3.2 with bolt ons... GUESS the HP

[Qcurtis88]

Heading to the dyno tomorrow, so place your bets on whp

Healthy 1985 3.2. Here's the bolt ons:
- Steve W chip
- Steve W ported TB
- Custom 1 5/8" headers
- Dansk 2 in 2 out sport muffler

Told them to bring a couple extra ratchet straps to keep this thing on the dyno

Closest WHP guess gets a Stella's Garage Hat or 915 Shifter Spring

245 hp.

Sweet car color!

With a 40-year old stock engine that started its life at 207 hp, I think 220 hp would be a pretty good result.

[OSC911]

218

234 at the wheels!

Ant, assuming a 15% power loss due to transmission, 234 at the wheels would mean 275 at the flywheel.

Steve has some good data here from 3.2SS and 3.4SS builds, tending closer to ~250rwhp on some of those builds: https://forums.pelicanparts.com/porsche-911-technical-forum/1125595-fun-dyno-comparisons-3-2-vs-3-4-vs-964-a.html

Assumptions: yours is a US 3.2 (9.5:1 CR), you have larger headers (41mm) to let the top end breath more, but no cams, so you’re going to be a little limited there. You’re also in CA so will be on 91 pump gas. My 3.2SS with similar mods — 38mm SSIs, Dansk 2-1, 10.2 CR Mahles, ported heads, TB, 993SS cams, SW chip on 93 — is a hair over 250RWHP.

Guess: ~232RWHP on the dyno, or 257HP at the flywheel (11% loss). That might be a tad optimistic but you’d probably pick up a ton with some good cams.

California dyno’s add 30hp.

[rothaus]

I built a 3.4L for my Targa. 964 cams, SW chip, stock exhaust.

It pulled 217 hp at the rear wheels.

Your 3.2 with stock cams and headers, I would think 210 at the wheels would be nice.

BTW, I don't need more hats, LOL.

Cheers

With a similar setup my ‘88 read 217 at the wheels (~249), euro pre-muffler + SW chip + dansk sport (1:1) gd lk!

[Qcurtis88]

Some of you guys are being incredibly generous haha - I'd love to see some of these numbers!

My guess is 211 at the wheels.

It'll be good to see as the next step on the build is a 993SS cam + custom Steve W tune

This is a street 3.2 with mild cams I want to say 964 but I don't honestly remember, PMO ITBS and a stand alone that I tuned awhile back on an honest Dynojet with the newest Dynoware RT hardware and Winpep8 (new hardware tends to read lower than the old stack and Winpep7).

It had big, heavy 17" wheels fyi.

[Mr. Merk]

207whp!

Lucky you, my bored throttle body got lost in the mail when Steve sent it. I'm SOL

[evan9eleven]

Euro comp or USA?
Assuming Cali 91 octane?

[fallingat120mph]

209.5

Steve’s tune for the 993SS cams is great. Redline comes on FAST and you really feel the engine breathing when it hits 5k.

I actually have 101 race fuel in it right now.. who knows if this will have any impact but figured why not

I'm really excited to get this in. Heard good things as well!
