Thank you all very much for your valuable opinions.
After investigating hundreds of them, I selected a potential donor: 94 Buick Regal rack.
It has the most acceptable attaching mounts (slight rework required), and is comparable dimensionally. Also it has the same pitch and range and uses the...
I'd like to add a GM power steering rack on '88 Lotus Esprit turbo (2900 lb gross weight).
I'm looking for a suitable part which has similar((+/-) attachment spread/points to the chassis.
I found several potential donors, but have difficult time to find a right attachment spread.
One of the...
Hi All,
I'm considering replacing manual steering rack in my 88 Lotus Esprit with a hydraulic power rack.
Whilst investigating possible donors, I found that racks on
BUICK ALLURE 2005-2009, CENTURY 2003-2005, LACROSSE 2005-2009, REGAL 2003-2004,CHEVROLET IMPALA 2000-201, MONTE CARLO...
I am interested in this: how the rear suspension dynamic or ride properties will change as a result of replacing the existing 14" spring with 12" new spring of the same spring ratio?
Suspension type: single longitudinal swing arm w/upper and lower lateral links, single 15 deg inclined coil-over...
Hello,
I'm prototyping a variable volume(NOT variable runner length) intake plenum for t 2.2L 4-cyl turbocharged engine and have a few questions.
Analyzing Italia 458 IM design, one can notice 3 various valves showing the proficiency of engine designer in figuring out how to command and...
Thank you all for your great responses.
No, I was not arguing w/my boss.
It was a Motorsport enthusiast, with whom I was discussing details of a water to air inter coolers.

Hello Everybody,
Could you tell me if/where I'm wrong? Perhaps, you can point me toward other equations/formulae for heat transfer ratio applicable to air-to-water HE-s?
I'm trying to prove someone wrong.
This individual insists, that because of the higher coolant velocity (if I use a larger...
There are numerous and often confusing postings throughout the internet on this subject. Not too many on turbo engines/camshafts, though.
Let's assume, we have two identical 4 cyl 16V, DHOC engines, boost onset at 3,500rpm, same SLA values and the only difference is in intake camshafts. Both...
On Lotus L4 and V8 engines the top of the liner seems to be held in place only by the "nip" of head gasket. Frequent failures of gaskets have been reported, especially on tuned turbo engines.
The theory became that failures are related to the liner "panting". Also, experienced builders recommend...
Here is a diagram of the links in plan view. (The sketch proportions are exaggerated.)
My initial concern stemmed from the observation that making links "more parallel" reduces the forward reaction at the upper link hub carrier joint (R1<Ro) AND it probably affects rear Caster (?). Question is...
Hi,
Could anyone point me in the direction of some paper or analysis of the automotive rear suspension with the following characteristics:
- single independent longitudinal radius arm w/rigidly attached hub carrier (knuckle), (NOT 4-link!)
- upper and lower, un-equal length links...
Thank you everybody.
Well, I could go with larger D and taper down the ends to fit inside the control arm sleeves.
4130 or perhaps 4340 would be better?
Mater artium necessitas
I have D=15mm ARB with ~ 100 lb/in stiffness, made of 4130 steel.
I would like to make a new 20-25% stiffer bar.
I'd like to keep all the dimensions the same, if possible.
Would changing to a different steel grade with higher Modulus of Rigidity change the stiffness enough?
Going thicker on D...
Thank you Hemi!
You are right, closer to TB-s is better.
Brian,
Could you elaborate on your notion of "non issue" and "arrange" in non-presumptuous way?http://files.engineering.com/getfile.aspx?folder=c2f822d7-1049-45d6-ac74-b7f3c860a09d&file=J_H_engine_&_CC.jpg
