Supercharging query.

[MONKEYSOCKS]

Was debating getting rid of the zed, but now I'm thinking of doubling down. Mines a 350z gt4, with invidia gemini exhaust, cobra hfc's, mrev2 plenum, 5/16 motordyne spacer, with ecutek remap done. Would like the car faster for road use only, but want to be conservative with stress on the engine, would be gutted if it blew. To run 350whp would hks supercharger, fuel injectors, fuel pump, oil cooler, colder sparkplugs be enough to ensure no damage to the engine? Or would i have to look at other things to eg. Rods, pistons, radiator etc? 

 

Any feedback would be much appreciated before I make expensive mistakes.

You will not cause any damage at 350 bhp providing you fit the proper mods and get a good tune.

 

Forged internals will definitely not be required

 

Remember that it is torque that destroys engines and not bhp

[MONKEYSOCKS]

Hi Alex, what engine mods would you advise for 350whp then? Think that's just over 400bhp. In terms of non engine mods, ive got dba T3 discs, performance friction pads and goodridge braided lines fitted, would that suffice for brakes? Suspension is bilstein b6 shocks/tein s springs.  Guessing I'd need to upgrade the clutch at least as well. Would the xtreme kit do the job? Sorry for all the questions. 

[ZMANALEX]

That is not big power, so as long as you get the fueling and ignition correct as per your list and you use an informed tuner, then all will be good.

 

I would not stress over the clutch at the minute, depending on the current condition of course

 

Supercharging offers you a more linear immediate power delivery.

[MONKEYSOCKS]

Okay Alex, so the supercharger, fuel injectors, fuel pump, oil cooler. Should do the job? 

[ZMANALEX]

Perhaps a fuel return system, fuel regulator, and a set of plugs.

 

Remember the intercooler and associated parts.

 

Stock radiator, stock fans, and stock fan housing will all work, so no need for unnecessary expense there.

 

Good luck with your build.

 

Who are you entrusting with the tune/remap?

Spoken to Mark at abbey and Chris at tarmacsportz so far. I'm based in Manchester though.

Best to also speak to Mark or Chris to get their views on the essential upgrades.

Cheers for the feedback mate. Appreciate it. 👍

I'm running just under 380bhp on mine with a Vortech charger, so low boost using the standard pulley size. Use it for trackdays so gets a fair bit of abuse. I used the kit from Torqen, so has fuelling/plugs/oil cooler etc sorted, and with a Koyo rad to help the cooling.

Standard Brembos with a good disc/pad/fluid combo works fine for me. 

Hardly uses any oil, and still on the standard clutch  for now. Engine on about 105,000 miles, was tuned at Horsham a few years back and is super reliable. (Hope I haven't jinxed it now and I blow it up!) 😂

[MONKEYSOCKS]

Cheers for that mate, i know you use it for track but how would you say it would be for road use? Is it mental loud? Would there be lots of drone on motorway etc? 

[Ekona]

Adding an SC won’t make any difference to that, any drone or booming will be 99% down to the exhaust you use.

That's good to know, waiting for Mark from Abbey now, to get back to me. 👍
