My Guy here is very knowledgable and honest. His take was basically " if you port it you ll see your max HP goals at a bit lower boost 8-10PSI while unported you have to use 11-12 PSI for the same #" this is something my small brain shares.... we forcing air into the engine regardless so no need to make it a smoother surface for my goals . i believe it can make a difference at high HP goals but not bellow 800HP exactly I will aim for a E85 carbed setup since i have a Holley 4150 DP here anyways and so i just convert it to E85 What i will probably do is to install a temp sensor bellow the carb in the intake and a temp sensor in the hat. this guy here has me convinced thata Blowthrough E85 doesnt need a IC: In terms of compression ratio + boost the timing and possible detonation is the problem with good timing you can prevent that. For sh#t sacke my 2022 GMC sierra Duramax ( diesel) 1500 has a 3.0L inline 6 Turboed, with Hypereuretic pistonsthe engine is 15:0:1 (Btw great truck, gets 31mpg with same towing and torque as the GM V8 1500s)
I got the heads done, but I'm loaded with travelling for work + finishing my buddies 65 C10 LS swap to come back to the TURBO engine.
Update: so the engine is almost complete, it's just missing the rocker assembly installation and pulleys. I got the heads magnafluxed and resurfaced + TA STAGE 1 VALVES and STAGE 1 + SPRINGS. I. Also plugged the exhaust crossover and I got some weight savings by painting my iron heads aluminum lol (min 50lbs hahah) I also installed a 10 an plug in the oilpan as a turbo oil return. New lifters. New pushrods all oem specs. Looking good so far I think.
PS i drilled into the Intake and added a IAT sensor for later since i would like to monitor the intake temp below the Carb
Idk about that yet. The C10 runs awesome as is so I don't want to mess it up and the 455 in it is a handful for the lil truck already. + it has a AC in the place of where the turbo would go. I love AC especially right now.. TX burns
Hey Guys Sorry for long time no hear, i was loaded with Work , had to travel Overseas and took the chance and had vaca in Germany to visit some family, it was awesome. i finally worked on the wastegate location , i think it is pretty ok ( not perfect but i accomodate the exhaust flow and im sitting fairly close to the turbo so it should work OK i think. please dont mind my choice of material i literally pieced it together from 2.5 In Exhaust tube i had laying arround # no pretty bit finctional. i am pretty sure i am able to route a 4in Exhaust goin to the back and down under (almost ) any car. i mainly oriented it towards a GM A-Body since i have a 68' Buick small Block twin turbo (63s) and maybe replace that guy with this 455. Once i know the car i can work on some reinforcements for the 90 Turbo Vband mount. Or i fab a bracket that mounts behind the Alt and arround to the 90 Mount( creating also a heat shield for the ALT. PS i need to get a 2.5 Vband clamp the one that came with the ebay 60mm wastegate SUUUUCKS
Looks great, thanks for the update! If you don’t mind me asking what size pipe did you make the log portion out of?
lol... i can see my block saying Chiao Chiao ahahah I ordered some parts to convert a 4150 750cfm DP to BLOW THROUGH (1st time DIY) it should work i should also look for a nice project for it soon, i thought about a Big Body Buick Centurion, Electra etc, something that has engine bay space lol. I think that would be cool i take good car leads
I've recently been thinking about how fun a boattail riv or wildcat with a setup like this would be. Let us know how the DIY e85 conversion goes. I've seen some kits out there and at some point would like to make the transition too.
i go by this guys DIY tips. its very reasonable if you buy the parts separate on amazon/ebay/summit I have a 750 cfm 4150 DP sitting arround that is perfect for this there is 3x videos
Are you married to that wastegate location?,...the 90° that close to the wheel isn't Goin to manage boost that great. Can't sweep it under the turbo,..inline with the flow?
I know but i have a hard time mounting it under due to ANY frame clearance issues i think ( it will be sooner or later in a stock frame car. As far as my research went , i learned perfect would be in the 90* vband turbo Mount going with the flow/ direction of the log , if not then as close to the turbo as possible and going with the flow as best as possible. Its definitly not 1000% but i am sure it will work
But yea with that comp and corn your IATs won't be terrible under 10lbs,..which any more than that and IATs will be of little concern vs driving over the crank ha
