600 RWHP what’s needed? Future proof & cheap way

[reNeglect]

Hey guys!

currently have Visconti Flex Fuel kit, AMS catless downpipe, AWE resonated touring cutback, MST V2 intake, tuned by Marin Nelson.

curious I want to take the car to my next power goal, which is around 600 rwhp

I know we can just do Pure800 with either 93/94 (I’m in Canada, we have 94) or e30 blend to achieve those levels.

but what if I want to futureproof the build so that as I continue the build. For example, if I went with a aftermarket big single, then later added port injection and HPFP, then built tranmission?

also want folks to chime on their mods and current power figures...

For 600 you definitely need a transmission upgrade. My friend has a pure800 with downpipe intake tune and hes making roughly 520hp-ish on 93 and his transmission is slipping. had to be dialed back from 540 to 520. But for the others I think you're right on the money, need port injection and hpfp would be good

HP numbers aren't interesting for the trans, torque numbers are. Stock trans is good to around 550-600 tq, then it'll need to get built.

Curious why you're basing your goals in power and not times though. Do you have a 1/4 mile time in mind you're trying to hit?

Basing it off power, as I haven’t gotten a chance to formally do a ”official” 1/4 run or a 100km/h - 200km/h (60mp/h - 125/130mp/h)

so would it possible to achieve 600 rwhp and dial torque back ?

It's going to be tricky to dial the tq down lower than the HP I think. But you can tune to stay under the limit for sure.

Lost me at cheap my guy...power doesn't come cheap you will pay for it one way or another.

Pure800 is a relatively inexpensive upgrade vs a big single. But both require fueling upgrade and pure transmission. I guess my ask here is honestly what most people have done here and what their experience is

Pure800 is what most people on the forums have done. There are a lot of big turbo guys making a lot of power. Going with a big turbo is a huge commitment, and you'll likely spend significantlly more money.

As far a single goes. Single is the only option. Replace the little one with a stock frame or top mount.

I would love to have a pure800 on a decently conservative tune, on 93 octane, and make the power that I currently make on E40 stock turbo, and this is completely possible on the stock fueling. I just need to save up the money! What I may just do soon is get a methanol kit installed and tune for it as well. As far as a stock turbo goes, Meth and ethanol would get me really close to 550whp and close to 600wtq and this is all I need.

Yes you can if the tuner knows what they are doing.

You could plot everything based on math if you wanted to get a better idea what kind of torque you would need to make for your 600whp goal. If you want to stay under 500wtq, make 600whp but still have a full torque curve, it would look something like this:

RPM	Torque	Horsepower
5000	490	466.5
5500	490	513.1
6000	490	559.8
6500	485	600.2
7000	450	599.8

Pure800, PI, reflex, downpipe, e85 would get you there. But as it’s been mentioned and I’ve said before, build the trans. I thought I could run a pure turbo and dial the power down, but that didn’t work out. I did the pure stage 1 trans upgrade pretty much away because it was slipping like crazy. Now I’m in dire need of axles but no one seems to have any.

I've been on the wait list for axles since Sept. You should get your deposit in yesterday. It's 3-4 months when your on the list.

600whp is about the limit, after that the trans will slip. Luckily, the clutch packs burn and wear out and not the gears. So a rebuild or upgrade will only need Hellcat packs.

I believe it looks cheap initially to upgrade the turbo on these cars, but it’s really not “cheap” to do it right. A pure 800 little over 2k, but to get the most out of it you need a fuel system, so the plate and injectors, LPFP, and controller another 2.5k, then the trans is going to slip. Saw the debate on the FB page about pure trans stage 0 vs stage 1, and it seems if the bigger turbo and maxing it out is a goal then stage 1 is another 6k, then axles, 2k. I don’t see anyone ever talk about a driveshaft, but now you need proper wheel and tire to put the power down. To do a “proper” turbo upgrade you’re looking at 10-15k depending on where you get the parts and who is installing it.

that doesn’t mean you can’t go buy a pure 800 and send it on what you got with the boost turned down and all. I know many are doing just that, and if I had to buy right now, exactly what I’d do since I don’t have the rest saved up to just drop on everything else that’s needed.

This is the insight I was looking for, which confirms my suspicion. It seems way to good to be true but it’s not half wrong either.

Depending on power goals and upgrade path. Eventually I would love to do the upgraded intake manifold and port injection along with it.

Mostly curious if I did the Pure800 how much power can I make safely, before fueling upgrades, then drivetrain upgrades.
