exhaust porn

I was making a performance comparison not a technical or engineering one, I know where I put my money with my exhaust manifold and it wasn’t the Ronin, even though I could have saved some cash, I didn’t think the build quality or overall design was anything close to Jim’s :smiley:
Probably most upsettingly looks wise mine is covered in blue Zircotec as I now can’t see the lovely welds :wink: However temp wise it was well worth it, actually thinking about it the Blue Zircotec matches my car :wink:

Cool “blue” mate, don’t forget the weight saving lol

[quote=ade]To get 300hp you need to add boost, about 10hp per psi, however the charge temps rocket with the extra boost, I am running the max boost for standard internals of 9.5 psi, if you don’t keep the cylinder temps down with 9.5 psi you will get det and it doesn’t matter how good the knock sensor is the engine life will be seriously limited.
What I really like about mine is 205lb/ft of torque I now have not 300+ hp, its all in mid range and high end torque that makes the car so driveable, and on track I can sometimes take a higher gear in a cornaer which is easier on the car as I don’t have to red line it so much.
Overall you are right with a boost upgrade you could make 300+ on your inter cooler but you will limit the engine some what in life, and on track you won’t have 300hp for long as the heat soak will take it all away.
Are you going on the 30th? If you are you can have a feel of the temp of my CC outlet pipe then compare it yours, I’m positive it will be like day and night in comparison. [/quote]


Hi Ade,

Sorry only just spotted this, I am not looking to change the pully and add more boost so the temps would hopefully not go up that much.
Yep I am going on the 30th and will take a look at yours as I am interested to have a look at your set up :slight_smile:
Testing pipe temps would not really be that fair though as mine would heat soke pretty quickly after a track session as soon as the air speed drops on the cool down lap and on the way back in. The only way to do it would be to actually data log the AIT temps on track.
Sinclaire are unwilling to tune up my set up as they say an intercooler runs 20deg hotter than a chargecooler, I cant really buy that tbh apart from on their dyno with zero air speed. They are quoting a max of 230rwhp and cant answer why Charlie seems to do much better in the states or why there results seem patchy on intercooled cars so I am looking into other options. If push comes to shove and nobody can tune it (hopefully there is another option on the way) I’m most likely to go Komotec as its a complete kit and seems better VFM than the sincs option imho.

cheers
