Really zero drop off in power past 6500rpms, it’s a night and day difference. Instead of spending 15k plus in parts and labor for the X51 kit where you lose low end for high end gain, these runners give you 90% of the top end without the low end loss and it costs 10k cheaper (labor was 3 hours). These runners plus IPD plus GT3 TB - Think of it as a final f-u to Porsche for hamstringing the intake portion of this engine so it wouldn’t step on the GT3’s toes :evilgrin:
i cant go back to my ‘stock’ car anymore :icon107: |
Not too much but that’s what the 4.5L conversion is for :)

I thought Jamie said they didn't see further gains from the IPD plenum and throttle body with their runners?

Hey Jamie, I can see I'm just going to have to be a "bunny" again and give these runners a go! FYI we found we had to change a lot of lines of code (copied from a GTS ECU program) to get the heads to work properly as the the overall volumetric efficiency was outside the GT4 model boundaries. Did you find this with runners and somehow get it solved with just the COBB? Have you tired the X51 heads with the runners?

its way easier to just re code the car at that point. Lets chat offline via email. Ideally I’d love to see a before and after dyno on your car and we can help decide if Intake runners will make a significant difference or no... |

A bit of data for you boys.
Keep in mind this isn't an optimized tune yet... First one should get your attention... First Graph is Intake Runners - Dundon Headers and Tune (D3) compared to Stock GT4 https://cimg4.ibsrv.net/gimg/rennlis...3f38f70c0c.png Stock GT4 vs Dundon Headers/Intake Runners/Tune This Graph is showing the gains of the Intake Runners - Race Headers - Tune (D3) compared to Race Headers and Tune alone (D2). https://cimg1.ibsrv.net/gimg/rennlis...4a456483a5.png 37whp gains at 66xx rpm for D3 (Intake, Headers Tune), compared to D2 (Headers, Tune) This Graph is showing the gains of the Intake Runners - Race Headers - Tune (D3) compared to Race Headers and Tune alone (D2). Peak of D3 compared to Peak of D2 https://cimg3.ibsrv.net/gimg/rennlis...d1b7a7b55a.png 20whp gains at peak D3 vs D2 This Graph is showing the gains of the Intake Runners - Race Headers - Tune (D3) compared to Race Headers and Tune alone (D2). 60+ whp gains at 78xx over D2 https://cimg2.ibsrv.net/gimg/rennlis...8cf17c9e55.png 60+ whp over tuned/headers combo Are there dyno charts available that compares Dundon headers + Dundon intake runners vs the the same with the full recommend items (gt3 exhaust + ipd/tb)? |

You can run the stock exhaust, we recommend against it for anything that will see any track time as on the dyno the oil temps rose quite quickly with all the mods and the stock exhaust, vs the GT3 muffler adapter. We weren't comfortable with the temp rise so highly recommend people to get the the GT3 Over axles. |
I’ve been running the D3 e-tune and I decided to get a Cobb protune today for my D3 setup :)
Solid line - protune Dotted line - Dundon e-tune 95F https://i1067.photobucket.com/albums...203F090C1.jpeg Everything went smoothly with the tune, notably no rise in oil temps despite back to back pulls with PSE. I highly recommend finding a local br0tuner and getting a custom protune to match your octane levels, sea level, etc :jumper: |
