shut you could hear the air causing some turbo surge but the Spec-R intercooler did not do this.
It was a shame that we could not road test the car with the Spec-R intercooler fitted as im sure the inlet temps would have been even better on the road.
Also on my journey home the Airtec did not perform any better than my original intercooler with the inlet temp around 15 for both coolers. Also both seem to take a long time for the temps to drop if you have a bit of heat soak.
Will add more if i think of anything
Better thank Luke and Danny LOL

Nice to meet you and the guys at EP today.
Good results all round for you and your car today
The little mod/bracket worked well, and i will look at doing a different one for you this week to bring the rad back towards the front.
Thanks to Luke/Danny for the time on the rollers and thier crew for putting up with me borrowing tools
The Spec-R website is being revamped as we speak, and will be live hopefully by the end of the month.
Regards
Daz

Why did your dad build a more powerfull engine for then???because he could thats why!!!
This cooler is better for more reasons than just getting 10 hp jimbo so really mate as usual your missing the point!!!lol
In petes words on mad ades car they see alot more than 10 hp!!!and still with better temps also its more down to air flow and air speed...
What youve just said is like saying why put that much better inlet plenum on my car??although its far more efficient in flow etc it only makes 10 hp more so il just stick with my std one!!!!LOL
cheers danny

I'm talking about martins, and my dads car, they rant bloody race cars if they are seeing 40 degrees over a possible 35 do you think they would stop the car,sulk and pay Ł700 for a new one because it flows a little better and cools a little better ?
Like feck they would, their engines are safe, doing the numbers and doing the business, they don't need to change a thing !
From what I can see everyone is getting caught up on minor details here

any engine in the realms of the power your dads or martins is would benefit from one..
Iv got a pro alloy mate and as said it works but if i fit a spec r and its better then i havnt wasted Ł700 have i???

I cant promise you anything martin but its been tested on a few cars now with great reults and if it proves to be better on mine then im sure it will on yours too..
Id be willing to let you try mine over winter if you like???

I'll ask Martin, does your car surge mart ? I know that awnser
I know my dads dosnt so what am I twisting ?
No surge then power is smooth all the way
We use a identical intercooler in car to the dyno
Would you like a graph to show just how smooth it is ?

The thing is, if you lost 5 degrees act and managed to put a couple of degree in the map what are you going to gain ? Ten bhp ?
What use is ten bhp at 700 btw lol, on a fun track day which is non competitive
People get too strung up on getting the absolute late bhp out of the car it's too ott for me !
Were not race teams fighting for championchips lol

) so without also testing theirs cannot say conclusively their i/c's are worse.

IMO the figures cannot be classed as fair as the test wasn't the same all the way through. The bumper makes a massive difference on air flow does it not? So surley you have to take the results for the spec R with the bumper partially fitted, not removed?
The test on the original 50mm Radtec Vrs the Airtek is a fair one though.
I do find it very interesting when new tech comes out and the improvements over the older tech.

Thing is the info has been posted up to help people on pf just like it used to be....But now you get people like jimbo jumping on every post looking for faults because of who his dad is...
I am currently building a 500bhp engine using euan's old t4 and im looking at new intercoolers so this info might not be much use to martin or jimbos dads car but to me it helps me make a decision...

It has nothing to do with who my dad is, I hate that
Its to do with me learning ! (bit like yourself ? ) If I wasn't tarred with the " his dad owns scs" brush you wouldn't be having a go right now, you'd see me trying to learn,
If that's ok ? I like to see everyones point of view
If you don't like by posts there's is a block button,

Ł700 does sound expensive i suppose ,but someone has to pay for the development of new products i suppose .its probably time for the competition to step up and improve on what spec r have achieved which in turn will bring the prices down to a more affordable level for us all.

I already have a rs500 cooler on me car but the only markings i can find on it is ( AHF 044 ) so unsure what it is but would rather have all the right bits on when it goes to be maped rather than finding out it needs more bits changing to get the best out of me car....
I know you would prob not benefit much from it but people like me would, Thats all i was trying to get across...

Wasnt ment as a dig Steve ,but would be good if one of the mags did a full test of all the coolers like they did years ago.
When I changed my coolers to Bell bar and plate type ,i did a similar back to beck test on the road and got the same sort of results with boost increase,quicker recovery and lower temps.

I can see what you mean but it is good info for what coolers are working at that power level as thats what im aiming for plus there will be his old pro alloy cooler compared to his new spec r when its done and hopfully he will post the results up so we can see how good it performs against a good quality cooler...
